Title: The prevention and treatment of secondary dento-maxillofacial deformities with orthodontics and orthognathic surgery following the repair of cleft lip and palate
Abstract: Objective To prevent and treat secondary dento -maxillofacial deformities via the joint orthodontics and orthognathic surgery following the repair cleft lip and palate and to evaluate their outcomes. Methods 56 cases with secondary dento-maxillofacial deformities following the repair cleft lip and palate were prevented and corrected by the joint orthodontics and orthognathic surgery in our hospital. There were 30 males and 26 females, ranging from 8 to 38 years in age. 25 teenage cases were performed maxillofacial growth by orthodontics and alveolar bone graft. 31 adult cases were undergone preoperative orthodontics, their surgical procedures included: ① alveolar bone graft before orthoganathic procedure; ② Le Fort Ⅰ osteotomy; ③ multisegment Le Fort Ⅰ osteotomy; ④Le Fort Ⅰ osteotomy and bilateral sagittal split ramus osteotomy (BSSRO); ⑤BSSRO and genioplasty. Rigid internal fixation with Titanium palates and screws was applied and elastic traction of 2~3 weeks intermaxillary was essential in each case. All patients were undergone postoperative orthodontics and followed -up and ranged from 12 to 49 months. Results The teenage patients had a much-improved facial profile and occlusion. The adult cases had a satisfactory facial proportion with a good occlusion relationship and facial figure. Conclusion The joint orthodontics and orthognathic surgery could be performed satisfactorily to prevent and correct secondary dento-maxillofacial deformities following the repair cleft lip and palate. The authors recommend the joint orthodontics and orthognathic surgery should have individuation basing on patients' occlusion relationship and their requirements.
