Due to trauma, the postganglionic parasympathetic fibers of the auriculotemporal nerve supplying the parotid gland are sectioned.
The auriculotemporal nerve arises from the third division of the trigeminal nerve and gives rise to postganglionic parasympathetic fibers travelling from the otic ganglion to the parotid gland.
A handheld remote controller placed against the cheek activates the device and controls the intensity of stimulation, which is thought to work by blocking signals to the postganglionic parasympathetic fibers. Those fibers innervate facial structures and the cerebral and meningeal blood vessels and are implicated in the pain and accompanying autonomic symptoms of a cluster headache attack.
The damage to postganglionic parasympathetic fibers may cause this syndrome.
Postganglionic parasympathetic fibers from pterygopalatine ganglion innervate the lacrimal gland and the mucosal glands of the nose, palate, and pharynx.
Postganglionic parasympathetic fibers then join the maxillary nerve to innervate the lacrimal gland and small salivary glands in the nose and palate.
* Frey's syndrome is generally believed to be caused by an aberration in the regrowth of the postganglionic parasympathetic fibers that normally supply the parotid gland.
