Neuralgic amyotrophy is a polyneuropathy that classically involves the brachial plexus. This paper reports an unusual clinical manifestation associated with vocal fold paralysis.
A 36-year-old male presented with hoarseness and progressive weakness of the right shoulder and upper arm muscles. Laryngoscopy revealed a limited adduction of the right vocal fold.
Subsequent speech therapy did not improve the symptoms. Therefore, vocal fold augmentation by application of hyaluronic acid in the right vocal fold was performed.
Vocal fold augmentation with resorbable material seems to be a more effective transient treatment than speech therapy alone for patients with neuralgic amyotrophy and laryngeal involvement.
