完全性唇腭裂两种治疗模式的初步探讨

目的 探讨两种治疗模式对上颌牙槽骨的生长发育及腭咽闭合的影响。方法 将124例腭裂分为A组（63例），用Latham或Millard法，B组（61例）用早期软腭粘接法，测量124例唇腭裂上颌石膏模型，测量X线片牙槽裂区骨桥。结果 A组牙弓横径较B组大；A组在双侧唇腭裂，上牙弓的前后径小于B组，但随患者年龄增长，两组差别逐渐减小；A组在唇腭裂单侧和双侧牙槽裂区分别有63.0%和83.3%的骨桥生长；A组和B组分别有15.9%和35.2%的患者需要咽瓣手术。结论 A组稳定的上牙弓能对抗唇肌的压迫。维持牙弓的宽度，但A组9岁以后双侧唇腭裂牙弓的前后径还需进一步的追踪。A组需要咽瓣手术的病例较B组少。

A preliminary study of the two models treated by presurgieal orthopedics compared with early soft palate adhesion method

Objective To compare results of the growth and development of the upper dental arch and the velopharyngeal closure of the cleft patients treated by two methods Methods The dental cast of patient and X ray films were measured and the statistical medical records were analyzed Results The transverse distance of upper dental arch was found to be wider in group A than in group B The anterior posterior distance of the dental arch in bilateral cleft group was shorter in group A than in group B The difference of the two groups were gradually lessened as age increases Bony bridge in alveolar gap was 63% and 83 3% in unilateral and bilateral cleft group respectively 15% of cases in group A and 35 2% in group B needed pharyngeal flap Conclusions The stable upper dental arch in group A can opposes the pressure from the lip muscles, this maintains the width of the arch But A-P distance of upper dental arch in BCLP in group A should be followed up after the age of 9 years Pharyngeal flap is needed less in group A than in group B
