Abstract
TEM [transmission electron microscopy] and SEM [scanning electron microscopy] were used to evaluate the fate of 11 Plasti-pore prostheses left in the human middle ear for periods varying from 7-34 mo. It was evident that Plasti-pore is a relatively inert material based on its clinical performance, absence of gross fibrous tissue reaction from the middle ear, and the unchanged physical characteristics of the prosthesis. Micro-disintegration of the TORP [total ossicular replacement prosthesis] and PORP [partial ossicular replacement prosthesis] was suggested by the consistent foreign body reaction invading their structure, and the presence of particulate-like matter inside the giant cells. Micro-disintegration did not affect the physical characteristics of the prosthesis and seem to have little bearing on their clinical performance. The question of the long-term performance of Plasti-pore remains to be answered.
