Tympanoplasty

Tympanoplasty is a surgical procedure aimed at reconstructing the eardrum (or tympanic membrane) and/or the small bones of the middle ear. Eardrum perforation may result from chronic infection or, less commonly, from trauma to the eardrum.

Types of Tympanoplasty

Tympanoplasty can be classified into five different types, depending on the specific nature and location of the damage:

• Type I involves repair of the tympanic membrane alone, when the middle ear is normal. This is also known as myringoplasty.
• Type II involves repair of the tympanic membrane and/or middle ear in cases where the malleus is eroded.
• Type III involves removal of the malleus and incus, and the placement of a graft onto the stapes.
• Type IV involves total removal of all three ossicles, and the placement of a graft onto the footplate of the stapes.
• Type V involves the same procedure as Type IV, but the footplate of the stapes is also removed.

Procedure

The procedure is typically performed under general anesthesia. The surgeon will make an incision either behind the ear or inside the ear canal. The eardrum is then lifted away from the ear canal to expose the middle ear. The surgeon will then repair or replace the damaged structures in the middle ear, using either tissue from the patient (autograft) or a synthetic material (allograft).

Risks and Complications

As with any surgical procedure, there are risks associated with tympanoplasty. These may include infection, bleeding, and an adverse reaction to anesthesia. There is also a small risk of hearing loss or facial nerve damage.

Recovery

Recovery from tympanoplasty generally takes several weeks. Patients are typically advised to keep their ear dry and avoid blowing their nose for the first few weeks after surgery. Follow-up appointments will be scheduled to monitor healing and test hearing.
