Ossiculoplasty in Patients with Chronic Otitis Media
Etsuo Yamamoto
(Kobe City General Hospital)
Classification and nomenclature of the reconstructive method of the middle ear sound-conducting system proposed by the Otological Society of Japan were outlined.
Ossiculoplasty and postoperative hearing results in our clinic were presented. Autogenous materials, such as ossicles, cortical bone chips and bone paste, were recommended as columella materials. More stabilized columella and better postoperative hearing results were obtained when the columella was interposed between the malleus (if present) and the stapes. In cases of total incudostapedial disruption, bone chips and paste was placed on the defective area between the long process of the incus and the head of the stapes. This new method achieved remarkable postoperative improvement of hearing.
Key words : ossiculoplasty, autogenous ossicle, cortical bone chips and paste, stabilization of columella, interposition of columella
