Title: Poster 159: The Maxillary Position and the Stability of Distraction Osteogenesis in the Adult Cleft Patient
Abstract: The purpose of this study was to evaluate the stability of the maxilla after advancement with distraction osteogenesis for treating adult cleft lip and palate patients. Seven cleft patients were referred from the Department of Orthodontics for surgical correction of their hypoplastic maxilla. Six patients were male and one was female. The average age of the patients was 21.6 ± 3.6 years old (range: 17 to 26). The follow-up period was more than 1 year. The cephalometric measurement of the maxillary position was analyzed. n/a The position of maxilla with advancement under 10 mm showed relatively stable results. On the contrary, the patients with advancement more than 10 mm showed severe relapse. Most of the maxilla was moved to the inferior direction and did not show an openbite tendency. Maxillary distraction osteogenesis showed stability in the patients with advancement under 10 mm. The vertical position of the maxilla is a bit difficult to control during the distraction osteogenesis.
