During this initial or revision procedure, the provider reconstructs the tympanic membrane, or eardrum, to fix a perforation and reconstructs the ossicular chain to improve conductive hearing. With the ossicular chain reconstruction, the provider places a synthetic prosthesis. This might involve reconstruction of the ear canal, an incision into the tympanic attic and or other surgeries of the middle ear. This procedure does not include removal of the mastoid cavity.
