Transsphenoidal canal (large craniopharyngeal canal) and its pathologic implications.
نویسندگان
چکیده
A vertical conduit in the basisphenoid extending from the floor of the sella to the undersurface of this bone was observed in two children. There was no associated nasopharyngeal mass. A review of the literature on this defect and related subjects suggests a close relation between this lesion and transsphenoidal meningoencephalocele.

We reviewed a series of craniopharyngeal canals to determine a system of classification that might better our understanding of this entity, highlight the range of associated pathologic conditions, and optimi...

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...
