Electrogustometry: validation of bipolar electrode stimulation.

Electrogustometry (EGM) is a practical way to test taste. It is typically performed using unipolar electrodes, with the anode on the tongue and the cathode on the hand, forearm, or neck. This results in electric current passing through nontaste tissues and adds a level of impracticality to its clinical application.

Postoperative olfaction in chronic sinusitis: smokers versus nonsmokers.

In order to study the efficacy of surgical intervention, as well as the influence of cigarette smoking on olfaction in clinical states, we examined olfactory ability by means of the University of Pennsylvania Smell Identification Test (UPSIT). We enrolled 37 patients 21 to 60 years of age who underwent surgery for chronic sinusitis. Normosmia was defined as an UPSIT score of 30 or more.
