Sublabial-endonasal approach to the sella turcica.

In this paper the authors describe the sublabial-endonasal-transsphenoidal approach to the sella turcica, a modification that combines elements of the sublabial-submucosal-transseptal approach and the endonasal approach. It provides a midline, or near midline, trajectory, wide exposure of the sella, and secure speculum placement on the osseous edge of the pyriform aperture, while avoiding dissection of the nasal mucosa, and it can be used for microscopic and endoscopic surgery.
