喉神经肌蒂移植术,选择好病人是手术成功的基础,其适应征是双侧喉返神经麻痹已一年且无一侧有恢复希望者。患者大多为颈部手术如甲状腺癌或其他病变手术所致。作者分析了200例双侧声带麻痹至少已一年者,有三分之一伴单或双侧环杓关节固定或活动严重受限。此类患者作神经移植毫无意义,确定方法是在全麻下经前连合镜探触的杓状软骨是否固定。触诊器械要放在喉后部,不要放在声带突顶或声带本身。正常声带活动是杓状软骨体向外侧移位,后声门裂明显增大;如环杓关节固定强硬,可能杓状软骨带动喉部一齐移动,可见对侧杓状软骨同时被牵拉,而后声门裂不见增大。触诊器如放在声带或声带
Cholecystectomy in the laryngeal nerve, the choice of a good patient is the basis for successful surgery, and its indications are bilateral recurrent laryngeal nerve paralysis has been one year and no hope to restore one side. Most patients with neck surgery such as thyroid cancer or other lesions due to surgery. The authors analyzed 200 patients with bilateral vocal cord paralysis for at least one year, one third with single or bilateral circumflex joint fixed or severely limited activity. Such patients make no sense of nerve graft, the method is to determine whether the arytenoid cartilage probe under general anterior commissure touches under general anesthesia is fixed. Palpation instrument on the back of the throat, not on the vocal croak or vocal cord itself. Normal vocal cord activity is the arytenoid cartilage shift to the outside, after the osseous cleft significantly increased; such as ring cautious joint fixed hard, arytenoid cartilage may move the throat together, showing the contralateral arytenoid cartilage was pulled at the same time, and then Grosseting did not increase. Palpates such as vocal cords or vocal cords
