[Tolerance of Plasti-Pore prostheses in ear surgery].

The authors describe the tolerance of Plasti-Pore prosthetic ossicles in reconstructive surgery of the middle ear. Tolerance is excellent where cartilage is interposed between the prosthesis and the tympanic graft (0% failure). Without such insertion of cartilage, the authors note a protrusion by the prosthesis with tympanic perforation in 19.3% of cases, except in those where the tympanic graft is a homograft (0% failure). In the case of a tympanic graft using temporal aponeurosis it is therefore advisable to interpose a fragment of cartilage. This insertion of cartilage does not appear necessary in the case of a tympanic homograft.
