Transient or permanent recurrent laryngeal nerve palsy is a well known complication in thyroid surgery with reported incidences of 5-8% and 1-3%, respectively (1). Diplegia has an incidence of 0.4% (2). Inflammatory bowel disease (IBD) is an important cause of peripheral neurosensitivity, particularly autonomic neuropathy, which can lead to transient or permanent laryngeal nerve palsy when neural structures are involved during surgery. Several mechanisms have been implicated in the physiopathology of these neurological disorders, but the actual mechanism is still unknown. Herein we report on two patients with IBD presenting with transient bilateral recurrent laryngeal nerve palsy after total thyroidectomy without any evident mechanical or traumatic manoeuvres on apparently preserved nerves.
暂时性或永久性喉返神经麻痹是甲状腺手术中已知的并发症，其发生率分别为 5-8%和 1-3%（1）。双侧喉返神经麻痹的发生率为 0.4%（2）。炎症性肠病（IBD）是周围神经敏感性的重要原因，特别是自主神经病变，当手术中涉及神经结构时，可导致暂时性或永久性喉返神经麻痹。这些神经病变的病理生理学涉及多种机制，但实际机制尚不清楚。在此，我们报告两例 IBD 患者，在甲状腺全切除术后出现短暂性双侧喉返神经麻痹，而神经在外观上保持完好，没有明显的机械或创伤操作。
