Olfactory outcomes following endoscopic pituitary surgery with or without septal flap reconstruction: a randomized controlled trial

Abstract

Endoscopic pituitary surgery results in decreased olfaction with or without deploying a septal flap. However, use of the HB flap for reconstruction can worsen hyposmia at least 6 months after surgery. Olfaction should be considered when use of the HB flap is planned.
