Everett Interpretation in Philosophy of Physical Science. The relation between quantum measurement and thermodynamically irreversible processes is investigated.
The reduction of the state vector is fundamentally asymmetric in time and shows an observer-relatedness which may explain the double interpretation of the state vector as a representation of physical states as well as ofinformation about physical states.
The concept of relevance being used in all statistical theories of irreversible thermodynamics is demonstrated to be based on the same observer-relatedness.
Quantum theories of irreversible processes implicitly use an objectivized process The conditions for the reduction are discussed, and it is concluded that the final subjective observer system may be carried by a space point.

Entanglement in Philosophy of Physical Science. Attaching laminar, pedicled mucous membrane flaps to the nasal septum adjusts this dysfunction [ ].
The extremely irritating crust formation lasts for at least days [ ]. Further possible consequences are synechiae, septum perforations, burns or mechanical skin damage at the nasal vestibulum caused by drills and other instruments [ 42 ], [ ].
In a rather aggressive mode of preparation or when electrosurgical measures are applied in the maxillary sinus, an injury of the infraorbital n.
Bony dehiscences in the channel of the infraorbital nerve increase the risk of such a complication. As a consequence, facial sensibility is affected postoperative [ 76 ], [ ] Figure 5 Fig.
The same applies to the alveolar nerves. In justified individual cases of endonasal procedures, a complementary, localized transoral puncture of the maxillary sinus is recommended in order to remove hyperplastic mucosa in hidden anatomical areas, e.
In an adverse case, a branch of the infraorbital n. A relatively safe location for a complementary puncture is the intersection of two reference lines, i.
In transpterygoid rhino-neurosurgical approach, amongst others, the maxillary or the vidian n.
Past references depict single cases of severe orbital complications of vidian neurectomy. Recent literature only reports occasional cases of e.
Concerning the orbital haematoma, the slowly developing, venous hematoma is distinguished from the comparatively fast evolving arterial hematoma [ ].
The incidence of orbital hematomas is around 0. With right handed surgeons, orbital complications are supposed to occur more often on the right side, whilst other authors report a preference of the opposite side [ ], [ ].
A threatening venous bleeding is mostly observed with a delay, i. It is safe to assume that an accumulation of 5 ml of blood can already lead to a dangerous intraorbital increase in pressure, causing a loss of vision.
Therefore, even in case of seemingly slightly developed orbital hematomas, vision must be controlled repeatedly.
A simultaneous control of color vision is recommended — here, restrictions occur in a relatively early stage [ 76 ], [ ].
As a basic principle, cooling compresses are applied and the top end of the bed is raised [ ]. In case of threatening development, an emergency ophthalmic consultation is recommended.
Nasal packing is removed and the intraocular pressure is measured. The digital ocular massage is recommended various times in literature; it is, however, contraindicated in patients with illnesses of the bulbus and is debatable even in patients without a special ophthalmological anamnesis see below.
Further conservative treatment and possibly surgery as therapy of threatening venous hematoma is identical to the therapy for arterial bleeding [ ], [ ].
The retrobulbar hematoma as an arterial bleeding with a swift increase in intraorbital pressure is dreaded Figure 6b Fig. It appears intraoperatively and often even with delay, e.
Literature points out rare cases of a hematoma occurring hours later — for outpatient surgery, this has to be taken into consideration [ ].
Patient revealing major right-sided intraorbital hematoma in the course of ethmoidectomy. Lateral canthotomy and also inferior canthoysis have been performed.
Consequently a progressive proptosis with chemosis, pain, congestion of the conjunctival vessels and, eventually, ecchymoses or subconjunctival bleeding develops.
During palpation, a distinct resistance of the orbital tissue is felt and an increased intraocular pressure is noticed. Ocular motility is disturbed and the pupil reaction is pathological in side comparison, reduced or absent pupil reaction , resulting in visual field loss and loss of vision.
The orbital hematoma is a clinical diagnosis. It is not necessary to wait for a radiological confirmation [ ]. The most frequent cause is an injury of the anterior ethmoidal a.
