Objectives: Treatments for unilateral vocal fold paralysis (UVFP) include conservative voice rehabilitation, vocal fold injection, and laryngeal framework surgery. We proposed basic fibroblast growth factor (bFGF) injection as a potential novel treatment for UVFP and have reported the short-term results. In this study, we present the long-term results and safety of vocal fold bFGF injection as a treatment for UVFP.

Background: Benign vocal fold lesions (BVFLs) can cause voice changes, including reduced loudness and pitch range. In recent times, with progression in endoscopic technology, office-based vocal fold steroid injection (VFSI) has been used as an alternative therapy for BVFLs.

Aims/objectives: In this study, we analyzed the efficacy and safety of VFSI to investigate the mechanism underlying its therapeutic effects and determine the conditions in which VFSI will be most effective.

Purpose: Speech fundamental frequency (SFF) assessment is essential for all dysphonia patients to effectively evaluate the therapeutic effects of voice therapy, especially in patients with disturbances in their voice pitch due to mutational dysphonia, Reinke's edema, or as side effects of hormone therapy. A standard method of SFF measurement remains unknown. Speech tasks such as sustained vowel phonation, counting, reading passage, and spontaneous speech have generally been used for SFF measurements.
