下颌骨髁突骨折手术与非手术治疗的对比研究

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,22例采用手术治疗, 27例采用非手术治疗;治疗后6周和1年复诊(6周失访率为1413%,1年失访率为3016%),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,手术治疗后的髁突解剖复位和功能恢复均优于非手术治疗。

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

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.;