Alternatively, the blood vessel is pulled out of its bed at the base of the skull, together with the onset of the vessel inside the orbit [ 82 ].
A similar event rarely occurs in the posterior ethmoidal a. There is a risk of blindness, though the pathogenesis is not completely clear: A pressure-related occlusion or a spasm of the ophthalmic or the central retinal a.
Other mechanisms are a blockage in the blood flow of the posterior ciliary arteries, caused by pressure or tension. The increased intraorbital pressure is most likely to produce an effect upon the venous system [ 76 ], [ ], [ ].
According to literature, in case of imminent loss of vision, a maximum duration of about 90 minutes remains until definite amaurosis. This basically depends on the ischemic tolerance of the retina [ 68 ], [ ], [ ], [ ], [ ], [ ], [ ], [ ], [ ], [ ].
A pressure-related interruption of the axonal transport in the optic n. In animal testing, slightly longer durations — about minutes were determined for the retina [ ], [ ].
Individual factors among others, a preexisting subclinical vasculopathy and anatomical factors can generally strongly modify the tolerance of the organism in regard to an increase in orbital pressure [ ].
The dynamics of the increase in pressure may also play a role [ 76 ]. As animal testing for orbital hematoma cannot be easily standardized, it is sometimes problematic to transfer the scientific findings to humans [ ].
Sinus surgeons should have a clear action-algorithm in the case of an orbital hematoma. In principle, there is no solid proof of effectiveness regarding conservative treatment.
Analogies from traumatology form the basis for the recommendations, partly any effect is denied [ 71 ], [ 82 ], [ ], [ ], [ ]. The regimes are variable, e.
Partly acetazolamide is prescribed in a lower dose or administered for longer periods — mg i. In individual cases, the therapy with cortisone is based on other substances e.
The indication for a surgical approach is often discussed in literature on the basis of an objective measurement of the intra-ocular pressure IOP [ ], [ ].
However, in daily routine the indication mainly takes place clinically, the pressure conditions can be estimated via comparative bilateral palpation [ ], [ ], [ ].
With individual differences, the orbital pressure is approx. Generally surgery of the paranasal sinuses has no effect on the intra-ocular pressure [ ].
Emergency indication for canthotomy and cantholysis is assumed for an IOP above 40 mmHg [ ], [ ], [ ], [ ], [ ].
In different references, surgery is necessary if the intra-ocular pressure IOP is higher than the mean arterial pressure minus 20 mmHg [ ]. Lateral canthotomy results in a reduction of the intra-ocular pressure by approx.
An orbital decompression may cause an additional pressure reduction of 10 mmHg [ ]. With complementary measures e. Lateral canthotomy with cantholysis is an emergency procedure.
It is simple and every sinus surgeon should be able to handle it. The surgery can take place almost everywhere e.
At first a straight, small vascular clamp is placed from the lateral canthus towards the border of the bony orbit between the upper and lower eyelid and is compressed.
To restrict surgery merely to this horizontal incisure is not recommended by the majority [ ], [ ] — the inferior and, if necessary, the superior cantholysis should complement canthotomy.
The lateral inferior palpebral ligament between conjunctiva and external skin of the eyelid is identified during the inferior cantholysis.
The palpebral ligament is completely dissected in caudal direction — during this process, it is repeatedly identified by palpation.
The immediate release of the inferior eyelid is noticed when the forceps is held into place with a certain tension at the lower eyelid [ ], [ ], [ ], [ ], [ ], [ ].
Many authors suggest to perform the canthotomy [ ], [ ], [ ] followed by inferior cantholysis only. Others recommend an additional incisure of the upper palpebral ligament if the canthotomy with inferior lysis is not effective [ ], [ ], [ ], [ ].
It is important to consider that the effects of this procedure are limited in time [ ]. If the angle of this protrusion is less than degree, the eye is definitively at risk [ ] Figure 7 Fig.
As a rule, however, the wound is sutured with a delay of 2 to 5 days, e. For secondary reconstruction of the lateral palpebral ligament, the special anatomy of the anchorage of the lateral canthus must be considered [ ], [ ], [ ].
