Tympanoplasty is the surgical reconstruction of a damaged eardrum to restore hearing or to prevent recurrent middle ear infections. Perforations of the eardrum occur from infection or trauma to the eardrum. At LACENTA in Los Angeles tympanoplasty is usually minimally invasive and performed either through the ear canal or through a small incision behind the ear and can sometimes involve a graft of tissue taken from the fat or connective tissue that surrounds the ear.
