User:Siricruz/Sluder's syndrome

Sluder's syndrome, also known as Sluder's neuralgia, anterior ethmoid neuralgia, pterygopalatine ganglion neuralgia, or sphenopalatine ganglion neuralgia, is an unusually rare form of contact point headache or neuralgia characterized by vague pain of the nose and orbit of the eye, sometimes with extension to the rest of face and shoulders and neck. Generally not regarded as a disease a sui generis it has been variously subsumed under the term "cluster headache", though cluster headache is a generic term for a host of conditions with no known cause, and Sluder's syndrome is specifically defined as being caused by compression of the maxillary division of the 5th cranial nerve by the nasal concha or concha bullosa within the nasal cavity.
