Figure 6: The GON can be identified through blunt dissection laterally between the top surface of the semispinalis capitis and underneath the trapezius fascia. Following identification, a vessel loop is used to provide gentle traction on the nerve. A 1 x 1 cm block of the semispinalis muscle medial to the emergence of the GON is excised. The image above illustrates nerve release after excision
