Eardrum repair is a surgical procedure used to fix a hole or tear in the eardrum (tympanic membrane). It can also be used to repair or replace the three tiny bones behind the eardrum (ossicles). The eardrum is a thin membrane between your outer ear and your middle ear that vibrates when sound waves hit it. An ear infection, surgery, or trauma may cause damage to your eardrum or middle ear bones that must be corrected with surgery.
