下颌骨前脱位常用的复位方法有不足之处。首先由于嚼肌反射性的迅速收缩,有咬伤医生手指的危险;其次,为了克服咀嚼肌肉牵引需要相当大的按力。尽管如此,并不总能达到复位的目的。因此,常常需要采用局麻、全麻或肌肉松弛剂等方法进行复位。 There are shortcomings in the commonly used methods of resetting mandibular anterior dislocation. First, there is a risk of biting a doctor's finger due to the rapidly contracting reflex of the chewing muscle; secondly, a considerable amount of force is required to overcome the masticatory muscle pull. In spite of this, it is not always possible to achieve the purpose of resetting. Therefore, often need to use local anesthesia, general anesthesia or muscle relaxants and other methods to reset.
