The use of botulinum toxin B in the treatment of a post-traumatic sialocele in a 4-year-old child: A case report.

Parotid sialoceles are bothersome complications of parotidectomy and penetrating injury to the parotid gland. Though typically self-limited and responsive to conservative management, they can be particularly difficult to manage in the pediatric population where even conservative interventions are less well tolerated. We present the case of a 4-year-old child with a post-traumatic parotid sialocele that was successfully managed with a single injection of botulinum toxin B. To our knowledge, this is the first reported case of the use of botulinum toxin for this purpose in the pediatric population.
