Thanks for sharing your question. I canappreciate your concern.Trigeminal neuralgia is the consequence of piercing musclesaround the face on branches of the trigeminal cranial nerve. ( a sensory nerveof the face). Botox which paralyzes the muscles, have being approved for theuse of migraine headaches for this main reason. Depending on the location of your neuralgia, botox shouldhelp with the symptoms. On the same token, surgery in this area will stretch yournerves, creating a temporary numbness to the nerves. You may experiencepotential improvement to the areas where the surgery is performed. Make sure to have an evaluation by a board certified plasticsurgeon who has experience in facial cosmetic surgery and migraine surgery.Best wishes
Theoretically there shouldn't be a link; however, you don't know the trigger for your neuralgia and I would strongly recommend you avoid all elective facial procedures, especially cosmetic as it may trigger the neuralgia.
