摘　　要：BACKGROUND Primary trigeminal neuralgia can achieve satisfactory results through clinical treatment and intervention.The pathogenesis of neuralgia caused by varicellazoster virus infection of the trigeminal nerve is more complex,and it is still difficult to relieve the pain in some patients simply by drug treatment or surgical intervention.CASE SUMMARY A 66-year-old woman was hospitalized with herpetic neuralgia after herpes zoster ophthalmicus(varicella-zoster virus infects the ophthalmic branch of the trigeminal nerve).On admission,the patient showed spontaneous,electric shocklike and acupuncture-like severe pain in the left frontal parietal region,and pain could be induced by touching the herpes area.The numerical rating scale(NRS)was 9.There was no significant pain relief after pulsed radiofrequency and thermocoagulation of the ophthalmic branch of the trigeminal nerve.Combined with patient-controlled intravenous analgesia(PCIA)with esketamine,neuralgia was significantly improved.The patient had no spontaneous pain or allodynia at discharge,and the NRS score decreased to 2 points.The results of follow-up 2 mo after discharge showed that the NRS score was≤3,and the Pittsburgh Sleep Quality Index score was 5 points.There were no adverse reactions.CONCLUSION Trigeminal extracranial thermocoagulation combined with esketamine PCIA may be a feasible method for the treatment of refractory herpetic neuralgia after herpes zoster ophthalmicus.
