Recurrent TMJ Dislocation Managed with Botulinum Toxin Type A Injections in a Pediatric Patient

Chronic recurrent temporomandibular joint (TMJ) dislocation is an uncommon condition that is painful and distressing to patients and uniquely challenging for clinicians. Sustained TMJ dislocation is not amenable to manual reduction alone when the etiology is muscular in nature. The purpose of this report was to describe the case of a child presenting with recurring temporomandibular joint dislocation secondary to muscle hyperactivity of unknown etiology that was managed with injections of botulinum toxin type A into the inferior lateral pterygoid muscles. The use of this peripheral antispasmoic neurotoxin is a reasonable, safe, and conservative, palliative treatment option for pediatric patients suffering from chronic recurring TMJ dislocation.
