Treatment of mandibular condylar fractures is not standardized. The maxillomandibular cortical bone screw fixation technique carries many advantages. The aim of this work was to evaluate this technique for routine method.
Fifty patients treated by maxillomandibular fixation (MMF) by use of cortical bone screws from 2004 to 2006 were retrospectively analyzed. In our maxillofacial surgery unit in Bordeaux, France, our indication is to treat extra-articulated fractures without severe displacement by MMF.
The mean time required for MMF was 13 minutes, and fixation occurred after a mean of 16 days. Screw removal was performed after a mean of 26 days, and this required local anesthesia. Of the patients, 48 had good occlusion. Two patients had persistent lateral cross bites. Two patients had mandible deviation when they opened their mouths, and mouth opening was limited in one patient. Two patients had temporomandibular joint pain.
MMF screws have more advantages and fewer disadvantages than arch bars when closed treatment has been selected as the treatment of choice.
下颌髁突骨折的治疗尚无标准化方法。上颌下颌皮质骨螺钉固定技术具有诸多优势。本研究旨在评估该技术作为常规方法的效果。
回顾性分析2004年至2006年期间采用皮质骨螺钉进行上颌下颌固定（MMF）治疗的50例患者。在法国波尔多的我们的颌面外科科室，我们的适应证是采用MMF治疗无严重移位的关节外骨折。
MMF平均所需时间为13分钟，平均16天后完成固定。平均26天后进行螺钉取出，这需要局部麻醉。48例患者咬合良好。2例患者持续存在侧向交叉咬合。2例患者张口时出现下颌偏斜，1例患者张口受限。2例患者有颞下颌关节疼痛。
当选择闭合治疗作为首选治疗方法时，MMF螺钉相较于牙弓夹板具有更多优势且劣势更少。
