Prospective characterization of postoperative nasal deformities in patients undergoing endoscopic endonasal skull-base surgery.

External nasal deformities following EES are more frequent than previously acknowledged. Postoperative deformities appear to be associated with NSF reconstruction and may be associated with surgery for nonpituitary neoplasms. Patients should be counseled on this potential outcome, and future studies should investigate how to minimize postoperative sequela.
