Intranasal approach to the sella turcica.

A transseptal approach to the sella turcica is described which is entirely intranasal and avoids the sublabial incision. The first incision is unilateral along the caudal edge of the septum, and the second incision is made across the base of the nasal columella. This allows the speculum to open the width of both nasal chambers, giving adequate exposure. The septal cartilage is either preserved or resected except for a caudal strut. The difficult dissection of mucosa from the nasal floor and maxillary crest is avoided. This technique is rapid and straightforward and results in a cosmetically acceptable scar.
