pterygopalatine neuralgiaA type of cephalic neuralgia caused by irritation of branches of the pterygopalatine nerve due to pressure or infection.
Homolateral, deep pain or sensation of pressure localised paranasally or periorbitally, radiating towards the forehead or back of the skull.
Septal deformity, usually a spur; less commonly, a neoplasm, foreign body or infection that extends into the posterior part of the inferior turbinate.
Immediate relief of symptoms with anaesthesia of the pterygopalatine ganglion (e.g., with cocaine).
Septal surgery (e.g., removal of inferior turbinate).