Regarding prognosis it is known from traumatological literature that the risk of permanent blindness with manifest retrobulbar hematoma with accompanied loss of vision is approx.
Vision recovery takes place within a time frame of approx. Prognosis for younger patients is better [ ].
As a consequence the intra-ocular pressure was raised up to a pressure level of 54 mmHg IOP. Canthotomy and inferior cantholysis reduced the pressure to 32 mmHg and there were no relevant permanent damages [ ].
In other cases, a paraffinoma may develop especially within the region of the eyelids after a sinus operation. In the event of a often minimal injury of the lamina papyracea with a often mild orbital haemorrhage and if a paraffinic nasal packing ointment strip or ointment is inserted into the nose the paraffin can be absorbed via the mucosal wound in individual cases and transported via blood into the soft tissue of the orbit, respectively eyelids.
In rare cases, the inflammation continues as sclerosing lipogranulamatosis or as orbital pseudotumour, in a rare case this may lead to the development of a sinogen orbital phlegmon.
Spontaneous, partial regressions are rare. Classic paraffinomas should not occur any longer due to modern types of nasal packing in use and due to tendencies to disclaim packing at all.
Despite this fact, appropriate casuistic case reports still exist [ ], [ ], [ ], [ ], [ ], [ ]. If the history of the patient does not include a sinus operation, differential diagnoses are, among others: Two special cases of a lipogranulomatous tissue reaction were reported 2 to 14 days following an endonasal sinus operation, where no oily material was inserted.
There was a palpable tumour of the eyelid, eye movement disorder and proptosis. The granulomas were externally removed by surgery and oral corticoids and also an antibiotic were administered.
Concerning pathogenesis, an intraoperative injury of the orbit with focal fat necrosis and a consecutive tissue reaction on extracellular fat were assumed [ ].
The treatment of paraffinomas is surgical excision. A complete resection is usually impossible because of the diffuse tissue infiltration [ ].
Myospherulosis is related to the paraffinoma. It corresponds to a foreign body reaction of the mucosa to ointments containing lipids. Typical aggregates of erythrocyte residuals are histologically found in the vacuoles.
Factors that predispose the development of myospherulosis are not yet clarified. Patients tend to present a higher rate of postoperative synechia leading to a high number of revision surgeries [ ].
Myospherulosis granulomas also may form within the area of the eyelid following sinus surgeries with intraoperative haemorrhage of the eyelids and perioperative use of nasal packing with ointment [ ].
The microanatomy of the pterygopalatine fossa and the sphenopalatine foramen plays an important role in sinus surgery [ ]. Further terminal branches of the maxillary a.
If the routine opening of the maxillary sinus in the middle nasal meatus is systematically enlarged in dorsal direction, up to the level of the posterior wall of the maxillary sinus, then, in individual cases, it will be necessary, for anatomical reasons, to cut through a branch of the sphenopalatine a.
Bleeding from the root of the sphenopalatine a. During extended surgical procedures in the area of the infratemporal fossa severe bleeding from the maxillary a.
Instructions to identify the sphenopalatine a. In rare cases, a pseudoaneurysm may form as a result of an injured sphenopalatine artery. It was discovered 13 days after sinus surgery took place, which is quite early.
The authors prefer embolization rather than targeted endoscopic treatment clipping of the maxillary a. When entering the sphenoid sinus, the surgeon encounters the septal branch of the sphenopalatine a.
In the area of the anterior wall of the sphenoid sinus, it is mostly divided into three branches which supply the nasal mucous membrane [ ].
Within the scope of ENT routine surgery, an electrosurgical handling of this vessel is possible without any complication.
In case or repeated perioperative bleeding, angiography with selective embolization will only be performed in extremely rare cases [ ], [ ], [ ], [ ].
This applies especially for embolization in case of a treatment-resistant nose bleeding after routine sinus surgery when the source of bleeding does not evolve the internal carotid artery.
The exposure of radiation during embolization is relevant around 18 minutes in single series. The pharyngeal ramus of the sphenopalatine a.
