克氏针治疗下颌骨髁突矢状骨折13例回顾性分析

Retrospective analysis of the treatment of mandibular condylar sagittal fracture with Kirschner wire in 13 cases

目的探讨克氏针内固定方式在下颌髁突矢状骨折治疗中的应用价值。方法回顾分析2019年1月至2020年1月在广州中医药大学附属佛山市中医院口腔医疗中心就诊的下颌骨髁突矢状骨折复位后采用克氏针内固定治疗的患者,共13例19侧。治疗过程包括常规手术切开、暴露并复位游离的下颌骨髁突后,根据下颌骨髁突骨质断端情况利用2~4根克氏针固定,伴发其他部位骨折时同期手术治疗。术后1周通过CBCT评估游离的下颌骨髁突复位精准度及稳固性,通过临床检查评价咬合关系、开口度、开口型。结果所有患者骨折断端对位良好,克氏针无扭曲、折断和松脱;术后咬合关系、开口度、开口型恢复良好。结论克氏针治疗下颌骨髁突矢状骨折效果确切,有临床应用价值。

Objective To evaluate the value of Kirschner wire internal fixation in the treatment of sagittal mandibular condylar fractures.Methods From January 2019 to January 2020,13 patients(19 sides)with mandibular condylar sagittal fracture treated by Kirschner wire internal fixation at the Stomatological Medical Center,Foshan Hospital of Traditional Chinese Medicine were retrospectively analyzed.After conventional surgical incision and exposure and reduction of the mandibular condyle,2-4 Kirschner wires were used for fixation,and other maxillofacial fractures were treated simultaneously.The reduction accuracy and stability of the free mandibular condyle were evaluated by CBCT one week after the operation,and the occlusion relationship,opening degree and opening type were evaluated by clinical examination.Results All patients had good fracture alignment and no twisting,breaking or loosening of the Kirschner wire.The occlusion relationship,opening degree and opening shape recovered well after the operation.Conclusion Kirschner wire is effective in treating sagittal fractures of mandibular condyles.
