Abstract

Cephalometric data of 28 Urban Indian Obese (Group I) and 15 urban Indian non obese (Group II) Polysomnography (PSG) diagnosed Obstructive sleep apnea (OSA) adult cases based on linear and angular measurements were compiled and compared with 20 age-sex matched controls (Group III).Co –relation of cephalometric variables with apnea Hypopnea index (AHI) was also evaluated and suitable statistical tests applied. In Group I, Cephalometric measurements; PAS (posterior airway space), PNS-P (Length of soft palate), MPH (Hyoid distance) were found to be highly significant (p<0.01) and G (Width of soft palate) was found to be significant (p<0.05). In Group II, Cephalometric measurements; PAS, PNS-P and G were found to be highly significant (p<0.01)), while SNB (relationship of mandible to cranial base), MPH, were found to be statistically significant (p<0.05). Positive correlation (p< 0.05, r2 = 0.163) was observed between MPH and AHI. No significant correlation was observed in other cephalometric variables with AHI in Group I and Group II. We concluded that predictable cephalometric measurements in OSA patients combined with PSG findings can be employed effectively for diagnosis and treatment planning in our settings.
