Summary

The International Headache Society (IHS) defines occipital neuralgia, as a unilateral or bilateral paroxysmal, shooting, or stabbing pain in the posterior region of the scalp, in the distribution of the greater occipital nerve (GON), lesser occipital nerve (LON), or third occipital nerve (TON). The condition is occasionally accompanied by diminished sensation or dysesthesia in the affected area and is frequently associated with tenderness over the involved nerves. The majority of cases with occipital neuralgia are idiopathic, with no clearly defined anatomical cause. First, conservative treatment approaches including medication and physical therapy are frequently used. When conservative measures fail to alleviate occipital neuralgia, interventional treatments such as local occipital nerve anesthetic and corticosteroid infiltration, botulinum toxin A injection, occipital nerve subcutaneous neurostimulation or occipital nerve radifrequency treatment may be used.

Interventions

PROCEDURE

Ultrasound-guided proximal greater occipital nerve radiofrequency ablation

In the prone position with the head slightly flexed and the US probe was placed in the neck transversely and then was located the bifid spinous process of C2 and the probe was lateralized (toward the affected side). At this level, the GON is located above the obliquus capitis inferior muscle and deeper than the semispinalis capitis muscle. The in-plane approach from medial to lateral was employed to treat the nerve with a 21 G 5-mm active tip radiofrequency needle. Sensory stimulation was administered at 50 Hz for 1 ms to induce paresthesia, pain, or irritation. A motor stimulus was applied at 2 Hz for 1 ms and up to 2 volts to see if fasciculation was absent. Then 1 mL of 2% lidocaine was administered through the RF cannulas to alleviate procedure related pain. Conventional RFA was conducted for 60 seconds at a temperature of 60 degrees. Following the procedure, 2 mg of dexamethasone was administered per lesion site.
