Trigeminal neuralgia is a recurrent facial throbbing pain, also known as “painful spasms” because of its severity. It is usually seen in middle-aged and elderly people over 50 years old. It is called secondary trigeminal neuralgia if the cause is clear, and primary trigeminal neuralgia if the cause is unknown. The treatment of trigeminal neuralgia is mainly divided into medication, closure (nerve block) treatment, surgery and other treatments. 1.Medication: The treatment of trigeminal neuralgia mainly adopts antiepileptic drugs, of which carbamazepine is the drug of choice. If it is ineffective or there are intolerable side effects, other antiepileptic drugs can be chosen, and anti-convulsant drugs or dopamine receptor blockers can also be chosen. To promote nerve repair, B vitamins may also be given. 2.Closure (nerve block) therapy: For the ineffectiveness of drug therapy or the emergence of obvious side effects, nerve block therapy can be used. The main principle of treatment is to make the area near the disease completely numb, to achieve the purpose of pain relief. There are mainly supraorbital nerve block, maxillary nerve block, posterior superior alveolar nerve block, infraorbital nerve block, mandibular nerve block, and upper and lower alveolar nerve block. 3.Surgical treatment: For those patients who suffer from long-term pain and seriously affect the quality of survival and physical health, surgical treatment should be considered. Including nerve avulsion (trigeminal neurectomy), radiofrequency temperature-controlled thermocoagulation, microvascular decompression, etc. 4.Other treatments. Including tissue therapy, physical therapy, cryotherapy, etc. Trigeminal neuralgia is a kind of episodic sudden and severe pain, and it has good effect on the treatment of carbamazepine and nerve block. If recurrent episodes of throbbing pain in the face occur, you should promptly seek medical diagnosis and treatment, and use the medication under the guidance of the doctor’s advice.
