Surgical management of chemosensory disorders.

As additional understanding of the histopathologic basis of chemosensory dysfunction has been achieved, several actual and potential surgical approaches for correction have been devised. These currently include correction of steroid-dependent anosmia and hyposmia due to septal deviation. Posttraumatic anosmia might be correctable in the future. Surgical approaches to dysgeusia are sparse, probably due to a paucity of information on the causes of this disorder.
