Nasal septum after sublabial transseptal transsphenoidal pituitary surgery.

Transseptal transsphenoidal approach to the pituitary fossa is a well-described and effective procedure. This article relates our experience with this procedure with specific emphasis on the nasal septum, both before and after surgery. It has been our experience that this surgery has minimal local complications in the nose and it would appear to improve septal alignment with subjective improvement in nasal function as reported by the patient. A total of 55 patients undergoing a sublabial transseptal transsphenoidal approach to the pituitary fossa were included in this study. All other approaches to the pituitary gland were excluded. Visual changes and headaches were the most common presenting symptoms, occurring alone or in combination in 28 (51%) patients. Twelve (22%) patients reported symptoms of nasal obstruction before surgery and only one (2%) after surgery. A moderately or severely deviated septum was noted in 30 (54%) patients before surgery and 4 (7%) patients after surgery. The septum was straight in 21 (38%) patients before the procedure and 49 (89%) patients after the surgery. Sinusitis developed in two patients, and one patient subsequently required surgery. No synechiae or septal perforations were noted.
