RATIONALE Mucocele is a disease lined primarily by epithelium, and occurs mainly when the sinus ostium is obstructed. PATIENT CONCERNS We report a case of a 37-year-old man who presented with painless proptosis of the right eye and diplopia. DIAGNOSES The preoperative finding was mucocele of the ethmoid sinus. INTERVENTIONS We performed endoscopic sinus surgery, which included uncapping o...

The sphenoid sinus occupies a central location in transsphenoidal surgery (TSS). It is important to identify relevant anatomical landmarks to enter the sphenoid sinus and sellar region properly. The aim of this study was to identify anatomical landmarks and their value in single-nostril endonasal TSS. A retrospective study was performed to review 148 cases of single-nostril endonasal TSS for pi...

Sphenoid sinus lesions can present with a multitude of symptoms/signs including ophthalmic disturbances. We describe a total of five patients, of which two had mucoceles and rest three had fungal infection. Ophthalmic symptoms/signs were the ones we were really interested in. We also present one case which had isolated sphenoid fungal sinus. We also give details of their presentation, investiga...

BACKGROUND AND PURPOSE The sphenoid sinus is rarely implicated as a site of spontaneous CSF fistula. We undertook this study to evaluate the potential etiopathogenesis of spontaneous CSF fistula involving the sphenoid sinus and to review the imaging findings. METHODS We retrospectively reviewed the imaging findings of 145 cases of CSF fistula from our departmental archives (August 1995 throug...

The aim of this report is to investigate the pathogenesis and surgical treatment of encephalocele located in the sphenoid sinus and presented with spontaneous rhinorrhea. The data of a patient with sphenoid sinus encephalocele was analyzed in association with the review of literature. The patient admitted to our clinic with rhinorrhea from the left nasal cavity. Cranial magnetic resonance imagi...

BACKGROUND Sphenoid sinus is the most inaccessible paranasal sinus, enclosed within the sphenoid bone and intimately related to numerous vital neural and vascular structures. Anatomic variation of the sphenoid sinus is well documented and may complicate surgery in such a place. OBJECTIVE To outline the surgically risky anatomic variants of the sphenoid sinus as well as the variable relationsh...

BACKGROUND AND PURPOSE The termination of the superficial middle cerebral vein is classically assimilated to the sphenoid portion of the sphenoparietal sinus. This notion has, however, been challenged in a sometimes confusing literature. The purpose of the present study was to evaluate the actual anatomic relationship existing between the sphenoparietal sinus and the superficial middle cerebral...

BACKGROUND The anatomical structures of anterior area of sphenoid sinus are observed by CT reconstruction of radiographic images in some studies. However, the detailed anatomic information of the extended transsphenoidal approach is still incomplete. METHOD Fifteen cases (30 sides) of adult cadaveric skulls and 20 cases (40 sides) of bleached adult dry skulls were observed and measured under ...
