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.
