Trigeminal Neuralgia With Extraoral Trigger Zone Successfully Treated With Intraoral Injections of Botulinum Toxin: A Case Report.

Trigeminal neuralgia is a pain condition that is frequently misdiagnosed and challenging to manage. We present the case of a patient with trigeminal neuralgia with multiple misdiagnoses and poorly managed pain. Despite the presence of trigger zones both inside and outside her mouth, complete symptom resolution was ultimately achieved through onabotulinumtoxinA injections, delivered solely intraorally.
