What are healed TM perforations with incomplete fibrous layers called?

• A. Monomers
• B. Myringitis
• C. Otitis externa
• D. Cerumen impaction

Answer: (A)

Healed tympanic membrane (TM) perforations that exhibit incomplete fibrous layers are referred to as monomers. This term specifically describes the state of the tympanic membrane after a perforation has healed but without the full normal structure restored. Unlike a fully healed tympanic membrane, a monomer has less fibrous tissue, which can affect the membrane's acoustic properties and overall function. In contrast to monomers, myringitis typically refers to an inflammation of the tympanic membrane and does not specifically denote a healed perforation. Otitis externa is an infection of the outer ear canal and is not related to the status of the tympanic membrane. Cerumen impaction involves an obstruction in the ear canal caused by earwax and is unrelated to perforations of the TM.
