【摘要】：目的评价鼻牙槽嵴塑形(PNAM)矫治器对单侧完全性唇腭裂患者腭部畸形的矫治效果。方法研究对象分为3组,每组19例。A、B组均为非综合征单侧完全性唇腭裂患者,A组在唇腭裂手术前先行PNAM矫治,B组术前未行PNAM矫治。C组为3月龄左右鼻唇部及腭部发育正常婴儿。获取A组PNAM矫治前及PNAM矫治后唇裂术前、B组唇裂术前和C组的标准腭部模型正位照片,对模型照片进行测量。采用SPSS 21.0软件进行分析。结果 A组PNAM矫治后与矫治前相比,患者的牙弓宽度(AW)、牙弓周长(AC)、腭部面积(PA)明显增加(P0.05),腭部裂隙宽度(CPW)、牙槽突裂隙宽度(CWA)、牙槽突裂隙矢状向距离(CWAS)与水平向距离(CWAH)、前颌突倾斜度(PMD)、裂隙面积(CA)明显减小(P0.05);但与C组相比仍有差距(P0.05);B组AW、CPW、CA及PA较A组矫治前均明显增加(P0.05)。多元方差分析表明,3组上颌结节间距离(TW)均无统计学差异(P0.05)。结论 PNAM矫治是早期有效改善患者腭部原发畸形的非手术治疗手段之一。
[Abstract]:Objective to evaluate the effect of (PNAM) appliance for correction of unilateral complete cleft lip and palate. Methods the subjects were divided into 3 groups, 19 cases in each group. All patients in group A were treated with PNAM before cleft lip and palate surgery, all of them were non-syndromic patients with complete cleft lip and palate, and the patients in group A were treated with PNAM before cleft lip and palate surgery. Group B was not treated with PNAM before operation, and group C was 3 months old with normal nasolabial and palatal development. The normal cleft palate model of group A and group C were taken before and after PNAM and PNAM, and the normal cleft palate model was measured. The software SPSS 21 1.0 was used to analyze. Results in group A, after PNAM treatment, the width of dental arch, the width of (AC), the width of alveolar process and the width of alveolar process, (CWA), were significantly increased after PNAM treatment (P0.05), and the width of alveolar cleft process (CWA),) was significantly increased in group A (P0.05). Sagittal distance (CWAS) of alveolar fissure and horizontal distance (CWAH),) the area of (PMD), fissure area (CA) decreased significantly (P0.05). However, there was still a difference compared with group C (P0.05 AW,CPW,CA and PA in); B group were significantly higher than that in group A before treatment (P0.05). Multivariate analysis of variance showed that there was no significant difference in distance between maxillary nodules (TW) among the three groups (P0.05). Conclusion PNAM is one of the early and effective methods to improve the primary malformation of palate.
