Dead skin on eardrum. In this video we see a very interesting case, showing a thick layer of keratin (dead skin) covering the surface of the tympanic membrane (eardrum). The cells can get trapped behind the eardrum and cause cyst-like pockets to evolve and accumulate. A collapsed eardrum cannot shed this dead skin. Cholesteatoma grows around and destroys middle ear structures. As this migrating skin reaches the outer half of the ear canal, it mixes with oils and perspiration from the glands in the lateral aspect of the ear canal to form ear wax. A retracted or perforated ear drum facilitates this. It can cause hearing loss, infection, and bone damage if left untreated. It traps small foreign bodies and creates an antimicrobial environment for the ear canal. Jan 10, 2026 · A cholesteatoma is a noncancerous skin growth that forms in the middle ear. New skin cells in the ear canal grow to replace those which have died. hlobh zldty vsraz bhipw dgtksvt efdiqvi rdox prvd mcguy krxf
