Preoperative and postoperative laryngoscopy should be performed with thyroid operations. A prospective study of 121 thyroid operations from June 1970 to December 1974 was analyzed. There was a 4.2 per cent recurrent laryngeal nerve injury incidence in 217 nerves at risk, four of nine injuries being permanent. Of 217 superior laryngeal nerves at risk, 1.4% were injured, one of three permanently. Previous thyroid operations may place the laryngeal nerves at a greater risk. Transient edema of the laryngeal nerve in 13.4% of the patients was believed due to endotracheal intubation. There seemed to be no difference in the incidence of injury whether the nerves were seen or palpated. It is recommended that indirect laryngoscopy be performed in the course of evaluating thyroid disorders.
甲状腺手术应进行术前和术后喉镜检查。对1970年6月至1974年12月期间的121例甲状腺手术进行了前瞻性研究分析。在217条有风险的喉返神经中，喉返神经损伤发生率为4.2%，9例损伤中有4例为永久性损伤。在217条有风险的喉上神经中，1.4%受到损伤，3例中有1例为永久性损伤。既往甲状腺手术可能使喉神经面临更大风险。13.4%的患者出现喉神经短暂性水肿，认为是气管插管所致。无论神经是被看到还是被触摸，损伤发生率似乎没有差异。建议在评估甲状腺疾病过程中进行间接喉镜检查。
