Long‐term olfaction outcomes in transnasal endoscopic skull‐base surgery: a prospective cohort study comparing electrocautery and cold knife upper septal limb incision techniques

Abstract

Olfactory nerve fibers are at risk of injury during transnasal endoscopic skull‐base approaches. Olfactory outcomes for various techniques have not been thoroughly investigated. This study aims to report long‐term olfactory outcomes when a cold knife upper septal limb incision technique is used compared to monopolar cautery.
