Postherpetic neuralgia is one of the more common sequelae of herpes zoster, and the treatment modalities of facial herpes zoster postherpetic neuralgia include medication and minimally invasive interventional therapy.
1. Medication: medication is the most basic and commonly used method, and the commonly used medications include pregabalin, gabapentin, and 5% lidocaine patches.
Gabapentin and Pregabalin are calcium channel modulators, which can reduce the excessive release of excitatory neurotransmitters, thus relieving pain. Lidocaine is a local anesthetic that exerts analgesic effects by blocking voltage-dependent sodium channels and reducing abnormal impulses generated by primary afferent nerve pain receptors.
2. Minimally invasive interventional therapy: Patients who are ineffective in drug therapy can undergo minimally invasive interventional therapy such as facial nerve block, nerve destruction, pulsed radiofrequency and ozone therapy under ultrasound or CT guidance.
Patients with postherpetic neuralgia of the face should go to the hospital in time, under the guidance of the doctor in time to carry out standardized treatment, and early relief of the patient’s pain. The medication should be in accordance with the doctor’s prescription.
