Tympanoplasty - Eardrum Repair Surgery
What is tympanoplasty?
Tympanoplasty is a surgical procedure to repair a perforated (hole in the) eardrum. The eardrum - a delicate membrane just 0.1 mm thick, separating the outer ear canal from the middle ear - can be perforated by chronic middle ear infection, trauma (a slap on the ear, cotton bud injury, or blast injury), barotrauma from rapid pressure changes, or as a complication of ear surgery. Small acute perforations sometimes seal spontaneously within 6-8 weeks. Large or chronic perforations, however, do not heal on their own and require surgical repair.
Why is repair needed?
An unrepaired eardrum perforation causes recurrent middle ear infections with discharge (since water and bacteria can enter the middle ear directly), hearing loss (because a complete, intact eardrum is essential for vibration and sound transmission), and restriction from water activities. Left unaddressed, chronic middle ear infection through a perforation can progress to cholesteatoma - a destructive condition with serious complications.
What happens during surgery?
Under general anaesthesia and operating microscope magnification, the surgeon freshens the edges of the perforation to stimulate healing and places a graft to bridge the gap. The graft is most commonly taken from the temporalis fascia - a thin, tough membrane just above and in front of the ear - or from the cartilage and perichondrium of the tragus (the small cartilage at the entrance of the ear canal). The approach is either entirely through the ear canal (transcanal, for smaller perforations) or through a small incision behind the ear (postauricular, for larger perforations or when the ear canal is narrow).
Types of tympanoplasty
- Type I (Myringoplasty): Repair of the eardrum perforation alone, with normal middle ear bones
- Type II-V: Eardrum repair combined with reconstruction of damaged or eroded hearing bones (ossiculoplasty)
Recovery
Hospital stay: 1 day. Ear packing is removed at 1-2 weeks. The ear must be kept completely dry for 4-6 weeks. Full hearing improvement is assessed with audiometry at 6-8 weeks post-surgery. Most patients return to office work within 5-7 days.
