Abstract
OBJECTIVE: This study investigated the relationship between disease severity and taste and smell functions in patients with obstructive sleep apnoea syndrome.
METHODS: A total of 65 patients with recurrent upper airway obstruction during sleep were included. Participants were divided into four groups according to apnoea-hypopnoea index, obtained on polysomnography. Smell and taste tests were performed on these patients.
RESULTS: A significant difference was observed between the smell thresholds of the groups for the identification test (p = 0.016). In the taste test, significant differences were observed between the groups in terms of sweet, sour, salty and bitter taste test thresholds (p = 0.029, p = 0.0005, p = 0.001 and p = 0.017, respectively).
CONCLUSION: As sleep apnoea severity increased (according to the apnoea-hypopnoea index) in obstructive sleep apnoea syndrome patients, the taste and smell thresholds decreased due to the effect of neuropathy and inflammation in the upper respiratory tract.
