Type IV tympanoplasty is used for ossicular destruction, which includes all or part of the stapes arch. It involves placing a graft onto or around a mobile stapes footplate.
An incision is made into the ear canal and the remaining eardrum is elevated away from the bony ear canal, and lifted forward. The surgeon uses an operating microscope to enlarge the view of the ear structures.
Type II tympanoplasty is a surgical procedure to repair a perforated eardrum and reconstruct the middle ear structures. It involves making an incision behind the ear to access the middle ear, removing any diseased tissue, and then grafting a piece of tissue (often taken from the temporalis muscle) onto the perforation to close it. The aim is to restore hearing and prevent recurrent ear infections.
