Here, we examined the craniofacial characteristicsand body mass index of patients with obstructive sleep apnea-hypopnea syndrome and healthy counterparts,and investigated the relationship between these factors and onset of obstructive sleep apnea-hypopneasyndrome.MATERIAL AND METHODS:Sixty non-edentulous male with obstructive sleep apnea-hypopnea syndromediagnosed by conventional polysomnography were divided into two groups according to their bodymass index, which was used as an index of obesity( <25 kg/m2:non-obese, ≥ 25 kg/m2:obese). Craniofacialcharacteristics were analysed by cephalogram using Ricketts' method and the Downs-Northwesternmethod.RESULTS:The mean body mass index was greater in patients with obstructive sleep apnea-hypopneasyndrome compared with their healthy counterparts. As for the craniofacial characteristics of patients withobstructive sleep apnea-hypopnea syndrome, the mandible was relatively small and located posteriorly, andthe hyoid bone was at a lower position. However, in patients with obstructive sleep apnea-hypopnea syndrome,there was no significant difference in any of the cephalometric measurements between non-obeseand obese patients.CONCLUSION:Obesity and craniofacial skeletal abnormalities are non-reciprocal, independent causalfactors for obstructive sleep apnea-hypopnea syndrome., Original}, pages = {13--19}, title = {Obesity and Craniofacial Abnormalities are Independent Causal Factors for Obstructive Sleep Apnea-Hypopnea Syndrome}, volume = {41}, year = {2014} }
