Abstract

To compare the cross-ethnic difference in dentofacial deformity profile and the associated surgical management in Chinese and Caucasian patients who required orthognathic surgery in Hong Kong and Glasgow, respectively. Material and Methods: This is a retrospective study of consecutive hospital patients' records from the Prince Philip Dental Hospital in Hong Kong and the Glasgow Dental Hospital and School in Glasgow from 2003 - 2012. Data pertaining to patient demographics, diagnosis, surgical treatment received and complications were recorded. Results: 581 and 217 cases were retrieved in Hong Kong and Glasgow, respectively. Both centres shared a similar patient demographic profile. Class III skeletal pattern was the most prevalent for both centres. A significantly higher prevalence for bimaxillary dentoalveolar hyperplasia, total vertical maxillary excess and mandibular asymmetry was seen in Hong Kong, while a higher prevalence for bimaxillary retrusion and zygomatic hypoplasia was found in Glasgow. To address these, segmental Le Fort I osteotomies, vertical subsigmoid osteotomies, and lower anterior subapical osteotomies were preferred in Hong Kong, while non-segmentalized Le Fort I osteotomies and sagittal split osteotomies were more preferred in Glasgow. Further facial aesthetics surgeries were performed, with septo-rhinoplasty common in Hong Kong and zygomatic augmentation common in Glasgow. Both centres shared a similar complication profile.
