目的评估改良杓状软骨内收术治疗单侧声带麻痹的疗效.方法回顾性分析2001年2月～2007年12月22例行改良杓状软骨内收术的单侧声带麻痹患者的临床资料,对术前和术后3个月的误吸指数、主观听感知评估参数(GRBAS)、声学检测参数[基频(F_0)、基频微扰(jitter)、振幅微扰(shimmer)、标准化噪声能量(NNE)]、最大声时(MPT)、平均气流率(MFR)进行统计学分析.结果 22例患者术后误吸指数分值较术前明显下降,GRBAS评估各参数比术前明显下降,声学检测各参数(F_0、jitter、shimmer、NNE)较术前明显降低,最大声时明显延长,平均气流率明显降低,差异均有统计学意义(均为P<0.001).结论改良杓状软骨内收术是一种治疗单侧声带麻痹有效的声带内移术,既可恢复良好的发声功能,又可缓解误吸.

Objective To evaluate the efficacy of modified arytenoid adduction in the management of patients with unilateral vocal fold paralysis(UVFP).Methods A retrospective review was performed on 22 patients who underwent modified arytenoid adduction for UVFP between February 2001 and December 2007.Pre-,and 3 months postoperative aspiration,perceptual(GRBAS),acoustic data(fundamental frequency,F_0,fundamental frequency perturbation,jitter,amplitude perturbation,shimmer,normalized noise energy,NNE)and aerodynamic(maximal phonatory time,MPT,mean airflow rate,MFR)were analyzed statistically.Results The ratings of postoperative aspiration were significantly decreased than that of the preoperation(P<0.0001).There was a significant decrease in GRBAS scales postoperatively versus preoperatively(P<0.0001).The mean values of voice acoustics parameters (F_0,jitter,shimmer,NNE)were significantly decreased,the maximum phonation time were significantly longer,and the mean airflow rate were significantly decreased after operation than that of the preoperation(P<0.001).Conclusion Modified arytenoid adduction is an effective medialization technique that can restore satisfactory speech and prevent aspiration in patients with UVFP.
