Abstract
BACKGROUND/ PURPOSE: In this study we aimed to investigate the prevalence of abnormal nasality in patients with unilateral rhinosinusitis and their nasality outcomes following functional endoscopic sinus surgery (FESS). METHODS: A total of 42 patients with unilateral chronic rhinosinusitis who underwent unilateral FESS between April 2016 and November 2017 were enrolled. Questionnaires on sinonasal symptoms and nasality were recorded. The change in the nasalance score of vowels [a], [i] [u], nasal consonant [m], 2 nasal syllable repetitions, and 2 Chinese sentences were measured. The patients were evaluated preoperatively, 6 months, and 12 months after the operation. The patients were divided into two groups, wide opening surgery and limited surgery, according to the severity of the disease. RESULTS: Among 42 patients, the subjective reports showed that one-third of unilateral chronic rhinosinusitis (CRS) patients had abnormal nasality preoperatively and significant improvement following FESS. The Lund-Mackay score was significantly negatively correlated with preoperative nasalance of [i] and positively correlated with change of nasalance of [i]. The increase in the value of [i] is statistically significant (p = 0.01) following FESS. In the further subgroup analysis, the change in nasalance was significant in the wide opening surgery group, but not in the limited surgery group. CONCLUSION: Although only one side of the nasal airway was involved, one-third of the patients reported abnormal nasality. In patients with more disease severity who underwent wide opening surgery, the nasalance significantly increased 1 year after FESS. The increase in the objective nasalance score was corresponded to a significant improvement of subjective self-reported nasality assessment postoperatively.
