Patients with odontogenic maxillary sinusitis (OMS) often complain of reduced taste sensitivity as well as nasal obstruction. The filter paper disc method (the conventional gustatory test) was applied to nine patients who underwent sinus surgery to open the inferior nasal meatus and sinus drainage, on three different days: 1day prior to surgery, 7days postoperative, and 28days postoperative. The same test was applied to nine non-clinical participants with or without clipping the nose to interfere with smooth nasal airflow on two different days. Acquired recognition thresholds for the four basic tastes of sweet, salty, sour, and bitter were assessed. In OMS patients, the recognition thresholds for all four tastes were markedly decreased at 7 and 28days postoperative, and subjective taste sensitivity and the elimination of nasal obstruction was improved. The mean recognition threshold for the four tastes correlated negatively with taste satisfaction scores. Clipping the nose in non-clinical participants induced increases in gustatory detection and recognition thresholds. Despite the small sample size and different ages and sexes of the study subjects, it was demonstrated that nasal obstruction in OMS patients and nose clipping in non-clinical subjects reduce taste reactivity, and surgical intervention to promote nasal airflow recovers impaired taste reactivity.
