Vocal fold palsy is a cause of dysphonia. Due to incomplete glottic closure during phonation, patients with a unilateral vocal fold palsy present with a weak and breathy voice and recurrent aspiration. To lessen the clinical manifestations of unilateral vocal fold palsy, polytetrafluoroethylene (Teflon) paste is one agent which has been injected into the paraglottic region, thus causing the vocal fold to move more medially. One of the complications associated with Teflon paste injection is migration of the paste into the surrounding tissues. We present a patient with idiopathic left vocal fold palsy who underwent Teflon injection to the vocal fold and subsequently developed a precricoid nodule, mimicking a cartilaginous swelling.
声带麻痹是声音嘶哑的一个原因。由于发声时声门闭合不全，单侧声带麻痹患者表现为声音微弱、带呼吸声以及反复误吸。为减轻单侧声带麻痹的临床表现，聚四氟乙烯（特氟龙）糊剂是一种已被注入声门旁区域的药物，从而使声带更向内侧移动。与特氟龙糊剂注射相关的并发症之一是糊剂向周围组织迁移。我们报告一例特发性左侧声带麻痹患者，其接受了声带特氟龙注射，随后出现环状软骨前结节，酷似软骨肿胀。
