Ta. Dorsay et al., CINE MRI IN THE EVALUATION OF THE PROPLAST-TEFLON TMJ INTERPOSITIONALIMPLANT, Journal of computer assisted tomography, 19(5), 1995, pp. 800-803
Proplast-Teflon (Vitek Inc., Houston, TX, U.S.A.) interpositional impl
ants (PTIPIs) have been removed from the market due to complications t
hat include severe bony destruction of both condyle and fossa as a res
ult of exuberant foreign body giant cell reaction. As per Food and Dru
g Administration recommendations, the radiologist will often be called
to evaluate the status of these implants in the large population that
received them. We present a case of bilateral PTIPIs with nonreducing
anterior displacement of the meniscal prosthesis made more apparent b
y cine MRI. Extensive granulomatous reaction in the temporal bone exhi
bited mobility with cine.
