目的探讨口内入路牵引成骨术配合语音治疗对唇腭裂术后继发上颌骨发育不良患者的治疗效果。方法对2007—2009年在南昌大学口腔医院接受治疗的9～12岁唇腭裂术后继发上颌骨发育不良畸形患者21例采用高位LeFortI型截骨术,将上颌骨完全断离,安装口内牵引器,术后3个月开始语音训练,定期接受发音指导和语音测评,记录结果并进行统计分析。结果 21例患者手术效果满意,未见严重并发症,通过语音治疗,发音改善明显。结论骨牵引成骨术用于矫治唇腭裂术后继发上颌骨发育不良,可早期解除上颌骨畸形,在一定程度上改善患者的腭咽闭合功能,再配合语音治疗可有效提高语音效果。
Objective To investigate the therapeutic effect of intraoral approach distraction osteogenesis combined with phonotherapy on postoperative patients with maxillary dysplasia after cleft lip and palate. Methods Twenty-one patients with cleft lip and palate secondary to maxillary hypoplasia who underwent treatment at the Stomatological Hospital of Nanchang University from 2007 to 2009 were treated with high LeFortI osteotomy. The maxillary bone was severed completely and intraoral traction Devices, voice training began 3 months after surgery, regularly receive pronunciation guidance and voice evaluation, record the results and statistical analysis. Results 21 patients were satisfied with the operation results, no serious complications, pronunciation therapy, pronunciation improved significantly. Conclusion Bone traction osteogenesis is an effective method to correct maxillary dysplasia secondary to cleft lip and palate. It can relieve the maxillary deformity early and improve the velopharyngeal function to a certain degree. Combined with speech therapy, it can effectively improve speech effects.
