- Cluster headaches are usually intense,
unilateral, and involve the periorbital area.
- CN V
(Trigeminal) provides sensory and autonomic innervation the face
and eyes, which play roles in headache pathology.
- Cluster headaches can be treated with high flow
oxygen, but a new treatment involves blocking the sphenopalatine
ganglion (SPG) with lidocaine. Because sensory and autonomic
branches of the trigeminal traverse the SPG, lidocaine will
effectively treat a cluster headache.
block the ganglion, intranasal lidocaine may be used, or a Q-tip
soaked in 4% lidocaine can be applied to the most posterior aspect
of the pharynx for 10-15 minutes.
