目的:观察下颌下小切口入路用于髁突颈部骨折复位固定的疗效。方法:纳入研究病例26例,术前确诊为髁突颈部骨折并且具备手术适应证。于下颌角位置做小切口,分离并保护面神经下颌缘支,于该神经上横断咬肌后1/3,骨折断端暴露后,解剖复位并钛板固定。结果:26例患者均恢复正常咬合关系,开口度和开口型均正常,面部对称,无面神经损伤。结论:下颌下小切口入路利用面神经下颌缘支和下颊支之间的解剖间隙,在髁突颈部骨折治疗中效果良好。
Objective: To observe the effect of submandibular small incision approach for reduction and fixation of condylar neck fracture. Methods: Twenty-six cases were included in the study. Preoperative diagnosis of condylar neck fracture with surgical indications. A small incision was made in the position of the mandibular angle to separate and protect the mandibular marginal branch of the facial nerve. One third of the mandibular masseter muscle was transected behind the masseter muscle. After the fracture was exposed, the anatomy was reset and the titanium plate was fixed. Results: Twenty - six patients recovered normal occlusal relationship. The opening degree and open type were normal, facial symmetry and no facial nerve injury. Conclusion: The submandibular small incision approach utilizes the anatomical gap between the facial margin of mandibular branch of the facial nerve and the inferior buccal branch, and has a good effect in the treatment of condylar neck fracture.
