Abstract

[INTRODUCTION] Functional dysphonia occurs in the absence of structural or neurologic laryngeal abnormalities with various manifestations including aphonia and inappropriate vocal pitch. Voice therapy is the first-line treatment, and literature on treatment options for functional dysphonia unresponsive to voice therapy is limited.

[METHODS] Retrospective medical records review and report of a case.

[RESULTS] We report a unique case of an adult male with recalcitrant high-pitched functional dysphonia of adult-onset that was successfully treated with a single cricothyroid muscle botulinum toxin (Botox) chemodenervation injection.

[CONCLUSION] Cricothyroid muscle botulinum toxin chemodenervation can be an effective treatment for recalcitrant functional dysphonia.
