What is the difference between ak, keratosis obturans and cholesteatoma?
A doctor has provided 1 answer
Good questions: Keratosis obturans is a hyperkeratotic growth of superficial skin of the bony ear canal skin and as such is seborrheic dermatitis of the bony ear canal skin. Cholesteatoma, primary or secondary is a growth of skin in the middle ear arising from either a migration of skin from a perforation or congenital. Cholesteatoma is potentially dangerous and can destroy bone and result in serious disease.
