This document provides an overview of ossicular prosthesis for ossicular chain reconstruction. It discusses the etiology of ossicular disruption, classifications of ossicular discontinuity, preoperative assessment, contraindications, available prosthesis materials including autogenous incus, cortical bone, cartilage, and biocompatible materials. It describes partial ossicular replacement prostheses and total ossicular replacement prostheses, along with options for each. Key factors for success include the status of the ossicular chain and middle ear mucosa. The goal of reconstruction is to improve hearing to within 15 dB of the normal ear.
