The tympanic membrane is the eardrum. The membrane separates the external ear from the middle ear and serves to amplify sound. A tympanic membrane perforation is a hole in the eardrum.
There are many possible causes of eardrum perforation. These include:
Tympanic membrane perforation can be suspected with a history of ear trauma, ear tubes, frequent ear drainage or hearing loss. Hearing testing with testing of middle ear pressure (tympanogram) can raise the suspicion for a tympanic membrane perforation. Diagnosis requires an exam of the external and middle ear (otoscopy) which can be done with an otoscope or microscope.
Many tympanic membrane perforations heal without any intervention and it is important to know that not all perforations need to be repaired. Dry ear precautions and antibiotic eardrops can be used to treat concurrent infection as the eardrum perforation heals.
Perforations that persist despite observation can be repaired in several different methods. The eardrum can be patched with a small graft (called a myringoplasty) or in some cases, a formal tympanoplasty or eardrum reconstruction is needed.
While many of these perforations can be repaired through the ear canal without any incisions around the ear, some require harvest of graft material from behind the ear and/or an approach from behind the ear to be able to adequately reconstruct the eardrum.
