The above article published in the latest issue of "European Journal of Neuroscience, discusses issues on hearing loss and possible involvement of trigeminal nerve?

Abstract:
Hearing loss due to VIII nerve damage or loss of synaptic connectivity of VIII nerve in the cochlear nucleus is a common degenerative changes observed in models of noise damage, similar degeneration of terminals also reported in cases of hearing loss in humans. However, the above article discusses the possiblity of the involement of "Trigeminal Nerve" as a compensatory response to the loss of VIII nerve connections following noise induced hearing loss in animal models. How much of this compensatory response is due to hearing loss or changes in VIII nerve connectivity is not clear, however, it is interesting to note how the neighbouring cranial nerve respond.

The authors observe the following changes in responses to trigeminal stimulation: The guinea pigs with noise-induced hearing loss had significantly lower thresholds, shorter latencies and durations, and increased amplitudes of response to trigeminal stimulation than normal animals. Noise-damaged animals also showed a greater proportion of inhibitory and a smaller proportion of excitatory responses compared with normal. Authors also argue that there is increased inhibitory responses and increased activity of somatosensory response, prompting them to conclude a role of somatosensory inputs in noise induced hearing loss? is yet to be clarified by extensive studies!.

'Ringing In The Ears' May Be Caused By Overactive Nerves, Acupuncture May Help, Study Suggests
ScienceDaily (Jan. 10, 2008) — Do your ears ring after a loud concert? Nerves that sense touch in your face and neck may be behind the racket in your brain, University of Michigan researchers say.
