Background:
Velopharyngeal dysfunction produces a nasal speech pattern because of the inability to close the nasal airway during speech, most often associated with anatomical abnormalities of the palate.
Case Report:
We describe two cases of possible velopharyngeal dystonia, a task-specific movement disorder causing a speech pattern similar to velopharyngeal dysfunction. Both patients experienced treatment response with anticholinergic medication.
Discussion:
Dystonia affecting speech via involvement of the pharyngeal musculature may be an unrecognized etiology of voice disorders.
