Abstract
The aim of this retrospective study is to investigate the spectrum and management of dentofacial deformities in a multiethnic Asian community. Over a period of 3 years (2001 to 2003), 212 patients with dentofacial deformities who had undergone orthognathic surgery in a national tertiary specialist center in Singapore were reviewed. Patients with cleft lip and palate or syndromes were excluded. The mean age (range: 16 to 58 years) of the patients was 24.0 years (SD 6.4) and the ratio of female to male was 1.3:1. The predominant ethnic group was Chinese (91.5%). The majority of the patients had skeletal Class III pattern (68%). Asymmetry was diagnosed in 36% of all cases and in 48% of skeletal Class III cases. Vertical maxillary excess was diagnosed in 21% of all cases and in 47% of skeletal Class II cases. Bimaxillary surgery involving LeFort and bilateral sagittal split osteotomies was performed in 84% of skeletal Class III cases and in 73% of all cases. Segmental osteotomy and genioplasty were performed in 41% of the cases. The findings suggest that the majority of the patients were young Chinese adults with two-jaw deformities requiring bimaxillary surgeries with genioplasty or segmental osteotomy. This finding may reflect the greater severity of dentofacial deformities in patients in the Asian community.
