title: Statistical analysis using the OMENS classification in Oriental patients with hemifacial microsomia: a comparative analysis with Western centers.
abstract: The purpose of this study was to analyze the statistical association between variable clinical phenotypes of the orbit, mandible, ear, nerve, soft tissue (OMENS) classification system in Oriental patients with hemifacial microsomia (HFM) and compare the data of Oriental children with data from other Western centers. One hundred consecutive patients with HFM referred to the Seoul National University Children Hospital were chosen between March 2009 and April 2010. They were classified according to the OMENS classification system, and statistical analyses were performed. The total OMENS scores were correlated significantly with all 5 component scores. In comparison with the previous data of Western centers, the orbit and ear components had statistically higher severity. Our retrospective study in Oriental children demonstrated that the pathophysiology of HFM is a complex process and that the components of HFM have a close relationship. For the ethnic difference, further etiologic studies on the molecular basis are required.