It is a rare source of bleeding, e. The anterior ethmoidal a. In some of the cases the artery is located directly in the area of the osseous skull base, and more frequently ca.
According to anatomical studies, the anterior ethmoidal a. Arteries at risk are those with a larger distance to the skull base, arteries with bony dehiscences or those running within a ground lamella [ ].
Lateral injuries in the area of a funnel-shaped, medial-directed protrusion of the orbital wall can result in a threatening orbital hematoma, after retraction of the vessel stump see above.
It is situated in the level below the superior oblique m. If the artery has been injured and is bleeding into the ethmoidal cavity, a bipolar or monopolar coagulation is generally used to stop the bleeding [ ].
Many authors avoid the monopolar coagulation at the skull base due to possible secondary damage to the meninges [ ], [ ], [ ].
Alternatively, clips are suggested, which, however, are not always effective, due to anatomical reasons [ ], [ ], [ ]. With a diameter of ca.
The distance between the anterior and the posterior ethmoidal artery is approximately 10—14 mm and the distance from the latter to the optic nerve as well as to the anterior wall of the sphenoid is about 8—9 mm [ 12 ], [ ], [ ], [ ].
In a coronal CT, a tip-like protrusion of the medial orbital wall at the location of the posterior ethmoidal a.
As a general rule, the posterior ethmoidal a. A case report depicts a secondary orbital hematoma without significant proptosis, but with blindness [ ].
A subperiosteal orbital hematoma with visual impairment should be equally rare — symptoms were reversible after an emergency hematoma decompression [ ].
Uncomplicated hemorrhages in the posterior shaft of the ethmoid bone are treated with electrocoagulation [ ]. There are important neighbouring anatomical structures, especially the optic n.
The distance between the internal carotid a. Surgery performed in the sphenoid sinus requires sufficient preoperative diagnostic measures based on cross-sectional imaging [ 95 ], [ 97 ].
Particularly in the axial CT, significant anatomical details or variants are displayed: In principle, the carotid a. Dorsally, another prominence of the artery can occur in the lateral wall of the sphenoid sinus.
The bony canal of the artery is 0. The exact incidence rate of carotid injuries in paranasal sinus surgery is unknown.
According to literature, carotid artery injuries occur with a rate of 0. In the last mentioned operations, the risk increases considerably in revision surgery, after radiation therapy or if there is a tumor infiltration of the carotid [ ].
In routine paranasal sinus surgery, the most frequent defect site of the carotid a. In the scope of extensive rhino-neurosurgical procedures, further sources of bleeding, also from smaller branches of the carotid a.
As a matter of principle, every ENT surgeon and every clinic should therefore have clear action plan at hand for the emergency of an internal carotid a.
For paranasal sinus surgery, the following measures are recommended in case of an injury of the cavernous internal carotid a Revision surgery of the respective sphenoid sinus revealing a partly exposed coil green arrow: Additionally, the arterial injury can no longer be identified in the angiographic image, so that the otolaryngologist has to loosen the nasal packing and the angiography is repeated [ 95 ], [ ], [ ], [ ].
Due to the former reason the otolaryngologist should be present during neuroradiological diagnostics and intervention [ ].
In case of a very small lesion in the carotid vessel — provided appropriate local conditions, sufficient medical status of the patient and capabilities to pack the nose repeatedly — the surgeon should at first create an optimum access to the sphenoid sinus.
The placement of an autologous muscle graft or allogenic material is recommended. This construction is fixed with fibrin glue and is tightened with packing.
Alternatively, under favorable conditions, a specific vessel clip may be used [ 97 ], [ ]. Occasional reports point out that such a supply was permanently successful preserving the arterial circulation [ 96 ].
For this reason an angiography is indicated postoperatively [ 95 ], [ 97 ], [ ], [ ], [ ], [ ], [ ], [ ], [ ].
In case of an aneurysm secondary neuroradiological treatment is performed. During a primary neuroradiological intervention after an accidental lesion of the carotid a.
Here, specific complications, such as a vessel dissection, thrombosis, embolism or a vessel perforation have to be kept in mind.
