We describe a new etiology for vocal cord paralysis. Two patients, chronic drug abusers, had in time lost access to the usual peripheral veins, and proceeded then to have the drugs injected repeatedly into the jugular veins in the neck. Both presented with persistent hoarseness and were found to have a unilateral vocal cord paralysis. Neck exploration was undertaken to evaluate this pathology, to rule out other obscure disease, and to decompress the recurrent laryngeal nerve within the carotid sheaths. Severe fibrosis was encountered in the neck of one patient and mild fibrosis in the other. A biopsy specimen from the adjacent autonomic portion of the vagus nerve was submitted. Although the follow-up period was short, no definite return of function was observed. A discussion of injection injuries to nerves is presented.
我们描述了一种声带麻痹的新病因。两名慢性药物滥用者，随着时间推移，其常用的外周静脉无法再用于注射，于是开始反复将药物注射到颈部的颈静脉中。两人均出现持续性声音嘶哑，经检查发现单侧声带麻痹。为评估该病变、排除其他隐匿性疾病并对颈动脉鞘内的喉返神经进行减压，进行了颈部探查。其中一名患者颈部出现严重纤维化，另一名患者为轻度纤维化。取自迷走神经相邻自主神经部分的活检标本被送检。尽管随访期较短，但未观察到明确的功能恢复。本文还对神经注射损伤进行了讨论。
