目的探讨鼻牙槽嵴塑形(PNAM)矫治器对单侧完全性唇腭裂腭部畸形的矫治效果。方法统计分析2012年5月至2014年5月洛阳市第一中医院收治的50例单侧完全性唇腭裂腭部畸形患儿的临床资料。结果观察组的鼻尖高度,鼻小柱高度与宽度,双侧鼻孔高度、宽度、周长与面积及上唇面积均明显大于对照组(P<0.05),双侧鼻翼高度差、鼻底裂隙宽度、鼻尖与鼻小柱倾斜度均明显小于对照组(P<0.05);但与正常组婴儿相比仍有差距(P<0.05);三组婴儿的内眦间距、鼻部宽度、口角间距及非裂隙侧鼻腔宽度之间比较差异均无统计学意义(P>0.05)。结论 PNAM矫治器对单侧完全性唇腭裂腭部畸形的矫治效果显著。
Objective To investigate the effect of nasal alveolar ridge shaping (PNAM) appliance on the correction of unilateral cleft palate deformity. Methods The clinical data of 50 children with palatal deformity of unilateral complete cleft lip and palate from May 2012 to May 2014 in Luoyang First Hospital were statistically analyzed. Results The height of nasal tip, the height and width of columella, the height, width, circumference, area and upper lip area of bilateral nostrils in observation group were significantly higher than those in control group (P <0.05) The inclination of the tip of the nose and the columella were significantly lower than those of the control group (P <0.05), but there was still a significant difference compared with that of the normal group (P <0.05). The internal foramina, nasal width, There was no significant difference in nasal width at cleft side (P> 0.05). Conclusion PNAM appliance is effective in treating unilateral complete cleft palate deformity.
