Rarely, Mycobacterium species can also cause the infection. Some mastoiditis is caused by cholesteatoma, which is a sac of keratinizing squamous epithelium in the middle ear that usually results from repeated middle-ear infections. If left untreated, the cholesteatoma can erode into the mastoid process, producing mastoiditis, as well as other ...

Cholesteatoma is similar in appearance but the whiteness is behind the tympanic membrane, rather than inside.

[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.
This hypothesis is pretty radical, and goes against what most experts in the field believe. But understanding the root cause (or causes) can help prevent, diagnose, and treat Alzheimer's in the ...
