Botulinum toxin A for pain reduction in pediatric patients with Parry-Romberg syndrome.

Parry-Romberg syndrome (PRS) is characterized by hemiatrophy of facial structures, including skin, subcutaneous fat, muscle, bone, and cartilage. Complications associated with PRS include headaches, seizures, and chronic facial pain. Protocol for the treatment of chronic facial pain is not clear; reports on the use of botulinum toxin A injections for pain reduction in adults but not in the pediatric/adolescent population are available. Here, we discuss two pediatric PRS cases in which treatment with botulinum toxin A injections reduced or eliminated facial pain.
