Abstract
The goals myringoplasty and tympanoplasty are to achieve a dry, self-cleansing ear while preserving or restoring hearing. Myringoplasty refers to grafting of the tympanic membrane without inspection of the ossicular chain. Tympanoplasty entails grafting of the tympanic membrane with inspection of ossicular chain with/without reconstruction of the middle ear hearing mechanism. Ossiculoplasty is reconstruction of the hearing mechanism using either an autologous graft or prosthesis. Meatoplasty involves enlargement of the lateral cartilaginous portion of the external auditory canal. A narrow entrance to the ear canal within the cartilaginous portion of the canal prevents proper ventilation and self-cleaning of the ear canal and may compromise hearing aid fitting. Canalplasty is partial or total widening of the bony portion of the external ear canal. In order to visualise the tympanic annulus, particularly in anterior or subtotal perforations, canalplasty is essential and may be an integral part of myringoplasty or tympanoplasty.
