title: [The comparative audiometric statistical study of the results obtained with plastipore or with autologous material in tympanoplasty with mastoidectomy].
abstract: Two hundred forty-three patients underwent from 1984 to 1989 open (OT) or closed (CT) tympanoplasty and mastoidectomy, generally for cholesteatoma or non-cholesteatomatous chronic suppurant otitis media with some type of destruction of the ossicular chain. The results of the audiometric studies of 8 groups who underwent the same surgical technique using plastipore PORP or TORP, or autologous ossicle or cortical mastoid bone, were compared statistically after 2 years of evolution. Except for one of them, none of groups studied presented statistically significant differences, but the existence of more extrusions with the plastipore caused us to stop using it. The material of choice in our service is the autologous ossicle.
