Tympanoplasty without mastoidectomy (including canalplasty, atticotomy and/or middle ear surgery), initial or revision; without ossicular chain reconstruction

A tympanoplasty without mastoidectomy is a surgical procedure aimed at repairing the tympanic membrane (eardrum) and possibly addressing issues within the middle ear, without the need for mastoidectomy, which involves the removal of the mastoid bone. This procedure can be performed as an initial surgery or as a revision of a previous tympanoplasty. It may include additional techniques such as canalplasty, which is the widening of the ear canal, and atticotomy, which involves accessing the attic of the middle ear. The primary focus of this procedure is to repair the tympanic membrane without reconstructing the ossicular chain, which consists of the small bones in the middle ear that are crucial for hearing. The surgery can be approached through the ear canal or via a post-auricular incision, depending on the specific circumstances of the patient's condition. If the external auditory canal is narrowed due to recurrent infections, a canalplasty is performed to enhance access. During the procedure, the surgeon inspects the tympanic membrane and middle ear structures, removes any scar tissue, and prepares the site for grafting. The grafting process involves harvesting tissue, which may include skin, fat, tendon, or fascia, to cover the perforation in the tympanic membrane. The procedure is designed to restore the integrity of the eardrum and improve hearing, while also addressing any underlying issues in the middle ear without the complexity of ossicular chain reconstruction.
