Last revised by Calum Worsley on 20 Jan 2023

The tuberculum sellae is the ridged process of the sphenoid bone which forms the anterior wall of the sella turcica.

Gross anatomy


The tuberculum sellae forms the anterior wall of the sella turcica, which houses the pituitary gland. It is an elongated ridge located immediately posterior to the chiasmatic groove, hence is related to the optic chiasm and anterior portions of the optic tracts. Laterally are the optic canals and posterolaterally lie the anterior clinoid processes.
