Abstract
Increasingly, the otolaryngologist is called on to provide exposure for the neurosurgeon performing transsphenoidal hypophysectomy. The 3 most common approaches for this exposure are the transnasal transseptal, sublabial transseptal, and external rhinoplasty approaches. We reviewed our series of 135 patients undergoing transnasal hypophysectomy for postoperative complications. In our series, we found that 18% of patients had a postoperative septal perforation, 2% of which were symptomatic; 6% of patients reported nasal cosmetic deformity; 13% reported transient lip numbness; and 3% reported postoperative nasal dysfunction. When comparing our complication rate with those published for the sublabial and external rhinoplasty approaches, we found the transnasal approach provides excellent exposure with less dissection and fewer postoperative complications. On the basis of these results, we believe that the transnasal transseptal approach provides excellent exposure for transsphenoidal hypophysectomy in all patients who require pituitary surgery.
