Background: Obstructive sleep apnea is a global health problem characterized by collapse of upper airway during sleep. It is commonly associated with road traffic accidents, diabetes mellitus and cardiovascular disease. The study aimed to measure the different otorhinolaryngologic parameters of patients with obstructive sleep apnea and to compare these findings with different class of polysomnography.
Methods: A hospital based cross-sectional study was carried out among patient coming to department of Otorhinolaryngology of Kathmandu Medical College and Teaching Hospital. In total 74 patients with obstructive sleep apnea participated in this study. Sociodemographic details, co-morbid illness and anthropometric measurements were recorded. Data was presented in the form of mean, standard deviation and percentage. Chi-square, student’s t-test were done using Statistical Package for the Social Sciences version 16. A p-value of <0.05 was considered statistically significant.
Results: The mean age of the patient was 47.43±11.30 years. Majority of the patients were male. Out of 74 patients, 24 (32.4%) patients were obese, 22 (29.7%) were overweight. The PSG showed 49 (66.2%) participant had severe obstructive sleep apnea. According to Modified Mallampati score, 28 (37.8%) of patients belonged to Class 3, 20 (27%) belonged to Class 2. There was no significant association observed between the studied variables and polysomnographic results.
Conclusion: Male and old age were the predominant factor in obstructive sleep apnea patients. In patients with snoring, the Otorhinolaryngologists should rely on thorough medical history, anatomic examination, radiological examination of head and neck should be done.
