The tympanic nerve (nerve of Jacobson) is a branch of the glossopharyngeal nerve found near the ear.

Path

It arises from the petrous ganglion, and ascends to the tympanic cavity through a small canal, the fossula petrosa/tympanic canaliculus, on the under surface of the petrous portion of the temporal bone on the ridge which separates the carotid canal from the jugular fossa.

In the tympanic cavity it divides into branches which form the tympanic plexus and are contained in grooves upon the surface of the promontory.

Jacobson's nerve contains both sensory and secretory fibers.

Sensory fibers supply the middle ear.
Parasympathetic secretory fibers continue as the Lesser Petrosal nerve and provide secretomotor innervation to the parotid gland. The secretory fibers enter the otic ganglion.
Sympathetic fibers (for the large deep petrosal nerve) through communication with the carotid plexus

The postganglionic parasympathetic fibers are then distributed via the auriculotemporal nerve (branch of the trigeminal nerve) to the parotid gland.

Clinical significance

This nerve may be involved by paraganglioma, in this location referred to as glomus jugulare or glomus tympanicum tumours.

Per-endoscopic trans-tympanic traction for the management of feline aural inflammatory polyps: a case review of 37 cats.

Greci V, Vernia E, Mortellaro CM.Author information 1Gregorio VII Veterinary Hospital, Rome, Italy.AbstractFeline aural inflammatory polyps are benign growths originating from the tympanic cavity or the Eustachian tube. They usually occur in young cats, which present either signs of otitis externa and otitis media, or respiratory signs, depending on the direction of the polyp growth. Neurological signs are also reported. Simple traction and ventral bulla osteotomy (VBO) are the most common techniques used for treating this condition in cats; corticosteroids are recommended to reduce risk of recurrence given the inflammatory nature of the disease. The most common complications after treatment are Horner's syndrome, polyp recurrence and facial nerve paralysis. The aim of this report is to describe the per-endoscopic trans-tympanic traction (PTT) technique for treating feline aural inflammatory polyps and to report the short- and long-term outcomes of this procedure. PTT allowed resolution of the aural inflammatory polyps in 94% of cats during a mean long-term outcome of 19 months. Three cats (8%) developed Horner's syndrome immediately after the PTT procedure, which resolved within a few weeks, and five cats had polyp recurrence (13.5%). Only two cats had a poor outcome and were diagnosed with chronic otitis media at 22 months, and chronic otitis media and polyp recurrence at 46 months after the PTT procedure, respectively. PTT was shown to be an effective technique for treating aural inflammatory polyps and registered fewer neurological complications (8%) than VBO (57-81%) or simple traction (43%), and a recurrence percentage (13.5%) similar to VBO (0-33%) and much lower than traction alone (57%).
