治疗颅下颌关节强直有多种方法,但任一治疗方式都不能令人完全满意。作者基于强直骨块的形成是病理性反应结果,它不是新生物,无持续生长的能力,解除关节强直不一定要去除强直骨块,而提出了治疗颅下颌关节强直的新观点。 材料和方法 采取向颞部延伸之耳前切口,沿整个升支的宽度,显露强直骨块的侧面及正下方,在强直骨块下正常骨块区行水平截骨。剥离附于下颌升支上的翼肌一嚼肌链,拉开截骨之断端形成间隙,使下颁活动自如,被动开口度不少于3cm。以颞肌 There are several ways to treat cranial mandibular ankylosis, but none of these treatments can be completely satisfactory. The author is based on the formation of ankylosing spondylitis is the result of pathological reactions, it is not a new biological, non-continuous growth ability to lift the ankylosis does not necessarily remove the tendon, and put forward the treatment of cranial mandibular ankylosis of the new point of view. Materials and Methods The anterior anterior incision extending to the temporal area was taken along the width of the entire ascending branch to reveal the lateral and normal portions of the tarsal bone and horizontal osteotomy in the normal bone area under tonic bone. Peeling attached to the mandibular ascending branch of the pterygoid muscle chewing chain, opened the gap to form the gap between the ends of the osteotomy, so that the next move freely, the passive opening of not less than 3cm. To the temporalis muscle
