急性颞颌关节前脱臼是常见的,但持久性脱臼並不常发生。颞颌关节脱臼如不及早复位,则肌肉痉挛将使以后的复位困难。如躭阁时间过长,由于关节凹部分被纤维组织所填充,复位后髁突有时不能保持在关节窝内。以往报告过的持久性颞颌关节脱臼的病例大多数用外科方法治疗。可是,外科手术不能保存颞颌关节的正常解剖关系。本文报告一例下颌前脱臼15个月后用咬(牙合)垫并上下颌牵引的保守方法治疗成功。因此,在考虑外科手术之前可试用这种保守方法。
Acute temporomandibular joint dislocation is common, but permanent dislocation does not occur. Temporomandibular joint dislocation if not reset as soon as possible, the muscle spasm will make the reset later difficult. If the 躭 Court time is too long, because the concave part of the joint was filled with fibrous tissue, the condyle sometimes can not remain in the socket after resetting. Most of the reported cases of persistent temporomandibular joint dislocation have been treated surgically. However, surgery can not preserve the normal anatomy of the temporomandibular joint. This article reports a successful treatment of a conservative approach to bite (occlusion) pad and upper and lower jaw traction 15 months after mandibular dislocation. Therefore, consider this conservative approach before surgery.
