Endoscopic anatomy of sphenoid sinus for pituitary surgery.
Endoscopic endonasal transsphenoidal approach to the sellar region yields an alternative to classical microsurgical approaches. Endoscopes provide images that differ from microscopic view. This study aimed to highlight surgical landmarks and their anatomical relationships for pituitary surgery through endoscopic perspective. Ten sides of five adult cadaveric heads with red-colored latex injecte...
متن کاملEndoscopic anatomy of the sphenoid sinus.
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 sections. The relationship of the sphenoid sinuses to the carotid artery, optic nerve, floor of sella turcica, as well as other important structures, were verified and discussed. The recesses of the sinus as well as...
متن کاملThird ventricle herniation into the sphenoid sinus following endoscopic transnasal transsphenoidal fenestration of Rathkes cleft cyst.
Rathke cleft cyst (RCC) is an uncommon albeit benign sellar lesion with an incidence rate of between 2 to 33%. RCCs are usually asymptomatic except in the large cases whit suprasellar extension. We herein describe a unique case of RCC, which presented with severe visual loss owing to massive herniation of the optic chiasm and third ventricle down into the sphenoid sinus through a small 8 x 8 mm...
متن کاملEndoscopic transsphenoidal resection of sellar tumors with conchal sphenoid sinus: A report of two cases
A conchal non-pneumatized sphenoid sinus was previously considered to be a contraindication to the endoscopic transsphenoidal route to the sella due to its small sellar floor and poor anatomical landmarks, such as the optic nerve canal, opticocarotid recess and internal carotid arteries canal. The present study aimed to investigate the methodology and characteristics of the endoscopic transsphe...
متن کاملThe anatomical relations of the sphenoid sinus and their implications in sphenoid endoscopic surgery.
Alongside the past development of endoscopic sinus surgery, knowledge about the anatomy of the sinuses has become crucial for surgeons. The sphenoid sinus is one of the most variable of all sinuses. Its relations to vital vascular and nervous elements make its approach a challenge for endoscopic surgeons. These relations include the internal carotid artery, the optic nerve, the pituitary gland,...
