Orthognathic surgery for the Asian patient and the influence of the surgeon's background on treatment

Abstract The aim of this study was to determine whether there are differences in esthetic preferences and orthognathic treatment for Asian patients between US- and Asian-trained surgeons. Twenty-five Caucasian-American, 23 Asian-American, 24 Asian oral and maxillofacial surgeons (OMFS) completed an Institutional Review Board (IRB)-approved survey. They were asked to rate seven Asian male and female profiles from most attractive to least attractive and to choose maxillary advancement, mandibular setback, or no treatment for an Asian male and female patient with a maxillomandibular discrepancy. There was no statistical difference for the most and least attractive rankings among the OMFS. Variations in ranking for intermediate profiles showed a statistical difference between the Asian- and US-trained OMFS. These intermediate profile rankings appeared to explain the differences in surgical treatment. Treatment recommendations for the Asian male among the OMFS, regardless of ethnicity, preferred maxillary advancement. For the Asian female, all Asian-trained OMFS preferred mandibular setback, while nearly 40% of US-trained OMFS preferred maxillary advancement ( p = 0.003). Differences in surgical management of the Asian patient were dependent on whether the surgeon trained in the US or in Asia and the gender of the patient. There was concordance between the Asian-American and Caucasian-American surgeons.
