下颌骨髁突骨折手术与非手术治疗的对比研究

Anatomical and Functional Studies on Surgical and Non-surgical Treatment of Mandibular Condylar Process Fractures

目的 :比较髁突骨折手术治疗和非手术治疗的疗效。方法 :49例下颌骨髁突骨折患者 ,2 2例采用手术治疗 ,2 7例采用非手术治疗 ;治疗后 6周和 1年复诊 (6周失访率为 14 3% ,1年失访率为 30 6 % ) ,通过临床和X线片检查来测定两组患者的髁突移位角度和张口度 ,分析开口偏斜和咀嚼功能情况。结果 :治疗前手术治疗组的髁突平均移位角度显著大于非手术治疗组 ,但治疗后 6周和 1年 ,手术组的髁突移位角度和开口偏斜率显著小于非手术组 ,手术组的咀嚼功能优于非手术组 ;6周时手术组的张口度明显大于非手术组 ,1年后两者相近。结论 :对伴有移位或错位的髁突骨折 。

Objective:This study aim at comparing anatomical and functional recovery from surgical and non_surgical treatment of condylar process fractures. Methods: Totally Forty_nine patients, 22 treated by performing operation, and 27 using non_surgical methods, were included in this study. Displaced angle of condylar, maximal mouth opening, lateral deviation on opening and masticatory function were analyzed using radiological and clinical examinations 6 weeks and 1 year after treatment.Results: Patients treated by surgical method had significantly greater initial displaced angle of condyles than did the group treated non_surgically, but patients treated non_surgically had significantly greater displaced angle of condylar and lateral deviation on opening than did the group treated surgically 6 weeks and 1 year after the therapy finished. Patients treated surgically had significantly greater masticatory function than did the group treated non_surgically 6 weeks and 1 year after treatment. Six weeks later, patients treated surgically had significantly greater maximal mouth opening than did the group treated non_surgically.Conclusion:Surgical treatment may be helpful in anatomical and functional recovery of mandibular condyles for patients with displaced condylar process fractures.\;
