Sphenopalatine ganglion block: a new treatment for burning mouth syndrome? - a case report.

Burning mouth syndrome is a poorly understood entity for which current treatment modalities fail to provide effective relieve. Branches of the maxillary and mandibular nerves are responsible for the innervation of the affected area. These are also the nerves involved in trigeminal neuralgia, an entity where sphenopalatine block has proved to be effective. We present a case of a patient with burning mouth syndrome in whom a bilateral sphenopalatine ganglion block was successfully performed for pain treatment. It is an easy and safe technique that can be a valuable treatment option for these patients, although more studies are needed.