Balloons can get displaced and then may increase the risk of new bleeding. Postoperatively, patients with vessel stents receive anticoagulant drugs Clopidogrel, ASS mg [ 95 ], [ ], [ ], [ ], [ ], [ ], [ ].
Within the first 24 hours after the neuroradiological intervention, a CCT control should be performed. Later on a control angiography should take place [ ], [ ].
The defect site in the sphenoid sinus should be covered secondarily, for example with fascia [ 95 ] Figure 9 Fig. Hemorrhages from the cavernous sinus are mostly much less demanding.
Bleeding is interrupted by placing hemostatic material directly and applying smooth pressure. The material is inserted, covered with neuro-cotton wool and lightly pressed [ ].
In principle, hemostasis during rhino-neurosurgical procedures as well as during sinus surgery is based upon bipolar coagulation, compression, nasal packing or ligature as well as upon the application of clips.
However, in case of an exposed dura, a sufficient compression is not always possible and an external nasal packing additionally creates the risk of bleeding in intracranial direction.
Immediately after the incidence, a second suction is introduced into the operating field and the endoscope is directed to a protected place; if applicable, equipped with a rinsing and suction device.
In favorable individual cases, it might be possible to direct the jet of blood into the suction, to display small lacerations of the artery and to fuse and glue them by means of bipolar coagulation [ ], [ ], [ ].
The use of an intraoperative Doppler is recommended as a measure of prevention [ ], [ ]. If an ordinary hemostasis is not successful, further nasal packing is applied and an emergency transfer of the patient to the neuroradiological ward is carried out [ ].
The prognosis of an injury of the carotid a. An injury of the carotid a. This condition is treated through neuroradiological intervention [ 89 ], [ ], [ ].
Even after a successful occlusion-test complications following the definitive occlusion cannot be excluded [ 95 ], [ 97 ], [ ], [ ].
In this regard, very different frequencies are found in literature: The average bone thickness in the direction of the sphenoid sinus is 0.
Hence it is even more important to look out for a history of previous eye defects preoperatively. Perioperatively, this damage might only appear to deteriorate, e.
As a consequence, unnecessary emergency measures might be taken, even medico-legal problems might arise [ ].
Perioperative blindness in paranasal sinus surgery occurs in case of a direct injury of the nerve, a drug-induced interruption of local blood supply or a hematoma in extremely rare cases also by an emphysema, see above or in case of damaging the central nervous system, as, for instance through meningitis [ 76 ].
Direct mechanical damage to the optic nerve is only reported in exceptional individual cases [ ], [ ]. Here, during removal of the covering bone, the nerve can be damaged or destroyed in the cranial, lateral wall of the sphenoid sinus [ ] or within the orbit [ ].
In other cases, injuries of the optic n. A case report of a severe, direct injury of the eyeball across the lamina papyracea caused by an electrosurgical tube without direct nerve damage seems to be exceptional [ ].
In case of an injury of the optic n. Compared with direct lesions, indirect injuries of the optic nerve caused by a retrobulbar hematoma occur more frequently [ 83 ], [ ].
Loss of vision as a complication of adrenaline-soaked e. Adrenaline resorption with consecutive spasm of the vessel network around the optic n.
After every postoperatively noticed or supposed visual reduction, an ophthalmological emergency consultation should occur.
MRI is strongly recommended [ ]. After mechanical injury of the nerve, collateral damage has to be searched for, e.
If the optic n. Even if nerve continuity is preserved, the immediate treatment of the perioperative visual reduction is problematic.
The regimen is individualized and is under ophthalmological guidance. If neurapraxia or a hematoma is suspected, a high dose corticosteroid treatment is followed out e.
The concept is aligned to the treatment of traumatic optic neuropathy — evidence of which, however, still remains a subject of debate [ 71 ].
Traumatology and neurology provide some experimental evidence to suggest that corticosteroids may also hinder the restitution of an optic nerve [ ], [ ], [ ], [ ], [ ].
