Objective: Nasal obstruction is considered to be one of the risk factors for obstructive sleep apnea, together with a high arched narrow palate, elongated uvula, malocclusion, and tongue and tonsil size. The impact of nasal obstruction on sleep apnea is controversial, however, and its relation to sleep quality is rarely discussed. The purpose of this study was to investigate the independent effect of nasal obstruction on sleep quality.

Methods: Sixty-nine patients with nasal obstructive symptoms and without sleep apnea episodes were enrolled from September 2018 to August 2019, and compared before and after surgery with thirty-four patients who had benign diseases of the thyroid or parathyroid as a control group, to investigate effects of surgery. Sleep quality was evaluated using the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). All cases were reassessed at three months after surgery.

Results: The postoperative PSQI scores in the nasal surgery group were significantly lower than the preoperative scores (p < 0.001). In contrast, there was no statistically significance difference between the pre- and postoperative PSQI scores in the neck surgery group. Difference of PSQI scores before and after surgery in the nasal surgery group was significantly higher than the neck surgery group.

Conclusions: This double-arm study suggests that reduction of nasal disfunction with nasal surgery contributes significantly to sleep quality, in patients who may not have noticed their impaired quality of sleep previously because of their long-term nasal symptoms.
