Middle Turbinate Resection: Issues and Controversies

Abstract

Diversity of opinion continues to exist among otolaryngologists regarding the potential benefits of preservation or resection of the middle turbinate during endoscopic ethmoidectomy. Rhinologists in favor of middle turbinate preservation cite the potential loss of olfactory function as well as diminished humidification and filtration of inspired air following its resection. In addition, the middle turbinate remnant could lateralize, causing frontal recess obstruction and frontal sinusitis. In general, it is accepted that a diseased or flail middle turbinate should be resected during ethmoidectomy to create a marsupialized surgical bed. However, in the case of a structurally sound middle turbinate, indications for resection vary significantly. We are reporting on 100 primary endoscopic ethmoidectomies for chronic rhinosinusitis followed for at least 2 years. Of these 100 sides, 50 included conservative partial middle turbinectomy and 50 were performed with middle turbinate preservation. The postoperative clinical and endoscopic findings revealed no difference in the incidence of frontal sinusitis or frontal recess stenosis between groups. We compared additional data and present our technique of conservative middle turbinate resection, which preserves a portion of this structure as an important anatomic landmark.