In specific cases, decompression of the nerve may be discussed — however, its benefit has not been proven yet [ 12 ], [ 76 ].
Under certain, adverse conditions, the symptoms of an ischemic optic-neuropathy may appear within the scope of sinus surgery, a disease of which little is known.
In these rare cases, neither mechanical injury of the nerve has occurred nor has the lamina papyracea been damaged.
The exact pathogenesis is not yet known. The resulting loss of vision or visual field reduction emerges immediately or with a delay of several hours to days.
MRI displays a vaguely defined and swollen optic n. A decompression of the optic nerve does not always seem appropriate.
Administration of cortisone e. An immediate normalization of blood pressure and hemoglobin by means of transfusions seems essential [ ].
A case report described residual ethmoidal cells revealing opacification. An emergency revision surgery was performed with decompression of the orbit and periorbital incisure.
Additionally, high dose corticosteroid treatment Prednisolone mg intravenously and calculated antibiotic treatment was initiated. Within a period of 4 weeks the condition of the patient improved.
In another case, the optic n. These two cases were interpreted as a consequence of an infectious impairment of the optic n. In endonasal surgery of the paranasal sinuses, an impairment of the medial rectus m.
In general, these injuries result of a fracture of the inferior lamina papyracea with perforation, destruction or incarceration of the muscle.
The middle or posterior ethmoid is most at risk — as hardly any fat is situated between the muscle and the bony orbital wall [ 76 ], [ ], [ ], [ ].
In rare cases, there is a particular risk due to a congenital or posttraumatic bulge of the lamina papyracea with or without direct embedding of parts of the muscle [ ], [ ].
Other eye muscles are distinctly less often injured intraoperatively: The inferior rectus muscle may be damaged in surgeries involving the maxillary sinus and the superior oblique trochlea muscle may be lacerated in extended endonasal frontal sinus surgery with a drill for instance.
Injuries of the inferior oblique m. In the majority of cases, only one eye muscle is damaged, with a relevant orbital hematoma developing additionally in one quarter of patients.
Occasionally, however, severe combined damage affecting three muscles, for example, has been observed with additional bleeding, retinal damage or lesions of the optic n.
Generally 5 typical causes for a postoperative motility disorder of the eye may be distinguished:. Muscle tissue that is surprisingly evident in routine histologic specimens Figure 10 Fig.
In general, periorbital damage should be detectable intraoperatively by means of the bulbus pressure test [ ]. If, beyond that, intraoperatively suspected eye muscle damage occurs, an ophthalmologist should be notified and consulted immediately [ ], [ ].
With few exceptions, diplopia appears immediately after the operation as a result of the injury [ ]. All relevant findings should be submitted immediately for evaluation by means of imaging.
The clarification of an eye muscle injury with displacement or incarceration or the display of a contraction of the dorsal muscle parts most likely succeeds after complete sectioning with a contrast-enhanced MRI; evaluation is done in three planes.
At best, multipositional MR imaging might allow to draw conclusions about the contractility of the muscles. In the further course, a repeated MRI may also document stages of repair, as swelling of muscle tissue is followed by atrophy.
Other sources recommend a CT as initial diagnostic measure for all orbital complications, as differentiated analysis of the injury is hindered initially through hematomas and accompanying edema [ 71 ], [ 76 ], [ ], [ ], [ ], [ ], [ ].
Generally, the findings of CT and MRI correlate well with the ophthalmological functional examinations [ ]. Regarding treatment of acute, iatrogenic eye muscle damage, an early surgical intervention should be performed within 1 to 2 weeks, if a muscle was completely intersected or if an incarceration of tissue or a skewering of bone fragments into the muscle is suspected clinically or via imaging [ 71 ], [ ], [ ], [ ].
A reconstruction of the medial rectus m. In case of excessive destruction, a muscle transposition might be sought; alternatives are graft interpositions or specific suturing techniques [ ], [ ], [ ], [ ].
In order to exclude corresponding damage in revision surgery, aggressive orbital dissections should be avoided during further surgical therapy [ ].
