Abstract:
China Journal Full-text Database (CJFD) was undertaken to identify relevant articles. This article aims to classify data on ossicular replacement prosthesis (ORP) and to analyze the application of different kinds of ORP to auditory rehabilitation. Studies demonstrated that different ORP had different advantage or disadvantage. Autologous cartilage is convenient to obtain and difficult to absorb such as antilobium cartilage, nasal septum cartilage and so on. But degeneration and absorption are detected in a long-term. Homograft tooth with good histocompatibility, tooth sound conduction, weak rejection and high stability is easy to collect, to store for a long time, and to apply in clinic, as well as without organic matter after disposing. However, this kind of tooth is easy to move and cannot be used by most physicians. Titanium ORP possesses good biocompatibility and histocompatibility, avirulence, corrosion resistant properties, light mass, and is hard to dislocate, can firmly connect to the stirrup bone, resulting in a postoperative significant outcome. Bioceramic ORP is widely used in ear surgery, because it has inorganic salt component, good biocompatibility, and low dislocation rate. With deep studies on biomaterials and discovery of new materials, many scholars have designed a compound auditory ossicle to combine the predominance of various materials and to avoid their shortcomings.
