耳屏前入路治疗下颌骨髁突颈骨折的临床观察

Clinical analysis of condylar neck fracture using preuricular approach

目的:探讨耳屏前入路治疗下颌骨髁突颈骨折的临床观察。方法:对17例采用耳屏前入路行切开复位内固定术的髁突颈骨折患者进行回顾性分析。结果:术后1～2年随访,X线和CT检查骨折愈合良好,17例均获得了良好的咬合关系,15例达到正常的张口度,1例出现张口偏斜,1例术后出现髁突吸收,均没有出现面神经受损和腮腺涎漏等并发症。结论:耳屏前入路治疗髁突颈骨折具有术野暴露好,便于髁突颈复位固定,能够妥善保护面神经,不易发生涎漏等优点。

Objective To evaluate the treatment of a surgical approach for open reduction and internal fixation of condylar neck fracture. Methods A retrospective study was conducted in 17 cases with condylar neck fractures for open reduction and internal fixation using preauricular approach. Results During the follow-up conducted over 1 to 2 years, X-ray and CT examinations revealed good fracture healing. The occlusal relationship and degree and type of mouth opening improved significantly over those before operation, no case of ankylosis and/or salivary fistula was observed. Conclusion Compared with other traditional surgical incision approach, this method can completely expose operative field to facilitate reduction and fixation. In additions, it substantially reduces the risk to the facial nerve and salivary fistula.
