Confirmation of Supraorbital Nerve and Its Branch in the Supraorbital Notch with Ultrasound Guidance

Abstract

A 55-year-old female with severe herpes zoster related forehead pain radiating to anterior and posterior scalp visited our pain clinic. The right side forehead pain with numerical rating score of 7 had persisted in spite of antiviral and anticonvulsant medication. We blocked the right supraorbital nerve under ultrasound guidance, and obtained the proper pain relief. In this case, we would like to present the method to identify the supraorbital notch or foramen and possible visualization of the supraorbital nerve.
