目的：观察术前应用鼻-牙槽突矫治器在单侧完全性唇腭裂患儿正畸治疗中的疗效。方法选取我院2011年1月至2013年1月间收治的40例单侧完全性唇腭裂患儿为观察对象，随机均分两组，观察组患儿接受术前应用鼻-牙槽突矫治器正畸治疗，对照组患儿不进行术前正畸治疗。比较两组患儿治疗前后上唇裂隙、上前牙槽突裂隙、鼻底宽度、鼻小柱长度以及鼻翼外观满意度等。结果两组患儿术前上唇裂隙宽度、上前牙槽突裂隙宽度、鼻底宽度、鼻小柱长度比较差异均无统计学意义(P>0.05)。观察组患儿治疗后上唇裂隙宽度、上前牙槽突裂隙宽度和鼻底宽度分别为(5.10±1.83) mm、(6.40±2.01) mm和(23.29±2.19) mm，均小于治疗前，鼻小柱长度为(3.89±1.10) mm，大于治疗前，其比较差异均有统计学意义(P<0.05)。观察组患儿治疗后上唇裂隙宽度、上前牙槽突裂隙宽度和鼻底宽度均小于对照组，鼻小柱长度大于对照组，其比较差异均有统计学意义(P<0.05)。对照组患儿治疗后上唇裂隙宽度和上前牙槽突裂隙宽度分别为(8.93±1.73) mm和(9.49±1.81) mm，均大于治疗前，其比较差异均有统计学意义(P<0.05)；对照组患儿治疗后鼻底宽度和鼻小柱宽度分别为(29.29±2.11) mm和(1.26±0.22) mm，均大于治疗前，其差异均无统计学意义(P<0.05)。观察组患儿家属对鼻翼外观的满意度为(8.94±1.10)分，大于对照组的(4.09±1.13)分，比较差异有统计学意义(P<0.05)。结论术前鼻-牙槽突矫治器治疗作为单侧完全性唇腭裂患儿手术治疗前重要的步骤，可明显减少患儿上唇裂隙宽度、上前牙槽突裂隙宽度，增加鼻小柱长度，减少鼻底宽度，提高手术治疗效果。

Objective To observe the effect of presurgical nasoalveolar molding (PNAM) in the treatment of children with unilateral cleft lip and palate. Methods From January 2011 to January 2013, 40 children with unilater-al cleft lip and palate were selected and randomly divided into two groups: the observation group and the control group. The observation group received presurgical nasoalveolar molding treatment preoperatively, and the control group did not received presurgical nasoalveolar molding treatment. The widths of cleft lip, the widths of dentoalveolar cleft, the widths of basis nasi, the length of the columella and the nose look satisfaction of the two groups before and after treatment were compared. Results Before operation, the widths of cleft lip, the widths of dentoalveolar cleft, the widths of basis nasi, the length of the columella between the two groups showed no statistically significant difference (P>0.05). After treatment, the widths of cleft lip, dentoalveolar cleft and basis nasi of the observation group were (5.10 ± 1.83) mm, (6.40 ± 2.01) mm and (23.29 ± 2.19) mm, respectively, which were less than those before treatment. The length of the columella of the observation group was (3.89±1.10) mm, which was significantly greater than before treatment (P<0.05). After treatment, the widths of cleft lip, dentoalveolar cleft and basis nasi of the observation group were significantly less than that of the control group, and the length of the columella of the observation group was sig-nificantly greater than that of the control group (P<0.05). The widths of cleft lip and dentoalveolar cleft of the control group after treatment were (8.93 ± 1.73) mm and (9.49 ± 1.81) mm, which were significantly greater than that before treatment (P<0.05). The widths of basis nasi and the length of the columella of the control group after treatment were (29.29±2.11) mm and (1.26±0.22) mm, which were significantly greater than that before treatment (P<0.05). The satis-faction degree of appearance of nose of the observation group was (8.94 ± 1.10), which was significantly greater than that of the control group (4.09±1.13) (P<0.05). Conclusion The preoperative presurgical nasoalveolar molding treat-ment, as an important step before surgery for children with unilateral cleft lip and palate, can obviously reduce the widths of cleft lip and dentoalveolar cleft, increase the length of the columella, reduce the width of the basis nasi, and improve the effect of surgical treatment.
