头颅定位测量对大年龄未手术腭裂患者上颌骨发育的研究分析

Cephalometric analysis of maxillary development in adult unoperated cleft palate patients.

目的研究分析大年龄未手术腭裂患者上颌骨发育的情况。方法运用电脑图象测试系统，对３７名未手术的大年龄腭裂患者头颅定位Ｘ片进行测量分析，并与２０名正常成人对照。结果大年龄未手术患者上颌骨前后发育受限，而垂直向发育与正常成人无显著性差异。

Objcctive Analysis of maxillary development in adult unoperated cleft palate patients. Methods Lateral cephalometric radiographs of 37 case of adult unoperated cleft palate (UCP) patients were analyzed with computerized aided image system, 20 normal adults were as a control group. Results Showed that maxillary anteroposterior distance of UCP group is shorter than normal control group ( P <0.05) and there is no significant difference on superoinferior distance of jaw between the UCY group and normal control group ( P >0.05). Conclusion The cleft palate intrinsic deformities can interfere maxillarv normal development.
