The middle ear is the portion of the ear internal to the eardrum, and external to the oval window of the inner ear. The mammalian middle ear contains three ossicles, which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear. The hollow space of the middle ear is also known as the tympanic cavity and is surrounded by the tympani bone.
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea, dedicated to hearing; converting sound pressure patterns from the outer ear into electrochemical impulses which are passed on to the brain via the auditory nerve.
Pathogenesis of the Inner Ear. Vertigo: Malfunctions of the Vestibular System. Hearing impairments may have various reasons. The first stems from a damage to the middle ear, which prevents the proper transmission of sound. The relevant stimulus, the sound, does not or not completely reach the hearing organ-while the latter is in itself functional.
When the inner ear suffers nerve damage, certain symptoms may be present. Patients may experience inner ear inflammation, dizziness, hearing reduction or loss, or a loss of sound clarity. An additional symptom seems to be a paradox. It is called ‘recruitment’ and involves some hearing loss with sensitivity to loud noises. Causes and Complications. Inner ear nerve damage caused by a viral infection can be permanent.
Loud sound overwhelms the ear's delicate mechanisms, and can damage the tiny hair cells in the inner ear that pick up sound waves, or the nerves that relay information from those hair cells to the brain. The brain, so the theory goes, then over-compensates for the missing input, in the same way that amputees experience phantom sensations from a lost limb. Tinnitus has been called "phantom auditory perception. But many sufferers simply learn to deal with the condition on their own terms. The older I get and the more I get used to it, the less it bothers me," says Matthew Barnes, AKA Forest Swords, of his tinnitus.

Ear Damage Metal, Southampton.
In inner ear barotrauma in guinea pigs, damage to the organ of Corti was observed in various parts of the cochlear turns in varying severity. Some animals showed rupture of the round window membrane and/or reduction of endocochlear potential following the barotrauma but the rupture healed and EP recovered spontaneously within one week. We consider that irreversible hearing loss in patients with inner ear barotrauma depends on the extent of damage to the organ of Corti. Download full-text PDF. Source. In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts:. The cochlea, dedicated to hearing; converting sound pressure patterns from the outer ear into electrochemical impulses which are passed on to the brain via the auditory nerve. The inner ear is found in all vertebrates, with substantial variations in form and function. The inner ear is innervated by the eighth cranial nerve in all vertebrates.
