Anthony examined the prevalence of CH among patients with primary headache, and the effects of local corticosteroids into the region of the GON and
lesser occipital nerve (13).
Then Guyuron details the surgical treatment of the different sites of migraine headaches: frontal, temporal, rhinogenic, occipital, aurico-temporal,

(1), six nerves are identified by landmarks on each side of the cranium (supratrochlear, supraorbital, zygomaticotemporal, auriculotemporal,
lesser occipital and greater occipital nerves), and they are subsequently infiltrated with a local anaesthetic dose ranging from 2 to 5 mL.
The
lesser occipital, great auricular, transverse cervical and supraclavicular nerves were preserved.
There are multiple causes of CeH, including the [C.sub.2]-[C.sub.3] and [C.sub.3]-[C.sub.4] z-joints, A-A joint, [C.sub.2]-[C.sub.3] intervertebral disk, A-O joint, and the greater or
lesser occipital nerve [1].
The cervical plexus consists of the ventral primary divisions of the first four cervical spinal nerves and gives rise to (1) the muscular branches, including the phrenic nerve and nervus descendens cervicalis, as well as (2) the sensory branches, including the
lesser occipital, transverse cutaneous, supraclavicular, and great auricular nerves.
(2) Previous evidence indicates that occipital neuralgia affects the greater occipital nerve in 90% of cases,
lesser occipital nerve in 10% of cases, and both occipital nerves in 9% of cases.
Sudden unconsciousness during a
lesser occipital nerve block in a patient with the occipital bone defect.
Often though, we see it manifested after physical insult to the greater or
lesser occipital nerve pathways i.e.
BT-B was administered intradermally, over the site of the greater and
lesser occipital nerves on the side of predominant migraine headaches.
the
lesser occipital (anterior ramus of C2) supplies the skin behind the ear.
