1/326. Neurosurgical aspects of sphenoid sinus mucocele.

    The aetiological spectrum of sphenoid sinus mucocele includes congenital anomaly, trauma, infection, allergy and surgery of the sphenoid sinus. Enlargement of the mucocele, even with a short history, can result in progressive expansion of the sinus and extension of the lesion into the pituitary fossa, the suprasellar region, nasopharynx, orbits, clivus or ethmoid air cells. It is a benign cystic lesion with an excellent prognosis when treated appropriately. Generally, these lesions are managed by an ear, nose and throat surgeon, but when there is extension into the sellar and parasellar (especially suprasellar) regions they are managed by the neurological surgeon. sphenoid sinus mucocele should be considered in the differential diagnosis when there is suspicion of a cystic lesion in these regions. Three cases of large sphenoid sinus mucocele are presented, with discussion on their neurosurgical management and a review of the literature.

2/326. frontal sinus pneumocele. A case report.

    A pneumocele refers to an aerated sinus with either focal or generalized thinning of the bony sinus wall. Although the pathogenesis of a pneumocele is not yet known, it is presumed that increased intrasinusal pressure, due to a one-way valve between the nasal cavity and the affected sinus, is responsible for this condition. A 37-year-old man with frontal bossing, who underwent surgery for cosmetic reasons, is presented.

3/326. Concha bullosa pyocele--undiagnosed for 3 years.

    We report a rare case of post-traumatic concha bullosa pyocele in a diabetic teenager that has gone undiagnosed for 3 years. The clinical findings, radiological features and management are discussed. The literature is reviewed.

4/326. Non-randomized comparison of surgical modalities for paranasal sinus mycoses with intracranial extension.

    Mycotic infections of paranasal sinuses are frequently reported in southern asia. aspergillus and Mucor species are the predominant ones. Intracranial extension of paranasal sinus mycoses is a difficult problem to manage. We report 18 cases of paranasal sinus mycoses with intracranial extensions. The commonest manifestations were nasal discharge (67%), nasal obstruction (50%), ocular symptoms such as proptosis (44%), telecanthus (39%) and ophthalmoplegia. Computerized tomography scans were found to be quite informative regarding the nature and extent of the disease (100% sensitivity and 78% specificity). A combined intracranial-extracranial approach (six cases) gave a distinct advantage over only adopting an extracranial approach (12 cases). A 17% incidence of CSF leak was noted by adopting only an extracranial approach as well as a recurrence in four cases out of the 12 that were treated using this method (P < 0.05). A slight increase in morbidity was associated with the combined intracranial-extracranial treatment, but no recurrence or significant complications were noted in this approach.

5/326. Acute angle closure glaucoma precipitated by intranasal application of cocaine.

    We describe a patient who developed acute angle-closure glaucoma following the application of topical intranasal cocaine. A 46-year-old woman underwent an elective antral washout under general anaesthesia and with local application of 25 per cent cocaine paste to the nasal mucosa. Twenty-four hours post-operatively the patient developed sudden painful blindness which was found to be due to acute glaucoma. cocaine with its indirect sympathomimetic activity causes mydriasis, that can precipitate acute angle-closure glaucoma in predisposed individuals with a shallow anterior chamber. Although the incidence is rare, otolaryngologists need to be aware of this potential complication.

6/326. Rhinosino-orbital mucormycosis causing cavernous sinus thrombosis and internal carotid artery occlusion: radiological findings in a patient with treatment failure.

    The authors describe a case of rhinosino-orbital mucormycosis with cavernous sinus thrombosis in association with internal carotid artery occlusion diagnosed by use of computerized tomography (CT) and magnetic resonance imaging (MRI). Cranial CT is a useful imaging tool in the diagnosis of rhinosinal invasive fungal disease and MRI offers excellent aid in the detection of intracranial extension. early diagnosis and rapid institution of surgical debridement and antifungal therapy is the rule of thumb in treating this disorder. In our patient, surgically inaccessible bone lesion and involvement of the central nervous system are taken as major causes for his grave outcome. In addition, failure to advance appropriate amphotericin b dosage may also make the infectious process uncontrollable in this patient.

7/326. Inferior concha bullosa--a radiological and clinical rarity.

    Two cases of inferior concha bullosa (ICB) are reported. The condition was bilateral in one patient and unilateral in the other. Unilateral ICB was associated with marked septal deviation. The diagnosis was made in patients being investigated for chronic rhinosinusitis. ICB is diagnosed by computed tomography (CT) of the sinuses in the coronal plane. It may also be seen in axial views.

8/326. A rare case of pneumosinus dilatans of the frontal sinus and review of the literature.

    Pneumosinus dilatans is a rare condition of unknown etiology in which there is enlargement of the paranasal sinuses by air, with extension beyond the normal boundaries of bone. The authors present a case of pneumosinus dilatans of the frontal sinus and review the literature.

9/326. Paranasal mucous cyst: a rare finding following septorhinoplasty.

    Postoperative niucous cysts of the facial soft tissue are a rare complication after septorhinoplasty. We present a case of postseptorhinoplasty mucous cyst with a paranasal localisation. According to the literature available to us this localisation is extremely rare and has not been described before. Aetiology and possibilities to decrease the risk of such complications are discussed.

10/326. Sphenoidal sinus mucocele after transsphenoidal surgery for acromegaly.

    This report concerns one case of a sphenoid sinus mucocele occurring 17 years after transsphenoidal surgery for acromegaly. In 1979, a 51-year-old man was successfully operated by the transnasal transsphenoidal approach for a growth hormone (GH) adenoma 1 cm in diameter. In 1996, the patient was hospitalized for headaches and diplopia. He presented a loss of right visual acuity with paralysis of the right oculomotor nerve. The basal GH level was normal with a satisfactory decrease after oral glucose ingestion. Pituitary sellar radiography showed a disappearance of the posterior clinoid while magnetic resonance imaging revealed the existence of a bilocular, circular, homogeneous lesion of the sphenoid sinus 3 cm in diameter with a posterior and lateral extension. The diagnosis of mucocele was confirmed by surgical treatment, allowing drainage of the mucocele through a transsphenoidal approach. The drained material was composed of sinus epithelium containing many polynuclear and resorptive cells. Postoperatively, the symptoms decreased dramatically, leading to full recovery of visual function and disappearance of the headaches. Apart from the tumor recurrence, the mucocele of the sphenoid sinus can be evoked as a possible long term complication of transsphenoidal surgery for pituitary adenoma.
