The lesser occipital nerve (LON) is commonly injected alongside the greater occipital nerve for headache disorders.

Procedure

Landmark guided

• The procedure is similar to the the greater occipital nerve injection
• Locate the LON by going two-thirds of the way between the occipital protuberance and the mastoid process.
• Enter perpendicular to the skip, stop at the periosteum.
• Aspirate gently and then inject.
