Tympanoplasty with mastoidectomy (including canalplasty, middle ear surgery, tympanic membrane repair); radical or complete, without ossicular chain reconstruction

A tympanoplasty with mastoidectomy is a surgical procedure that combines the repair of the tympanic membrane (eardrum) with the removal of infected or diseased mastoid bone. This operation is indicated for patients suffering from chronic ear infections, cholesteatoma, or other conditions that compromise the integrity of the middle ear and surrounding structures. The procedure may involve additional techniques such as canalplasty, which is the widening of the ear canal, and middle ear surgery to address any abnormalities or damage within the ear. The classification of tympanoplasties is based on the extent of the repair needed; in this case, the procedure is categorized as a radical or complete mastoidectomy, which entails a significant removal of mastoid bone to create a single cavity that encompasses both the mastoid and the ear canal. The surgical approach typically involves an incision behind the ear to access the mastoid bone, allowing for thorough inspection and removal of any infected tissue, debris, and purulent matter. The goal of this procedure is to restore hearing, eliminate infection, and prevent future complications while ensuring the structural integrity of the ear is maintained.
