Abstract

Intro: Evaluation of gustatory dysfunction is important in patients with subjective chemosensory dysfunction, especially for geriatrics. This study investigated the clinical characteristics associated with objective gustatory dysfunction in patients with chemosensory dysfunction. Methods: The Medical records of patients who visited the smell and taste center in a tertiary medical center were reviewed. Patients who underwent all the psychophysical olfactory and chemical gustatory function tests and the subjective questionnaire about chemosensory function were enrolled in this study. The clinical characteristics associated with the objective diagnosis of gustatory dysfunction were statistically analyzed. Results: A total of 219 patients were enrolled; 180 were objectively diagnosed as having normal gustatory function, and 39 were objectively diagnosed as having gustatory dysfunction. Subjective recognition of gustatory function was not associated with objective gustatory function. Age, sex, objective olfactory function, and the threshold and discrimination scores for the olfactory function test were significant factors in the multivariate analysis. When the patients were further divided according to age, the threshold test scores rather than other subsets in the olfactory function test were significantly associated with objective gustatory dysfunction in patients 60 and older. Conclusion: In older adult male patients with olfactory dysfunction, gustatory function should be considered regardless of subjective gustatory dysfunction.
