5. Conclusion
Objective gustatory dysfunction did not correlate with subjective gustatory symptoms. Age, sex (male), and objective olfactory dysfunctions were significant factors in objective gustatory dysfunction in patients complaining of chemosensory discomfort. Furthermore, the threshold subset score of the olfactory function test was significantly associated with objective gustatory dysfunction in older patients. We suggest that these characteristics must be understood, and clinicians should apply a gustatory function test in patients who are potential candidates for gustatory dysfunction regardless of subjective discomfort.
