Olfication - a clinical approach.

Olfactory dysfunction usually occurs secondary to ENT causes, and most patients with olfactory problems prefer to consult an otolaryngologist. 1a some cases the ENT surgeon is required to inculcate a systematic approach while dealing with such patients in order to screen the possibility of other causes (apart from ENT). He may in turn either collaborate with another specialist (neurologist, ophthalmologist, neurosurgeon) for proper diagnostic work- up or otherwise counsel the patient in case of a benign prognosis. Thus a basic knowledge about the applied pathophysiology of olfaction for its proper clinical approach is a must for every practicing ENT surgeon. We present the gist of the experience with olfaction at the Smell and Taste Center of the University of Pennsylvania USA that is relevant to the practicing otolaryngotogist. We present the information in two complementary parts: a clinical approach and its quantification and management which will be published in a subsequent issue of this journal.
