Adductor spastic dysphonia is a voice sign associated with various neurologic and psychologic disorders. Treatment of spastic dysphonia in selected patients is unilateral recurrent laryngeal nerve sectioning. Except for voice change or, in some patients, return of phonatory spasticity, there have been no long-term sequelae or complications of this treatment. We describe three patients with adductor spastic dysphonia who underwent recurrent laryngeal nerve sectioning and who, 3 to 38 months later, suffered respiratory distress that required tracheostomy. The respiratory distress in all three patients was due to episodic jerky vocal cord hyperadductions that caused stridor during inspiration and expiration. These repetitive laryngospasms during respiration and phonation were progressive. Two patients needed an arytenoidectomy to achieve a useful voice, and all three required a permanent tracheostomy to alleviate inspiratory laryngeal obstruction.
内收型痉挛性发声障碍是一种与多种神经和心理障碍相关的嗓音症状。对于部分选定患者，痉挛性发声障碍的治疗方法是单侧喉返神经切断术。除了嗓音改变或在某些患者中出现发声痉挛复发外，该治疗方法没有长期后遗症或并发症。我们描述了三名接受喉返神经切断术的内收型痉挛性发声障碍患者，他们在术后3至38个月出现了需要气管切开术的呼吸窘迫。所有三名患者的呼吸窘迫均由发作性急促的声带过度内收引起，吸气和呼气时均出现喘鸣。呼吸和发声时的这些重复性喉痉挛呈进行性发展。两名患者需要进行杓状软骨切除术才能获得有效的嗓音，并且三名患者均需要永久性气管切开术来缓解吸气性喉梗阻。
