颌后切口横断腮腺入路治疗髁突中低位骨折

Retromandibular Transverse Transparotid Approach in Middle and Low-set Mandibular Condylar Fracture by Rigid Fixation

目的研究颌后切口横断腮腺横入路切开复位固定中低位髁突骨折的临床效果.方法 55例成人髁突中低位骨折采用颌后切口横断腮腺横入路进行骨折复位并坚强内固定,分别观察术中操作情况以及术后患者张口度、张口型、咬关系、涎瘘、面神经症状以及颞下颌关节症状等.结果颌后切口横断腮腺横入路手术的患者术后骨折复位愈合,面形及咬关系均恢复良好.结论颌后切口横断腮腺横入路手术治疗髁突中低位骨折有效、可行.

Objective To explore the clinical effect of retromandibular transverse approach in middle and low-set mandibular condylar fractures by rigid fixation.Methods 55 adult patients with condylar fractures were treated by the retromandibular transverse transparotid approach.Rigid internal fixation was performed by means of miniplate fixation.The occurrence of surgical and functional complications,such as fracture healing,mouth opening,ccclude,mandibular movements,injury of facial nerve,facial symmetry,temporomandibular joint,et al,were documented both during hospitalization and 1,3,6,9,12 months after surgery.Result All patients treated by the retromandibular vertical transparotid approach were satisfied with postoperative wound healing,facial features and occluding relation.Conclusion It is suggested that the retromandibular transverse transparotid approach offers a n effective approach in middle and low-set mandibular condylar fractures for direct fixation.
