摘要
目的:通过比较分析术前经鼻牙槽塑形矫治器(Presurgical nasoalveolar molding,PNAM)技术治疗以及未经PNAM治疗的单侧完全性唇裂患儿术后颜面部对称性以及牙弓发育情况,探讨术前PNAM的远期影响。方法:共收集21例在安徽省儿童医院治疗的单侧完全性唇裂患儿,PNAM组8例,非PNAM组13例。对患儿进行取模和摄影测量,分别评估PNAM治疗对单侧完全性唇裂患儿牙弓形态以及鼻唇对称性的影响。结果:相较于非裂隙侧,PNAM组裂隙侧尖牙区的宽度明显缩窄(P<0.05),非PNAM组裂隙侧各区牙弓明显缩窄,但PNAM组与非PNAM组之间各区牙弓比较,差异无统计学意义(P>0.05)。与非PNAM组相比,PNAM组患儿的鼻底对称指数更佳(P<0.05),其余指数的差异无统计学意义(P>0.05)。结论:从长远来看,与非PNAM组相比,PNAM组对牙弓形态的发育影响以及鼻唇对称性无统计学差异。医师在早期选择PNAM治疗时可以不必拘于PNAM对牙弓形态的负面影响,但若想长期维持鼻部形态和唇部的对称性,仅靠术前PNAM治疗是不够的。
Objective To investigate the long-term effects of presurgical nasoalveolar molding(PNAM)by comparing and analyzing the postoperative facial symmetry and dental arch development in children with unilateral complete cleft lip treated with and without PNAM before surgery.Methods A total of 21 children with unilateral complete cleft lip treated in Anhui Children's Hospital were collected,8 in the PNAM group and 13 in the non-PNAM group.The children were modeled and took photos to assess the effects of PNAM treatment on dental arch morphology as well as nasolabial symmetry in children with unilateral complete cleft lip.Results Compared with the non-cleft side,canine to midline transverse width on the cleft side was significantly narrowed in the PNAM group(P<0.05),and the arch of each region on the cleft side was significantly narrowed in the non-PNAM group,but there was no significant difference in the arch of each region between the PNAM group and the non-PNAM group(P>0.05).Compared with the non-PNAM group,the children in the PNAM group had better nasal floor symmetry index(P<0.05),and the differences in the remaining indices were not statistically significant(P>0.05).Conclusion From a long-term perspective,compared to the non-PNAM group,there was no statistical difference in dental arch morphology and nasolabial symmetry in the PNAM treatment group.Doctors may not be bound to the negative effects of PNAM on dental arch morphology when choosing PNAM treatment in the early stages,and preoperative PNAM treatment alone is not sufficient if nasal morphology and lip symmetry are maintained in the long term.
