Autologous fitted incus versus PlastiporeTM PORP in ossicular cgain reconstruction

Abstract

AbstractHearing results and causes of failure with three types of ossicular reconstruction techniques over an infact stapes, during second-stage intact canal wall tympanoplasty, are reporte herein.The three types of reconstruction are: fitted autologous incuc (38 cases): PlastiporeTM PORP with cartilage (41 cases): PlastiporeTM PORP without cartilage (32 cases).A residual air-bone gap within 15 dB. was found in 63.2 per cent of fitted incudes, in 41.5 per cent of PORPs with cartilage, and in only 37 per cent of PORPs without cartilage.Eighty-four per cent fitted incudes, 63 per cent PORPs with cartilage and 44 per cent PORPs without cartilage yielded a residual air-bone gap within 25 dB.Extrusion has been the main cause of failure among PlastiporeTM prostheses.
