Intercenter comparison studies for patients with unilateral cleft lip and palate in Japan

目的：探讨单侧唇腭裂的有效治疗方法。对象与方法：1992 ~ 1994年在新泻大学、东北大学、东京大学、昭和大学、爱知学院大学、大阪大学6所唇腭裂中心治疗的单侧唇腭裂95例。我们检查了5个因素(1.协议；侧位脑电图，3个。研究models.4。嘴唇和鼻子的形状，5。结果：6个中心的治疗方案完全不同，每个中心都采用自己的治疗体系进行治疗。此外，我们发现了一些操作系统和案例的趋势，分析可以从多个方面审视各种影响因素。然而，当我们考虑文献收集时的偏差时，似乎有必要对正畸治疗的存在、冷冻成形术的时间、腭成形术的时间和开始正畸治疗的时间的相关性进行解释，病例数量的不均匀性。

Objective : The aim of this study is to establish the effective and treatment of unilateral cleft lip and palate.Subjects and Methods : 95 unilateral cleft lip and palate cases bone in 1992-1994, and treated at 6 cleft lip and palate centers (Niigata University, Tohoku University, Tokyo University, Showa University, Aichi-Gakuin University and Osaka University.) We examined 5 factors (1.protocol,2.lateral cephalograms, 3.Study models.4.Lip and Nose form,5.Speech therapy)Results : Six centers were different about treatment protocol entirely, and each centers treated it with an original treatment system. In addition, we found some tendency about operation system and cases, and analysis was able to examine various influence factors from many aspects. However, when we considered bias at the time of document collection, it seemed that it was necessary to perform interpretation about relevance with presence of orthognatic treatment, time of chiloplasty, palatoplasty, and timing of starting orthodontic treatment, unevenness off the number of the cases.
