Other supporting data includes a consistent loss of cochlear hair cells in patients with otosclerosis; these cells being the chief sensory organs of sound reception. A suggested mechanism for this is the release of hydrolytic enzymes into the inner ear structures by the spongiotic lesions.
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.
The hearing loss and ringing in the ears can become constant over time. [4] The cause of Ménière's disease is unclear, but likely involves both genetic and environmental factors. [1] [3] A number of theories exist for why it occurs, including constrictions in blood vessels, viral infections, and autoimmune reactions. [3]
Hemotympanum refers to the presence of blood in the middle ear, which is the area behind the eardrum. In most cases, the blood is trapped behind the eardrum, so no discharge is visible. Treating hemotympanum depends on the underlying cause.

A seroma contains serous fluid. [1] This is composed of blood plasma that has seeped out of ruptured small blood vessels and the inflammatory fluid produced by injured and dying cells. [citation needed] Seromas are different from hematomas, which contain red blood cells, and abscesses, which contain pus and result from an infection.
The findings suggest that people born in the southern U.S. face a higher risk of developing dementia over time, along with people who are Black and Hispanic—although there are modifiable things ...
The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3] Recovery from a reflex syncope episode happens without specific treatment. [2]
