Purpose: The aim of this study was to investigate whether physical evaluations could be used for predicting the presence and severity of obstructive sleep apnea (OSA) in non-obese snoring patients. Methods: This is a retrospective study, and a total of 244 nonobese (body mass index, BMI, 2) snoring patients (178 men and 66 women; mean age=43.1±12.1 years) were included. Each patient underwent polysomnography and a thorough physical examination, including flexible nasopharyngoscopy and Müller maneuver. Patients were divided into four groups based on apnea-hypopnea index (AHI) scores: normal (simple snoring), AHI
