下颌下小切口入路行髁突颈部骨折复位固定术的疗效观察

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。

Surgical treatment of mandibular condylar neck fracture with submandibular small incision approach

PURPOSE： To evaluate the efficacy of submandibular small incision tbr treatment of condylar neck fracture. METHODS： The study included 26 cases with preoperative diagnosis of condylar neck fractures who needed surgical therapy. A small incision was performed in the mandibular angle, followed by separation and protection of the marginal mandibular branch of facial nerve, the posterior 1/3 of the masseter muscles were incised. After exposure of the fractures, anatomical reduction and titanium plate fixation were conducted. RESULTS： All patients returned to normal occlusion, and mouth opening was normal. There was no facial nerve injury among all patients. CONCLUSIONS： Good results were gained with submandibular approach using the space between marginal mandibular branch and inferior buccal branch of the facial nerve in patients suffering from condylar neck fractures.
