Objective:
This study aims to examine the effect of voice therapy on dysphonia on children with benign vocal fold lesions, as measured by perceptual evaluation using the Consensus Auditory Perceptual Evaluation of Voice (CAPE-V) and acoustic and aerodynamic measures (jitter, shimmer, noise-to-harmonic ratio, phonation threshold pressure, mean airflow during voicing, subglottic pressure during comfortable phonation).
Study Design:
Prospective disease-specific outcomes database.
Methods:
Subjects identified in the database consisted of 28 children (14 male, 14 female) between the ages of three and eighteen. Pre- and post-therapy perceptual, acoustic and aerodynamic measures were compared using two-sided paired t-test.
Results:
There was a statistically significant difference in perceptual ratings of voice quality (p < .001) and in phonation threshold pressure before and after therapy (p = .034). While acoustic measures improved after therapy, changes were not statistically significant.
Conclusions:
Children with dysphonia secondary to benign vocal fold lesions showed positive change in perceptual ratings of voice quality and in phonation threshold pressure after voice therapy.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
