Impact of endoscopic sinus surgery on sleep quality in patients with chronic nasal obstruction due to nasal polyposis.J Craniofac Surg. 2009 Mar; 20(2):446-9.JC
The aim of this study was to investigate the effect of endoscopic sinus surgery on sleep quality in a patient group who has chronic nasal obstruction resulting from nasal polyposis.
Twenty-seven patients with nasal polyposis, filling at least 50% of each nasal passage, were enrolled in the study. Assessment of nasal patency was determined by nasal endoscopy and acoustic rhinometry. All patients underwent endoscopic sinus surgery with polypectomy. Sleep quality was evaluated, using visual analog scale, Epworth sleepiness scale, and polysomnography before and 3 months after the surgery.
Nasal resistance decreased significantly after the surgery (P < 0.01). Snoring scores were significantly improved postoperatively (P < 0.01) and completely disappeared in 9 of 27 patients. A significant improvement occurred in mean daytime sleepiness scores in the postoperative period (4.14) as compared with the preoperative values (9.44; P < 0.01). There was no significant difference between preoperative (6.85) and postoperative (5.53) mean values of apnea-hypopnea index (P = 0.55).
Endoscopic sinus surgery with polypectomy significantly improves sleep quality, including snoring and daytime sleepiness in patients with chronic nasal obstruction due to nasal polyposis. However, it has a limited benefit on apnea-hypopnea index scores.
