Abstract:
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.
