[The application of cartilage in middle ear surgery].

Summary The aim of this study is to review the application, techniques and procedures of cartilage in the middle ear surgery. Cartilage offers the advantage of higher mechanical stability in tympanoplasty, which is the most common procedure in the middle ear surgery, thus apply to much complicated situation especially for tubal dysfunction and adhesive processes. There are many variations on the shape, size, thickness and technical matters of the cartilage grafts. The past decades and literature have observed excellent graft take rates and good postoperative hearing outcomes for cartilage tympanoplasty and the reservation of perichondrium seems to show better long-term survival. There have been concerns regarding malacia of cartilage struts, as a result, cartilage struts for ossiculoplasty have not gained popularity except for combined application with synthetic materials. Meanwhile, the benefits of cartilage in the reconstruction of posterior canal wall and attic, mastoid obliteration and adhesive otitis media have been demonstrated in the previously published studies. It is well to be reminded that cartilage could be applied in some unusual cases such as vibrant soundbridge, meningoencephalocele.
