Hypogeusia as a complication of uvulopalatopharyngoplasty and use of taste strips as a practical tool for quantifying hypogeusia

Abstract

Hypogeusia is an uncommon complication of uvulopalatopharyngoplasty (UPPP) and few reports in the literature have documented it. Excision of part of the soft palate and damage to the glossopharyngeal nerve or its lingual branch as a result of diathermy or surgery are the possible causes. The case of a 45-year-old male who suffered hypogeusia following UPPP is reported herein. He reported no improvement over a 6-month period. Quantitative assessment of his taste threshold for the 4 basic tastes using taste strips showed a score of 7/18, indicating hypogeusia. The possibility of taste disorder as a postoperative complication should be discussed before patients consent to UPPP Postoperative taste threshold assessment should be done using taste strips if the patient complains of taste disorders.
