应用上颌前牵引治疗唇腭裂患者术后上颌发育不足的回顾分析

摘要

唇腭裂畸形是人类最常见的先天发育性缺陷之一.目前,唇腭裂手术是治疗畸形的主要手段,但术后患者常出现上颌发育不足,通常表现为面中部发育不足、凹陷,前牙反,严重影响了患者的面容美观和心理健康.上颌前牵引是通过牵引装置作用于上颌牙齿来刺激上颌骨周围4 个骨缝的改建,进而促进上颌骨向前移位,抑制下颌骨向前生长,改善凹陷的面型.本文就前方牵引治疗唇腭裂患者术后前牙反的报道作一综述.%Cleft lip and palate is one of the most common congenital craniofacial defects. At present, the optimal approach to treat it is operation. Maxillary retrusion which could be seen in cleft lip and palate patients after palate repair is characterized by the presence of concave profile, anterior crossbite and even psychological problems. Maxillary protraction can cause maxilla to move forward, inhibit mandible to move forward and improve the concave profile by stimulating 4 sutures in maxilla through a facemask. This article is to provide an overview of maxillary protraction in cleft lip and palate patients.
