The comparison of cephalometric characteristics in nonobese obstructive sleep apnea subjects and primary snorers cephalometric measures in nonobese OSA and primary snorers

The objective of the study is to evaluate the cephalometric characteristics and investigate the measurement differences between habitual snorers and subjects with obstructive sleep apnea (OSA) in nonobese Turkish male population. The study design is prospective and nonrandomized. The setting is sleep-snoring center of referral hospital. Total of 60 male subjects constituted OSA ( n = 20), habitual snorer ( n = 20) and control group ( n = 20). Clinical evaluation, Epworth sleepiness scale scoring, flexible nasopharyngoscopy, polysomnography, Tweed and Delaire analysis on cephalometric images were performed. The main outcome meaasures include cranial base maxillary angle (SNA), cranial base mandibular angle (SNB), posterior airway space (PAS), mandibular plane and hyoid distance (MPH), soft palate length, soft palate thickness, cranial height ratio (C2/C1), cranial base angle (C1⊥C3), and craniofacial angle (C3⊥F1) parameters were compared. In comparison of OSA and habitual snorers, PAS at palatal and tongue base level ( p = 0.037, p = 0.001), MPH ( p = 0.07), C3⊥F1 ( p = 0.001) were found statistically different. In comparison of controls with OSA and habitual snorers PAS at palatal level ( p
