The evaluation of pattern and quality of sleep in patients with chronic rhinosinusitis with nasal polyps

Abstract

Objective: The goal of this study is to evaluate the impact of chronic rhinosinusitis with nasal polyps (CRSwNP) on sleep pattern and sleep quality before and after functional endoscopic sinus surgery using subjective and objective parameters.

Methods: Twenty-two patients with CRSwNP were evaluated. All subjects underwent assessment by nasal endoscopy, rhinomanometry and computed tomography. Sleep pattern and sleep quality were evaluated by Pittsburgh sleep quality index (PSQI) and polysomnography (PSG). All patients were reassessed 6 months after surgery.

Results: Nasal resistance decreased after the surgery (p<0.001). Postoperative PSQI scores were significantly lower than preoperative scores (p<0.001). The preoperative mean values of total apnea index and apnea-hypopnea index were 25.4 and 13.3, respectively. After surgery, the total apnea and apnea-hypopnea index had decreased significantly to 7.8 and 11.2, respectively (p=0.009 and 0.019, respectively).

Conclusion: In patients with CRSwNP, functional endoscopic sinus surgery significantly ameliorates sleep pattern and sleep quality. CRSwNP may be a predisposing factor for sleep related respiratory disorders.
