目的评估下颌角截骨术对患者咀嚼效率的影响。方法选择15例拟行下颌角截骨术（下颌角下颌缘切除合并下颌体部外侧骨皮质劈除术）患者，排除牙周疾病、颞下颌关节疼痛及偏颌等疾病，采用杏仁、小枣过筛称重法，分别测量患者术前、术后1个月及术后6个月的咀嚼效率。结果患者术后1个月与术前相比咀嚼效率明显减小，差异有统计学意义；术后6个月与术后1个月相比，咀嚼效率明显增大，差异有统计学意义；术后6个月与术前相比，差异无统计学意义。结论下颌角截骨术对患者的咀嚼效率无明显影响。

Objective To evaluate the masticatory efficiency after mandibular angle ostectomy. Methods Fifteen patients who accepted mandibular angle ostectomy (bilateral jaw edge of the mandibular angle resection and mandibular body outer panel split) were selected. Periodontal disease, temporomandibular joint pain and partial jaw were screened. The masticatory efficiency of the patients were evaluated by means of sieving and weighing almond and jujube before operation, 1 month and 6 months after operation. Results There were significant differences between the average masticatory efficiency 1 month after operation and before operation (P<0.05) or 6 months after operation (P<0.05). There was no difference between the average masticatory efficiency before operation and 6 months after operation (P>0.05). Conclusion Mandibular angle ostectomy has no effect on the masticatory efficiency.
