We compared the results of 33 patients receiving autogenous bone graft (a part of the ossicle or cortical bone) and 12 receiving Plastipore (PORP, TORP) for ossicular chain reconstruction in tympanoplasty. All cases were followed up for at least 6 months after operation with hearing examination.<BR>In the autogenous bone graft group, the hearing results were good, and there was no extrusion. In the Plastipore group, though the hearing results were similar to those in the autogenous bone graft group, extrusion was present in 20% of the cases in which the bone chip was placed between the Plastipore prosthesis and the tympanic membrane (or temporal fascia). However, all of the exhibiting extrusion had poor eustachian tube function. Plastipore should be used for ossicular reconstruction in patients with good eustachian tube function.
