INTRODUCTION Spontaneous pneumocephalus without any pathological condition is very rare. We described a patient with spontaneous pneumocephalus probably arising from the relatively enlarged air-filling sphenoid sinus. CASE PRESENTATION A 51-year-old woman admitted Imam Reza Hospital, Mashhad, Iran with a sudden onset of severe headache and nausea without any neurological deficit. Brain comput...

We describe a practical technique of superior turbinectomy followed by posterior ethmoidectomy as a less invasive procedure for two-surgeon technique on endoscopic endonasal transsphenoidal surgery. After identification of the superior turbinate and the sphenoid ostium, the inferior third portion of the superior turbinate was coagulated and resected. This partial superior turbinectomy procedure...

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...

Lymphoma is usually the malignant tumor which originates from lymph node or lymph-tissues. The nasal cavity and paranasal sinuses are rare primary sites for lymphoma. In the paranasal sinuses, lymphoma of maxillary sinuses is the most common, ethmoidal sinuses is more than that of frontal sinuses, sphenoid sinuses is the least. The most common presenting symptoms are nasal obstruction, rhinorrh...

A concha non-pneumatized sphenoid is considered to be a contraindication for the transsphenoidal resection of a pituitary adenoma. Specifically, this anatomical variation makes it difficult to approach the sella turcica. However, in this report, an intra-operative navigational system was used as a guide to access the sella through the sphenoid sinus. This procedure was found to be both reasonab...

SUMMARY A 73-year-old man was admitted with invasive aspergillus of the sphenoid sinus. Endoscopic debridement of the sphenoid sinus was complicated by rupture of a mycotic cavernous carotid artery aneurysm with severe epistaxis. The aneurysm was closed emergently by endovascular coil placement. Subsequently, the mycotic aneurysm extended intradurally and caused fatal subarachnoid hemorrhage. T...

INTRODUCTION The type of endoscopic approach chosen for vidian neurectomy can be specified by evaluating the vidian canal and the surrounding sphenoid sinus structures. OBJECTIVE The variations and morphometry of the vidian canal were investigated, focusing on the functional correlations between them which are crucial anatomical landmarks for preoperative planning. METHODS This study was pe...

Aim: This study aimed to find the effect of preoperative tumor embolization and transnasal endoscopic excision of a sphenoid sinus angiofibroma on the postoperative outcome. Case Report: A thirteen year old male presented to the Outpatient ENT Department of a tertiary care centre, with a history of recurrent left-sided spontaneous painless epistaxis since one year. Diagnostic Nasal Endoscopy sh...

OBJECTIVE To describe the clinical features of invagination of the sphenoid sinus mucosa (ISM) and compare them with other similar cases using a visual analog scale (VAS) to assess the various nasal symptoms and to discuss its clinical significance and means of prevention. STUDY DESIGN Retrospective chart review at a tertiary referral center. METHODS Between 2010 and 2015, 8 patients who ha...

One type of congenital intrasphenoidal meningoencephalocele is remnant of lateral craniopharyngeal (Sternberg's) canal. We present a case of a 23-year girl with 10-month history of right side CSF rhinorrhea. CT scan, MRI revealed congenital meningoencephalocele and CSF leak from middle fossa to right side of sphenoid sinus, and there were bony defects at the floor of the anterio...
