【摘要】 目的探讨单侧完全性唇腭裂患儿术前正畸及手术前后的上腭裂隙变化。方法对18例单侧完全性唇腭裂患儿先用上颌腭托矫治器(PNAM)术前正畸治疗后,再进行唇裂修补手术。采用模型测量方法,比较患儿初诊时、手术前1个月和手术后2个月时的上腭裂隙变化。结果治疗后患儿唇部外形明显改善,腭部裂隙减小,患侧塌陷的鼻翼穹隆高度恢复。结论对单侧完全性唇腭裂患儿实施PNAM矫治,可明显改善唇形态及鼻畸形程度,减小牙槽突裂隙,并有效减小上唇张力。更多还原

【Abstract】 Objective To study the changes of palate cleft gap of complete unilateral cleft lip and palate(UCLP) infants before and after presurgical orthodontic and cheiloplasty.Methods The sample consisted of 18 complete UCLP infants who were treated using presurgical nasoalveolar molding(PNAM) appliance and cheiloplasty.The maxillary models were obtained at the initial visit,after PNAM treatment 1 month before cheiloplasty,and 2 months after cheilop-lasty.The change of palate cleft gap were compared.Results After PNAM treatment and cheiloplasty,the lip profile was obviously improved,cleft gap was reduced,and the height of ala nasi fornix was recovered.Conclusion PNAM treatment can improve the lip shape and nasal deformity degree of UCLP patient.The cleft gap and upper lip tension are reduced.更多还原
