Efficacy of the Accent Method of Voice Therapy in Professional Voice Users with Minimal Associated Pathological Lesions of the Vocal Folds.

AIMS: Minimal associated pathological lesions (MAPLs) of the vocal folds are a group of benign disorders commonly related to phonotraumatic conditions and behaviors. Voice therapy (VT) can play a major role in readjusting these maladaptive behaviors and improve overall voice quality, thereby replace surgical intervention in some cases or act as a complementary treatment to enhance the ultimate therapeutic outcomes. This study aims to explore the short-term effect of the Accent method of VT on vocal subjective measures and acoustics in professional users with MAPLs, evaluate the responsiveness of each vocal fold lesion to the VT, and propose a simple model for providing VT to a sector of the population in great need of non-invasive management.

MATERIALS AND METHODS: This analytical cross-sectional included fifty professional voice users with different MAPLs were exposed to multidimensional voice assessments before and after receiving VT training in a tertiary care hospital. These assessments include GRBAS score, Multidimensional Voice Program (MDVP) and validated Arabic version Voice Handicap Index (VHI-30).

RESULTS: This study showed variable positive effects of VT on the different types of MAPLs. Cysts had the highest level of responsiveness to VT in comparison to other lesions, followed by nodules, polyps, contact granuloma, and Reinke's edema.

CONCLUSIONS: VT is a substantial solution for managing voice disorders. It should be considered in the management plan of the various types of MAPLs, even in Reinke's edema, which showed the minimum improvement.
