Trigeminal neuralgia is an episodic severe pain that occurs in the patient’s head and face. The pain is intermittent and is intense with electric shock-like and tearing pain. In the past, treatment of trigeminal neuralgia required an incision behind the ear in the head to separate the nerve from the blood vessels in the brain and a pad between the nerve and the blood vessels, which was a risky procedure with a high recurrence rate and not easily accepted by patients. The trigeminal nerve hemimelia thermal coagulation radiofrequency surgery developed in recent years can cure trigeminal neuralgia without an incision and with only a fine needle of 1 mm in diameter and a needle eye. The trigeminal neuralgia treatment with trigeminal nerve hemianoplasty, created by Prof. Zheng Baosen of our hospital, is a pioneer in the minimally invasive treatment of trigeminal neuralgia, with a fine needle and a small eye, the severe pain disappears instantly.
