[Pterygopalatine ganglion syndrome].

An examination of 75 patients with the syndrome of pterygopalatine ganglian established that in out-patient practice such disorders are frequently incorrectly diagnosed. As a rule the disorder is seen at young and middle age after general infections and local inflammatory processes. Acute and subacute development is expressed more frequently in a neuralogical form of the disease while the chronic development corresponds more commonly to a neurotic affection of the ganglion. Clinical criteria in the diagnosis of the pterygopalatine ganglion syndrome are pain attacks with a certain localization and its irraidiation, accompanied by vegetative vascular and secretory changes of a parasympathical character. An important sign in the differential diagnosis is an arrest of the attack by a cocainization of the mucous in certain parts of the middle nasal passage.
