Atypical facial neuralgia in damages of the sphenopalatine ganglion probably due to vasodilatation of the internal maxillary artery. It is a headache syndrome characterised by neuralgia which is often preceded by infection of nasal sinuses. Occurs most commonly in females after the age of 30 years. The pain is usually unilateral, involving the maxilla, teeth, ear, mastoid, auricular area, the base of the nose, and the area beneath the zygoma, usually in association with itching in the palate, peculiar sense of taste, sneezing, and nasal congestion. Attack lasts minutes, hours, or days. Writers disagree whether this is an autonomous entity.
