ABSTRACT
Objective:
To investigate the distraction osteogenesis technique in correction of severe retro-maxillary deformity following the repair of cleft palate.Methods:
10 patients were included in the study. Orthodontic treatment was used as a regular procedure before operation. Distraction osteogenesis technique was used to correct the deformity and malocclusion. 4 of patients applied with the external distractor and others with internal distractor. Latency period was 7 days. Distraction rhythm is 0.8~1 mm/d,2~4 times/d. Consolidation period was 8~12 weeks. Orthognathic surgery was done after distraction finished when necessary.Results:
The treatment process was smooth and no severe complication occurred. The maximum of distraction distance is 22 mm, and the minimum of distraction distance was 15 mm. No malunion or ununion occurred in all 10 patients. All the patients were satisfied with the results.Conclusion:
Distraction osteogenesis is more suitable for correction of severe retro-maxillary deformity following the repair of cleft palate. Bone transplantation is unnecessary during the operation process with easier handling and lower risk.
