Tympanic membrane retraction used to manage tympanic membrane retraction, with the aims of preventing or relieving hearing loss and cholesteatoma formation. As retraction pockets may remain stable or resolve spontaneously, it may be appropriate to observe them for a period of time before considering any active treatment. The Valsalva maneuver increases middle ear pressure and can push a retracted eardrum out of the middle ear if is not adherent to middle ear structures. Hearing may improve as a result, however it can be a painful maneuver. The benefits are typically only temporary. Middle ear pressure can also be increased by Politzerization and with
Tympanic nerve then distributed via the auriculotemporal nerve (branch of the trigeminal nerve) to the parotid gland. This nerve may be involved by paraganglioma, in this location referred to as glomus jugulare or glomus tympanicum tumours. Tympanic nerve The tympanic nerve (nerve of Jacobson) is a branch of the glossopharyngeal nerve found near the ear. It arises from the petrous ganglion, and ascends to the tympanic cavity through a small canal, the inferior 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
