背景:术前鼻肺泡成型(NAM)是唇腭裂最常见的术前治疗方法。然而,NAM可能有一些限制,例如需要很高的技术敏感性和频繁的访问。为了简化设备,一些学者将传统的NAM改为由肺泡成型板和鼻钩组成的分体式NAM。本研究使用三维(3D)测量比较了分裂NAM和传统NAM对鼻唇沟软组织的塑形效果。
方法:选择单侧唇腭裂患者39例,分为2组。13例患者用split-NAM治疗,而其他26例患者用传统NAM治疗。记录所有患者NAM治疗前后颅面软组织的3D图像,并通过三维软件进行测量。使用SPSS软件对两组测量值进行统计学分析。
结果:治疗后,分裂-NAM组鼻部软组织对称性在垂直方向和前后方向上的改善优于NAM组,但在横向上有所改善。两组唇侧软组织对称性差异无统计学意义。
结论:劈开式NAM可以更好地抬高裂侧的鼻翼和鼻孔,对鼻翼外缘有更好的正向作用,鼻基,和鼻孔。然而,传统的NAM能更好地减小鼻底的宽度。
BACKGROUND: Presurgical nasoalveolar molding (NAM) is the most common preoperative treatment for cleft lip and palate. However, NAM may have some limitations such as requiring high technical sensitivity and frequent visits. To simplify the device, some scholars have changed the traditional NAM into a split-NAM consisting of a alveolar molding plate and a nasal hook. This study compared the shaping effect of split NAM and traditional NAM on nasolabial soft tissue using three-dimensional (3D) measurement.
METHODS: A total of 39 patients with unilateral cleft lip and palate (UCLP) were enrolled and divided into 2 groups. 13 patients were treated with split-NAM while the other 26 patients were treated with traditional NAM. 3D images of all patients\' craniofacial soft tissue before and after NAM treatment were recorded and measured by three-dimensional software. Statistical analysis of measurements in both groups was performed using SPSS software.
RESULTS: After treatment, nasal soft tissue symmetry in the split-NAM group was better improved than that in the NAM group in vertical and anterior-posterior direction, but was worse improved in transverse direction. There was no significant difference in labial soft tissue symmetry between two groups.
CONCLUSIONS: The split NAM can better elevate the alar and nostrils of the cleft side, and have a better forward effect on alar outer edge, nasal base, and nostrils. However, the traditional NAM can better reduce the width of nasal base.
