Difference in Midface Rejuvenation Strategy Between East Asians and Caucasians Based on Analysis of Age-related Changes in the Orbit and Midcheek Using Computed Tomography

The differences between Caucasian and East Asian faces could lead to different age-related bony changes. We analyzed computed tomography (CT) scan images of East Asians to find objective differences in midface rejuvenation strategy between East Asians and Caucasians. We reviewed 54 East Asian individuals’ charts and facial CT images ranging in age-group: Group A (21–30 years), Group B (41–50 years), and Group C (61–70 years). No patients had congenital or acquired facial deformity and history of facial trauma. The anteroposterior length of the orbital roof and floor (LOR, LOF) and the angle of the anterior wall of the maxilla were recorded on parasagittal images through the midline of the orbit. The LORs at their midpoints showed significant differences between Groups A and B (p
