conclusions an extremely rare condition, a spontaneous intracranial pneumocephalus with skull base defect origin could be considered as a possible diagnosis in patients with sudden and severe headache. we can safely conclude that medical treatment and close follow-up is an effective mode of therapy in this patient. introduction spontaneous pneumocephalus without any pathological condition is ve...

Fungal infections of the nose and paranasal sinuses are frequent in this part of the world. One aspect of the increased frequency is the improved clinical, radiological and pathological diagnostic methods that are now available. Aspergillus is the commonest infecting fungus of the nose and the paranasal sinus. It is mainly a saprophytic spore producing fungus and can cause invasive and non-inva...

BACKGROUND This study examined the relationship between the superior turbinate and natural ostium of the sphenoid sinus, as seen during the endoscopic endonasal transsphenoidal approach (EETSA) for sellar lesions and described how to enter the sphenoethmoid cell safely for complete exposure of the sellar floor, including adjacent vital structures such as the prominence of the optic nerve and ca...

STATEMENT OF THE PROBLEM The sphenoid sinus is a common target of paranasal surgery. Functional endoscopic sinus surgery is likely to endanger the anatomic variations of vital structures adjacent to the sphenoid sinus. PURPOSE The aim of this study was to determine the variations of sphenoid sinus and the related structures by using cone-beam computed tomography (CBCT). MATERIALS AND METHOD...

BACKGROUND Sphenoorbital meningiomas are surgically challenging because of their nature to extend to adjacent structures. Here, we describe a case of recurrent sphenoorbital meningioma extending into the sphenoid sinus, pterygopalatine fossa, and infratemporal fossa, which was resected using combined simultaneous transcranial and endoscopic endonasal approaches. CASE DESCRIPTION A 62-year-old...

OBJECTIVES To evaluate the pathologic conditions, preoperative evaluation, treatment, and clinical outcomes associated with sphenoid sinus disease. DESIGN Retrospective study. SETTING Tertiary university-based referral center. PATIENTS All patients with isolated sphenoid sinus disease managed surgically or in which surgery was considered a primary treatment option. MAIN OUTCOME MEASURES...

INTRODUCTION The paranasal sinuses mucoceles are benign expansive cystic lesions that occur rarely in the sphenoid sinus and contain mucous material enclosed by cylindrical pseudostratified epithelium. OBJECTIVE To report one case of sphenoid sinus mucocele that occurred with headache and was submitted to surgical treatment through endonasal endoscopy approach. CASE REPORT 59-year-old male ...
