title: Spasmodic dysphonia in an adolescent patient with an autoimmune neurologic disorder.
abstract: Pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS) has been primarily described in the neurology and psychiatry literature. The symptoms of this syndrome typically are a range of obsessive compulsive disorders and neuromuscular tics. The otolaryngologist occasionally becomes involved with these children when it is deemed that chronic tonsil infections are the source. We report here on a child diagnosed with PANDAS who presented with severe ventricular hyperfunction and adductor spasmodic dysphonia. She was treated with botulinum toxin, which resulted in a significant improvement in subjective voice as well as reduced jitter and shimmer on objective voice measurements.
