To evaluate the curative effect of presurgical nasoalveolar molding (NAM) in the treatment of infants with bilateral complete cleft lip and palate (BCLP).
Nine infants with BCLP were included. Presurgical alveolar molding was used to bring the premaxilla back into proper alignment with the lateral segments in the maxilla arch. Presurgical nasal molding produced tissue expansion of the short columella and corrected the nasal tip cartilages. Up to 5 months of active treatment was needed before lip repair. Student's t test was used for data analysis with SPSS 15.0 software package.
After presurgical NAM in 9 infants with BCLP, the posterior lateral alveolar segments were aligned while retracting the premaxilla, the premaxilla had been returned from 37.64mm to 29.94mm within the maxillary arch (P<0.01). The nasal alar base width was significantly reduced following NAM(P<0.05). The columella was nonsurgically lengthened from 1.13mm to 3.78mm(P<0.05).
In order to obtain satisfactory lip-nose configuration for BCLP, presurgical NAM is useful in cleft lip and palate team approach.
评估术前鼻牙槽骨塑形（NAM）治疗双侧完全性唇腭裂（BCLP）患儿的疗效。
纳入9例BCLP患儿。术前采用牙槽骨塑形使前颌骨与上颌弓外侧段恢复正常对位。术前鼻塑形可使短鼻小柱组织扩张并矫正鼻尖软骨。唇修复术前需进行长达5个月的积极治疗。采用SPSS 15.0软件包进行数据分析，采用Student's t检验。
9例BCLP患儿术前进行NAM后，后外侧牙槽段对位，同时前颌骨回缩，前颌骨在上颌弓内从37.64mm回缩至29.94mm（P<0.01）。NAM后鼻翼基底宽度显著减小（P<0.05）。鼻小柱非手术延长，从1.13mm延长至3.78mm（P<0.05）。
为了使BCLP患儿获得满意的唇鼻形态，术前NAM在唇腭裂综合治疗中具有重要作用。
