Abstract Background Surgery is often indicated for definitive biopsy or as the primary treatment modality pediatric skull base lesions. Traditionally, open surgical approaches were utilized to address pathology. However recently, expanded endoscopic sinus surgery has been a minimally invasive approach addressing pathology in population. Purpose This review provides an overview of current litera...

PURPOSE In adults, sphenoid sinus agenesis is an extremely rare anomaly. The objective of this study was to investigate the prevalence of sphenoid sinus hypoplasia and agenesis using dental volumetric computed tomography (DVCT) in a population of Turkish individuals. MATERIALS AND METHODS DVCT scans in the axial, coronal and sagittal planes of the sphenoid sinus of 384 patients were examined ...

A transcranial approach in combination with a transpetrosal setting has been the mainstream of surgical treatment of cholesterol granulomas in the petrous apex. However, endoscopic endonasal surgery has become a choice of treatment for these lesions with recent advancements in surgical techniques and instruments. We report a successful case of cholesterol granuloma managed with endoscopic endon...

OBJECTIVE The purpose of this study was to present the morphometry and pneumatization of the sphenoid sinus in detail for the neurosurgeon for transnasal approach to the hypophyseal tumors and especially for functional endoscopic sinus surgery. METHODS One hundred and eighty midsagittal magnetic resonance images, 48 bones and 29 hemi-sectioned cadaveric heads obtained from Ege University, Fac...

Background: En plaque sphenoid wing meningioma is morphological unique in comparison with other intracranial meningiomas, characterized by a carpet-like usually small soft tissue component which invade the dura and extensively involve the bone specially the sphenoid wing and orbit causing significant hyperostosis. Patients & Methods: A retrospective analysis of the clinical data, neuro-radiolog...

A 69-year-old man consulted our department regarding further examination because abnormal venous ectasia of the basal vein of Rosenthal (BVR) was accidentally found on magnetic resonance imaging. Angiography revealed a dural arteriovenous fistula (DAVF) in the left sphenoid wing; the fistula was supplied by the ophthalmic artery and the middle meningeal artery. Venous drainage from the fistula ...

Delayed posttraumatic cerebrospinal fluid rhinorrhea (CSFr) without meningitis is considered to be relatively rare. However, even years after trauma, recurrence or delayed onset of CSFr and meningitis due to CSFr are possible. In this article, a case of delayed CSFr from the sphenoid sinus without meningitis three years after the transfacial gunshot wound is reported. Plain high-resolution comp...

INTRODUCTION When an expanded endonasal transsphenoidal surgical approach is performed, intrasphenoid septations must be completely resected. If these structures are close to the internal carotid artery (ICA), then their manipulation might cause vascular injury. OBJECTIVE The objective of this study is to describe the frequency of intrasphenoid septations in the internal carotid artery protub...

Introduction  The sphenoid sinus (SS) has a high variability; its anatomical relations and variations must be well understood prior to the expanded endoscopic surgery (EES) at the skull base via the endonasal transsphenoidal approach. A feared complication is injury to the internal carotid artery (ICA). Objective  To evaluate the anatomic variations of the SS and its relationship to the ICA usi...

OBJECTIVE To clarify the three-dimensional anatomical features of the sphenoid sinus and its surrounding structures as are relevant to performing an endoscopic sphenoidotomy. METHODS Various dimensions of 224 CT images of the sphenoid sinus and surrounding structures from 122 Japanese adult patients were measured using the multiplanar reconstruction technique. RESULTS The mean distance from...
