    Abstract:
    Meralgia paresthetica (MP) is a disorder of lateral femoral cutaneous nerve mononeuropathy caused by entrapment or compression of the nerve. It is characterized by numbing, tingling, and burning pain in the lateral aspect of the thigh. The current treatments for MP include conventional medical management, peripheral nerve blocks, and surgical interventions. Some patients who suffer from MP can experience intractable pain and medical management of MP is often inadequate to provide satisfactory pain control. Although regional anesthesia provides excellent pain relief, the analgesic effects of peripheral nerve block are short-lived. Emerging evidence suggests that cryoneurolysis has a low-risk safety profile and can provide prolonged pain relief of superficial nerves when administered appropriately. We present a successful case of a patient with intractable neuropathic pain resulting from MP treated with cryoneurolysis therapy. The patient demonstrated immediate pain relief by 100% after the procedure followed by 80% and 60% pain reduction at 1-month and 3-months follow-up, respectively. Cryoneurolysis may be an alternative modality for patients who fail at conventional medical treatments of neuropathic pain.
