Objective: The aim of this study was to identify effect of endolaryngeal phonomicrosurgery (EPM) in patients with vocal fold polyps on the acoustic parameters of voice by comparing their voice samples before and after EPM, with that of control group.
Methods: The acoustic tests of voice were carried out on 37 female patients with vocal fold polyp before the endolaryngeal phonomicrosurgical intervention (EPM) and after its completion. Acoustic parameters of voice were compared with the control group without voice pathology. The results of the investigation were analyzed acoustically.
Results: It has been proved that jitter (%), shimmer (%), vFo, VTI, PPQ, APQ and HNR values significantly differentiate the patients with polyps of vocal fold from control group without pathological changes in the larynx. All of the analyzed parameters improved significantly after the phonomicrosurgical intervention and tend to approach normal values.
Conclusion: The acoustic analysis of voice may be used for evaluation of the presurgical and postsurgical voice status.
