甲状腺手术后声嘶的临床分析

Clinical analyse of hoarseness after thyroidecomy

对甲状腺术后声嘶86例临床资料进行分析。结果示86例中声带麻痹37例，其中喉返神经受损31例，喉上神经受损4例，同侧喉上，喉返神经联合性损伤2例；声嘶原因不明49例。认为，甲状腺手术时易损伤喉返、喉上神经而引起嗓音改变，原因不明的声嘶也不能排除该神经的损伤，只是程度较轻水引起声带麻痹。喉神经的损伤与甲状腺肿物的大小无密切关系，但与甲状腺肿物的性质及手术的次数有关。术后3个月内积极治疗并辅以坚持发声训练，声带可恢复正常。

The present paper reports 86 cases of hoarseness after thyroidectomy' In 37 cases,glottic paralysis was confirmed. Among them thp injury of recurrent laryngeal never were 89. 91%(33/37). In 33 (36 side)cases of recurrent laryngeal nerve paralysis,left injury was 20 and right was16. Referring to the literature author consider that: othe recurrent laryngeal nerve was injuredeasy by thyroidectomy because that thyroid gland was located closely with recurrnet laryngealnerve in neck;recurrent laryngeal nerve injury after thyroidectomy was re1ated to the characterof thyroid gland tumor and times of operations;incidence of superior larygeal nerve injure in thy-roidectomy was rare; following up 16 cases of glottic paralysis, most of all (13/16) hoarsenesswas improved with the health side vocal cords overcompensation.
