The aim of this study was to investigate the effects of nasal obstruction on sleep quality, in patients with nasal polyposis.
Material and methods: A group of patients (n=31) with obstructing nasal polyposis and 25 healthy cases as the control group were enrolled in the study. Patients with maxillofacial deformity, central sleep apnea, other primary sleep disorders, systemic diseases associated with sleep apnea, and overweight acording to National Health and Nutrition Examination Survey criteria were excluded from the study. Nasal obstruction was determined by nasal endoscopy and acoustic rhinometry. Sleep quality was evaluated, using visual analog scale, Epworth Sleepiness Scale and polysomnography.
Results: There was snoring in all patients in the study group and in 6 cases in the control group. There was a significant difference between the study and control groups by means of severity and the rate of snoring according to visual analog scalae (p<0,001). Daytime sleepiness scores, apnea-hypopnea index, and the longest apnea period were significantly higher in the patient group (p<0,001). There were 6 patients with apnea hypopnea index greater than 5 in the study group and no patients with apnea hypopnea index greater than 5 in the control group. However, duration of sleep periods, and rates of arterial oxygen saturation did not differ significantly between the patients and control groups. The cross sectional areas CSA2, CSA3, and total volume of both two nasal cavities were significantly lower in the patient group (p<0,05).
Conclusions: Findings of this study indicate that, nasal obstruction due to nasal polyposis impairs sleep quality by causing snoring and apnea-hypopnea, and increasing daytime sleepiness. However, further studies with more patients are needed to comment about obstructive sleep apnea patients with greater than 5 apnea hypopnea indexes.
