完全性唇腭裂婴儿术前正畸治疗的临床研究

Clinical research of presurgical orthodontic treatment of complete cleft lip and palate infant

目的观察术前鼻-牙槽突矫治器(PNAM)在完全性唇腭裂婴儿术前矫治中的作用。方法采用术前鼻-牙槽突矫治器对45例非综合征性完全性唇腭裂患儿(平均年龄为18.33 d)进行唇裂术前正畸治疗,测量治疗前后的鼻小柱倾斜度、鼻小柱长度、鼻孔宽度、鼻孔高度和牙槽骨裂隙宽度,并用SPSS 10.0软件进行统计分析。结果经PNAM术前正畸治疗后,鼻小柱倾斜度、鼻小柱长度、鼻孔宽度、牙槽突裂隙均明显减小,鼻孔高度明显增加,除双侧完全性唇腭裂患儿较小侧的鼻孔宽度外其余项目治疗前后的差异均有统计学意义(P<0.05)。结论 PNAM能明显改善完全性唇腭裂患儿的鼻部形态,减少牙槽骨裂隙宽度,从而减少手术难度,提高整复效果。

Objective To observe the effective of presurgical nasoalveolar molding（PNAM） therapy in the treatment of complete cleft lip and palate infant.Methods PNAM was performed as presurgical orthodontic treatment in 45 in-fants（aged 18.33 d） with nonsyndromic complete cleft lip and palate.The columella deviation,columella length,nostril width,nostril height and width of alveolar cleft were measured before and after treatment.The data were analyzed by SPSS 10.0.Results After PNAM treatment,the columella deviation,columella length,nostril width and width of alveolar cleft obviously decreased,while the nostril height increased.Except for smaller cleft nostril width of bilateral complete cleft lip and palate infant,other measurement items had statistics difference（P0.05）.Conclusion PNAM can improve nasal profile of complete cleft lip and palate infant and decrease the width of alveolar cleft,and make it easy for the operation of cleft lip and palate.
