摘要
目的：探讨Ｍｉｌａｒｄ法修复唇裂对上颌骨生长发育的影响。方法：本研究将３０只（３０天龄）日本纯种幼兔随机分成正常对照组（１０只）、人工造裂组（１０只）和Ｍｉｌａｒｄ法修补裂组（１０只）。术后２０周（３０周龄）处死全部动物并行头颅测量。结果：Ｍｉｌａｒｄ法修复唇裂后上颌骨的前后向较造裂组及正常对照组生长发育受限，同时上颌高度、后牙弓宽度及面后份宽呈代偿性增长，鼻中隔向裂隙侧偏曲。结论：Ｍｉｌａｒｄ法修复唇裂有抑制上颌骨生长的作用。
Objective:To study the effects of the cheiloplasty(Millard rotation advancement lip repair) on the maxillary growth.Me thods: Thirty Japanese white rabbits were randomly divided into three groups, Group I (unoperated control group), Group Ⅱ (unrepaired control group) and Group Ⅲ (repaired with Millard lip repair). All the animals were sacrified and measured on the clean slulls directly at 26 weeks postoperatively (30 weeks old).Results: It was found that Group Ⅲ (Millard repair group) had the anterioposterior growth disturbance of maxilla than Group I and Group Ⅱ, while the height of maxilla and width of posterior dental arch were larger than that of the two control groups for compensation, and the nasal septum of Group Ⅲ deviated to the cleft side.Conclusion: Millard rotation advancement lip repair operation has inhibitory effects on maxillary growth.