Reconstruction of the medial orbital wall directed to the ethmoidal cavity, using alloplastic material, often cannot prevent a secondary, bothering scar formation [ ], [ ].
In individual cases, an immediate cortisone therapy is applied in an effort to minimize the inflammatory response of the orbital tissue [ 71 ].
In case of partial damage, literature recommends both an observant and an active approach [ ]. Contractures of the antagonists of damaged muscles can already be observed after 2 weeks.
Especially in cases of severe injuries, revision surgery performed before fibrosis begins to occur, i. In contrast, spontaneous improvements were observed within a period of three months after slighter neuronal, vascular or direct muscle damage [ 71 ], [ ], [ ].
By means of botulinum toxin injections into the antagonists of damaged muscles, diplopic images can be improved faster, a secondary contracture of the antagonist is prevented and the traction force applied to the damaged muscle is reduced.
For reasons which are not fully known, the injection can make a positive contribution to a long-term functional alignment of the extraocular muscles [ 76 ], [ ], [ ], [ ].
In appropriate cases, the injection is combined with a surgical muscle reconstruction [ ], [ ]. Other forms of impairment are treated conservatively in the beginning [ ].
If the muscle is only affected by bruising, neural or vascular damages, it may be justified to wait for 3—12 months [ 71 ], [ ], [ ].
Two to three months after a damage caused to the medial rectus m. In two thirds of cases, several operations will be necessary [ ], [ ]. Extremely severe damages of the ocular muscles and the orbital tissue have been reported after the use of the microdebrider [ 71 ], [ 76 ], [ ], [ ].
The medial rectus m. This may also occur without any prominent orbital injury. Often the surgeon is not even aware of the damage. The perforation in the lamina papyracea may be difficult to identify, even in postoperative imaging [ 17 ], [ 71 ], [ ], [ ], [ ].
In other cases, motility limitations can be distinctly higher than the damage seen at imaging. After injuries caused by the shaver, chances to reconstruct the medial rectus muscle successfully are rather limited [ ].
In rhino-neurosurgical operations, especially in the parasellar and suprasellar region, in the area of the cavernous sinus or the clivus, thermal injuries or transections may lead to injuries of the abducens n.
Frequently the oculomotor nerve recovers postoperatively from damages as long as the continuity of the nerve is preserved [ ].
For various reasons, a mydriasis can occur during paranasal sinus surgery:. In individual cases, pupil differences without pathological substrate can occur during anesthesia.
In a small percentage of the population, an observable anisocoria i. Under general anesthesia, the light reflex cannot be judged. Therapy with opiates e.
Fentanyl leads to miosis which, however, can decrease, due to an intraoperative sympathicus stimulus. Individual factors affect the size of the pupils during extubation; in some cases even, side differences, lasting about 20 minutes may occur during this process.
Based on the described circumstances, a number of recommended precautions can be deduced:. During the operation, the eyes should always remain free from textile covering.
The scrub nurse should get used to control the eye from the outside while surgery continues in the inside of the nose. Hence complications are indicated by a passive concurrent movement of the globe and can be noticed early.
Generally, a serious acute narrow angle glaucoma can be triggered by sympathomimetica in predisposed patients [ ].
The placeholder had perforated the dorsal orbital apex and caused permanent changes in the pupils. Even an emergency revision surgery with removal of the foreign material did not result in an improvement [ ].
Paranasal sinus surgery, in the broader sense, with extensive removal of the mucosa can cause a scarred distortion of the entire ethmoidal cavity in adults, combined with a medialization of the lamina papyracea.
These transformations can be identified by postoperative imaging and may be associated with a subclinical enophthalmos [ ], [ ]. In children, after paranasal sinus surgery, a postoperative hypoplasia of the maxillary sinus with no external changes was described radiologically [ ].
After unilateral ethmoidectomy in a pediatric case of an imminent orbital complication, merely a minimal facial asymmetry was visible in the postoperative CT [ ].
A similar case of a postoperative scarred stenosis of the maxillary ostium and a secondary maxillary sinus atelectasis with postoperative enophthalmos 3 mm was also observed in an adult patient [ ].
