하악각 골절에 있어서 평판대 형성기법

Abstract

There are various surgical fixation techniques for fractures of the mandible angle due to traumatic facial injuries. Among those surgical treatment modalities, fixation methods using plates, screws, lag screws and wires have been commonly used. With the introduction of absorbable plates, the plate fixation technique has been popularized. However, plate fixation requires an external incision or an external approach using trochar for the direction of screw fixation to be perpendicular to the mandible. The external approach has disadvantages in that it leaves a scar and involves some risk to damage the marginal mandibular branch of the facial nerve. To overcome these disadvantages, the authors used a plate platform formation technique on the fractured mandible angle. The result was satisfactory with no complications. Plate platform formation technique, as performed by the authors, can be a new and simple surgical technique for stable fixation and with minimal postoperative complication by an internal approach to avoid an external scar and nerve injury.
