Sphenopalatine neuralgia

Sphenopalatine neuralgia

Sphenopalatine neuralgia, also termed lower half headache, greater superficial neuralgia, and Sluder’s neuralgia, is an uncommon facial pain disorder. Key clinical features include unilateral pain in the face lasting for days and associated with nasal congestion, otalgia, and tinnitus. Unlike trigeminal and GPN, sphenopalatine neuralgia is not commonly associated with a trigger zone. Some authors believe that this is not a separate syndrome and may simply be a variation of cluster headache. Treatment options are limited, but sphenopalatine ganglion blocks have been tried with minimal success.
