下颌后小切口结合肿胀分离技术在髁突低位骨折内复位固定术中的应用

目的:探讨应用下颌后小切口及肿胀分离技术在髁突低位骨折切开复位内固定术中的应用效果。方法:对36例下颌骨髁突低位骨折患者采用下颌后小切口,术区皮下行肿胀液注射后紧贴皮下分离至咬肌表面,平行于面神经的方向钝性分离咬肌纤维,显露骨折部位,直视下行髁突骨折解剖复位内固定术。结果:术后通过临床及影像学检查随访,复位固定效果满意,无面神经损伤等严重并发症,切口瘢痕隐蔽。结论:下颌后小切口结合皮下肿胀分离技术处理髁突低位骨折具有安全、便捷、美观的优点,值得临床推广。

Application of open reduction and internal fixation on low condylar fractures by mini-retromandibular approach combined with tumescent separation technique

Objective To evaluate the clinical results of open reduction and internal fixation on low condylar fractures using a mini-retromandibular approach combined with tumescent separation technique.Methods A mini-retromandibular incision was performed for 36 patients with low condylar fracture.The subcutaneous tissue flaps were dissected to masseter muscle after operating field were infiltrated with tumescent solution,the masseter muscle fibres were then blunt dissected paralleling the facial nerve fibres.The fracture field was expoesed and identified,and the straightforward reduction and internal fixation of condylar fractures were performed.Results Through clinical and radiologic postoperative examinations,satisfactory results were obtained with no serious complications such as facial nerve injury.The surgical scars were barely noticeable.Conclusion Combined with subcutaneous tumescent solution infiltration technique,the mini-retromandibular access proved to be a safe,convenient,and cosmetic approach which has been routinely performed in our department.
