To describe a relatively simple, easy, and safe technique for open reduction and internal fixation of the mandibular angle fracture using the combined modified percutaneous and oral approach with no special instrumentation.
This study was carried out on 10 patients who had traumatic mandibular angle fractures. All patients were managed by open reduction and internal fixation. Intraoral exposure and reduction of the fracture was performed through the gingivolabial incision. Then, a modified percutaneous-transbuccal way was utilized for conduction of the microdrill shaft and screw driver to permit screws fixation with perpendicular relations between plate and inserted screws.
There were no registered soft tissue infections, wound dehiscence, occlusal defects, or facial nerve paresis. The mean surgical duration was 39.7 ± 11.5 minutes. No patients were recorded to have unsatisfactory external scar and further intervention was not required.
The described percutaneous approach to mandibular angle fracture can be done effectively and safely using available and operatively fabricated disposable tools.
描述一种相对简单、易行且安全的技术，即采用改良经皮与口腔联合入路，无需特殊器械，对下颌角骨折进行切开复位内固定。
本研究对10例创伤性下颌角骨折患者进行。所有患者均接受切开复位内固定治疗。通过龈唇切口进行口腔内骨折暴露与复位。然后，采用改良经皮穿颊方式引导微型钻杆和螺丝刀，以便在钢板与植入螺钉之间呈垂直关系的情况下进行螺钉固定。
未出现软组织感染、伤口裂开、咬合缺陷或面神经麻痹的记录。平均手术时长为39.7 ± 11.5分钟。未记录到患者有外观瘢痕不满意的情况，无需进一步干预。
使用现有的可手术制作的一次性工具，所描述的经皮治疗下颌角骨折的方法可以有效且安全地完成。
