Cartilage Perichondrium Ring Graft versus Cartilage Perichondium Crescent Shaped Graft in Type One Tympanoplasty

Abstract

To improve the functional and audiological results of Tympanoplasty, Ring graft was created but with some difficulty during insertion the graft medial to the handle of malleous. As a trial to overcome this disadvantage, we created a novel graft: cartilage-perichondrium-composite crescent shaped graft, which is put later all to the handle of malleous below the annulus (underlay). It has the same functional and audiological results of the ring graft but with a shorter time, making it superior in tympanoplasty type one
