Summary
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.
