Supratrochlear Nerve Block

Abstract

There has always been confusion regarding whether the symptoms of supraorbital neuralgia are caused by compressive lesions of the supraorbital nerve in isolation, or due to compression of the supraorbital and supratrochlear nerves in combination. Although these two nerves share the sensory innervation of the forehead, the supraorbital nerve is typically held accountable for neuralgic pain in this region. In a prospective study by Pareja and colleagues [1], pain was observed to be limited to the area supplied by the supratrochlear nerve. It offers insights on the best way to distinguish between supraorbital and supratrochlear neuralgia (Table 1).
