目的评价咬合夹板保守治疗儿童髁突矢状骨折的疗效。方法回顾性分析1991年1月至2011年12月，解放军总医院口腔颌面外科收治儿童髁突矢状骨折患者39例（48侧），采用咬合夹板行保守治疗3—6个月，观察患者磨牙区咬合增高后下颌活动度、开口型，并行CT检查观测髁突形态改建情况。结果29例患者下颌功能恢复良好，6个月时平均开口度〉35mm，11例开口时下颌偏斜，CT检查显示28例（32侧）患者髁突形态改建良好，11例（16侧）患者髁突部分改建。结论咬合夹板保守治疗儿童髁突矢状骨折是一有效方法。

英文摘要：

Objective To investigate the clinical resuhs of occlusal splint in the treatment of sagittal fracture of mandibular condyle （SFMC） in children. Methods Thirty-nine patients （48 condyles） aged 3-8 years with sagittal fracture of mandibular condyle were included in this study. All the patients were treated by occlusal splint. Slight open occlusion was maintained by occlusal splint for 3-6 months. Clinical and radiological examination was performed six mouths and every year after treatment. Results Good mandibular function was observed in 39 patients. Maximal mouth opening over 35 mm was achieved at 6 months. But 11 of the 39 patients presented with deviation on mouth opening at 6 months. The radiology showed an complete remodeling in 32 condyles （28 patients ） and partial remodeling in 16 condyles （ 11 patients）. Poor remodelling was not observed in any patients. Conclusions Good clinical results can be obtained by using occlusal splint in the treatment of pediatric sagittal fracture of mandibular condyle.
