Trigeminal autonomic cephalalgias (TACs) are a group of highly disabling primary headache disorders. Although pharmacological treatments exist, they are not always effective or well tolerated. Occipital nerve stimulation (ONS) is a potentially effective surgical treatment. ⋯ ONS may be an effective surgical treatment for approximately two thirds of patients with medically refractory TACs.

The depth of connective tissue window in the side of a recipient nerve in reverse end-to-side transfers (RETS) remains controversial. ⋯ Creating a perineurial window in the side of recipient nerves provides the best chances of robust donor axonal regeneration across the RETS repair site. This finding aids nerve surgeons by confirming that a deep window should be undertaken when doing a RETS procedure.
