Abstract
The aim of this study was to study the prevalence of obstructive sleep apnea syndrome in patients with nasal and nasopharyngeal pathologies. A total of 60 consenting patients between the age of 14 to 60 years with primary nasal and nasopharyngeal pathologies were taken up for the study. These patients underwent history taking, detailed clinical examination including BMI, diagnostic nasal endoscopy and overnight polysomnography. The polysomnography results of people with different pathologies were compared and analysed. Based on the analysis it was arrived that isolated pathologies like septal deviation, nasal polypi and adenoid hypertrophy provided a statistically significant association with occurrence and severity of OSA. Also, that patients with combined pathologies were more proportionately affected by OSA than those with isolated pathologies. Nasal and nasopharyngeal pathologies have significant association with obstructive sleep apnea syndrome and all patients with these pathologies need to undergo polysomnography along with other routine investigations.
