폐쇄성 수면 무호흡 증후군 환자의 구개인두 수술 후 미각의 변화 = Changes of Taste Function after Palatopharyngeal Surgery in Obstructive Sleep Apnea Syndrome

다국어 초록 (Multilingual Abstract)

Background and Objectives Postoperative taste changes after uvulopalatopharyngoplasty
(UPPP) is regarded as an unusual and minor complication. This study aims to evaluate the objective
changes of taste threshold according to time course and subjective symptoms change.
Materials and Method With 45 patients who underwent UPPP and 35 patients who underwent
nasal surgery as control group, we have prospectively studied postoperative taste changes using
a questionnaire, and an electrogustometer (EGM) with regard to symptoms at 7th, 28th days after
the surgery. EGM was measured at 5 areas. Also, we have checked pre-operatively about the
serum level of zinc.
Results With EGM, the threshold of taste was increased at 7th days after the surgery (p<0.05),
but recovered 28th days after the surgery at the posterior part of the tongue in the UPPP group.
There were no significant changes in subjective taste dysfunction, smell dysfunction, tongue
sensory abnormality, and dysgeusia.
Conclusion Taste changes after UPPP was transient and they disappeared within the 1st postoperative
month. There were no patients who complained of subjective taste dysfunction, dysgeusia,
tongue sensory abnormality after UPPP.
