[Practical pointers on the use of Plastipore middle ear implants (TORP, PORP)].

"Plastipore" prostheses (TORP, PORP) in the middle ear have established themselves in recent years for the restoration of optimal transformation of air pressure in partial or total loss of the ossicular chain, provided that certain conditions are observed. A good protector between the tympanic membrane or the tympanic membrane graft, and a prosthetic screen is essential. For this we use a transplant composed of perichondrium and cartilage from the tragal cartilage cut in a certain manner, which also functions ideally as a tympanic membrane graft. The technique and the results are described.
