目的探讨下颌骨喙突骨折手术治疗的更有效方法。方法采用经下颌前庭沟入路,切口在下颌骨外斜线上,切开黏膜、骨膜至第一磨牙,沿骨面剥离下颌支外侧面,达乙状切迹喙突部,显露骨折喙突,分离颞肌附着,摘除喙突。结果手术切口一期愈合,随访6个月～1年,张、闭口正常。结论下颌口内入路摘除骨折喙突,手术相对简单、快速,是治疗下颌骨喙突骨折的有效方法。
Objective To explore a more effective method for the surgical treatment of mandibular coracoid fracture. Methods The mandibular vestibular groove approach was used to incise the external mandibular oblique line. The mucosa and periosteum were dissected to the first molars. The external side of the mandibular branch was dissected along the bone surface and reached the sigmoid notch to expose the coracoid process , Separation of temporal muscle attachment, removal of coracoid process. The results of surgical incision healed, followed up for 6 months to 1 year, Zhang, closed normal. Conclusion The mandibular intra-oral approach to remove the coracoid process is relatively simple and rapid. It is an effective method for the treatment of mandibular coracoid fracture.
