Whilst hearing loss is a common symptom in many diseases of the ear, for example in otosclerosis (abnormal bone growth in the ear), [3] the white, chalky patches on the tympanic membrane are fairly characteristic of tympanosclerosis. Cholesteatoma is similar in appearance but the whiteness is behind the tympanic membrane, rather than inside.
Keratosis obturans is a relatively uncommon ear disease, where a dense plug of keratin, formed by abnormal accumulation of desquamated skin in sheet-like layers , forms in the bony (deeper) part of the external auditory canal. [1]
In the absence of a pathology, a loud sound (generally greater than 70 dB above threshold) causes the stapedius muscle to contract, reducing the admittance of the middle ear and softening the perceived loudness of the sound. If the mobility of the stapes is reduced due to otosclerosis, then stapedius muscle contraction does not significantly ...

Ménière's disease usually starts confined to one ear; it extends to both ears in about 30% of cases. [5] People may start out with only one symptom, but in Ménière's disease all three appear with time. [5] Hearing loss usually fluctuates in the beginning stages and becomes more permanent in later stages.
Endolymphatic hydrops is a disorder of the inner ear. It consists of an excessive build-up of the endolymph fluid, which fills the hearing and balance structures of the inner ear. Endolymph fluid, which is partly regulated by the endolymph sac, flows through the inner ear and is critical to the function of all sensory cells in the inner ear.
There can be damage either to the ear, whether the external or middle ear, to the cochlea, or to the brain centres that process the aural information conveyed by the ears. Damage to the middle ear may include fracture and discontinuity of the ossicular chain. Damage to the inner ear (cochlea) may be caused by temporal bone fracture. People who ...
