改良甲状软骨成形术治疗单侧声带麻痹

Modified type Ⅰ thyroplasty for treating unilateral vocal cord paralysis

目的研究单侧声带内收麻痹的手术治疗新方法。方法对5例不同病因所致单侧声带麻痹患者,采用改良Ⅰ型甲状软骨成形术进行治疗。术前、术后行频闪喉镜及电声门图检查。结果术后喉像显示5例患者的患侧声带不同程度由旁正中位移至或接近中线位,发声时声门闭合已恢复;电声门图波形接近正常人,主观听觉声音基本正常或明显好转。结论改良Ⅰ型甲状软骨成形术是治疗单侧声带麻痹的一种简单实用、安全有效方法。

Objective To explore a new surgical approach for treating unilateral vocal cord paralysis. Methods Five cases of unilateral vocal cord paralysis due to various causes were treated with modified typeⅠthyroplasty. Laryngostroboscopy and electroglottography were performed before and after the operations. Results The vocal cords were shifted very close to the median line in all the 5 cases postoperatively as shown by laryngostroboscopy and electroglottography. Complete closure of the glottis was achieved. The patients had almost normal results of electroglottography, and the vocal sound nearly recovered normal or was significantly improved. Conclusion Modified typeⅠthyroplasty is effective, safe and easy in treating unilateral vocal cord paralysis.
