Background This study was performed to determine the variations in the branching pattern of
the sphenopalatine artery medial to the crista ethmoidalis. Seventy-seven cadaver head …

Objective We investigated the surgical anatomy of the sphenopalatine artery. First, the
location of the sphenopalatine foramen on the lateral nasal wall and the pattern of the main …

Objectives: Understanding the endoscopic locations of the anterior and posterior ethmoid
arteries is important during endoscopic sinus or endoscopic skull base procedures so that …

Posterior epistaxis is a significant medical problem that can be challenging to treat.
Endoscopic surgery could potentially reduced operative time and patient risk; however …

Background Refractory posterior epistaxis is a challenge for otolaryngologists. Most
algorithms for managing this condition ultimately call for interrupting the arterial blood supply …

Background Sphenopalatine artery (SPA) ligation or cauterization stands to be one of the
most common management options of refractory epistaxis. Ramification pattern of SPA as it …

Aim: This study investigated the extent to which the anterior ethmoidal artery and anterior
ethmoidal foramen could be reliably identified on routine coronal sinus computed …

The anatomy of the sphenoid sinus, as it relates to endoscopic sinus surgery, was studied in
93 cadaver heads (186 sphenoid sinuses) using endoscopic dissections as well as sagittal …

A better understanding of the pathogenesis of chronic sinus disease has led to an increased
performance of endonasal sphenoethmoid surgery. Approaching the sphenoid sinus via this …

Advances in surgical techniques and instrumentations, utilization of the imaging tools, and
understanding the regional anatomy have served to make functional operations with less …
