Botulinum toxin type a improves pain in numb chin syndrome

We describe a case of bilateral numb chin syndrome, secondary to Burkitt lymphoma, associated with refractory and persistent burning neuropathic pain, effectively treated twelve times with subcutaneous Botulinum toxin type A (BoNT/A) injections. The procedure was well tolerated, but the patient reported incomplete mouth closure of minimal entity. BoNT/A could be a safe and effective therapy for neuropathic pain associated with numb chin syndrome.PMID:38159684 | DOI:10.1016/j.toxicon.2023.107565
