![]() ![]() Patients were free of pain after the second procedure at a mean of 40.3 months of follow-up. 464, 2781292, IMP FELT TEFLON 6 X 6 IN STER 007837, 177.33, C1768, Y. There was no statistically significant difference in either hearing gain or air-bone gap overclosure between the two prostheses. Stapedotomy was performed on the footplate of the stapes and a 0.4 mm Teflon platinum piston (Richard Co, Memphis, Tenn ) with a length of. The Teflon granuloma was completely removed, and a new Teflon felt was used for re-decompression. List Rec 3336 Object Description Richards piston stapes prosthesis (platinum, fluoroplastic) otologic implant Richards Medical Co. Measurements of implant locations within the dishes were taken before and after MRI magnet exposure. Following primary stapes surgery, the air-bone gap overclosure was 4.4 dB with the Teflon-wire piston and 5.2 dB with the stainless-steel bucket prosthesis. then placed into MRI scanners at 1.5, 3.0, 4.7, and 9.4 T (4,5Y10). Dishes, Evaporating and Other Metal Vessels (for Platinum See Class 175-71). Teflon platin piston richard mri portable#Patients who received the stainless-steel bucket prosthesis experienced a mean hearing gain of 20.7 and 20.3 dB, respectively. Grinders, Cylinder Hone and Valve Seat Portable Boring Machines Hones. The mean hearing gain for the patients who received the Teflon-wire piston was 23.3 dB after primary stapes surgery and 20.5 dB after revision surgery. We retrospectively reviewed the outcomes of 82 surgeries that had been performed by the primary author 41 of these patients had received a Fisch Teflon-wire piston, and 41 had received a Bailey-modified Robinson stainless-steel bucket prosthesis. 6203, University of Colorado Hospital, 073000, HB OR-PROSTHESIS TEFLON PISTON. Shellock, PhD # Radiology August 1991ģ Metaffic Implants, Materials, and Devices Tested for Movement/Deflection Forces during Exposure to Static Magnetic Fields (Continued) Metaffic Implant, Movement/ Highest Field Metallic Implant, Movement/ Highest Field Material, or Device Deflection Strength (F) Referewe.The goal of this study was to determine whether postoperative (implantation of a stapes prosthesis) hearing gain and the amount of air-bone gap overclosure are more improved with the Teflon-wire piston or with the stainless-steel bucket prosthesis. 505, University of Colorado Hospital, 002331, HB RADIANT MRI UP EXTREM NOT. ![]()
