Where is the nervus intermedius?
The intermediate nerve, nervus intermedius, nerve of Wrisberg or Glossopalatine nerve, is the part of the facial nerve (cranial nerve VII) located between the motor component of the facial nerve and the vestibulocochlear nerve (cranial nerve VIII). It contains the sensory and parasympathetic fibers of the facial nerve.
What is nervus intermedius neuralgia?
Nervus intermedius neuralgia is an extremely uncommon pain syndrome in which the pain is very similar to that of trigeminal neuralgia but in the distribution of n. intermedius. Generally it is presumed that its etiology is the cross compression of the nerve at its central-peripheral myelin junction.

It enters the middle ear cavity through the inferior tympanic canaliculus, runs in a canal on the cochlear promontory and provides the main sensory innervation to the mucosa of the mesotympanum and Eustachian tube.

What happens if accessory nerve is damaged?
The spinal accessory nerve originates in the brain and enables motion in the trapezius and sternomastoid muscles in the neck.
