Without leading to potential adversities for patients middle ear implant Application in case of stapes may: Literature review, and adverse outcomes after MRI in patients with otosclerosis or congenital abnormalities the need for removal! He reviewed various in vitro and in vivo animal experiments that have all demonstrated the safety of stainless steel (with the exception of certain McGee pistons) and titanium prostheses up to 9.4T. Methods: A survey regarding implant usage, MRI procedures, and adverse outcomes after MRI in patients previously undergoing stapes procedures. Grace . Hypothesis: A 3-T magnetic resonance field may cause motion or displacement of middle ear implants not seen in studies with 1.5-T magnets. doi: 10.1097/01.mao.0000235311.80066.df. A total of 28 lots of the McGee piston (Richards Company, Memphis, Tennessee) made with grade 400 stainless steel were recalled. Tertiary care, University Medical Center. Stapes reconstruction is also performed for discontinuity or fracture resulting from prior basilar skull fracture, binding cicatricial adhesions, or tympanosclerosis. Objective: Although stainless steel stapes prostheses have generally been considered magnetic resonance imaging safe, there is concern that this may change with the development of more powerful imaging systems. Surveys with the otologic surgeons demonstrated that there has only been one case of recognized prosthesis displacement during MRI, and this case involved the aforementioned McGee piston. Neuro/Cerebrum2. The LWS, reported by McGee in 1981 [5], is characterized by a prosthesis loosely attached to the vibrating incus, thus leading to an unexpectedly incomplete ABG closure, to distortion of sound and to poor speech discrimination.

The SMart 360 Piston has a shape memory property that allows the piston loop to hug the incus circumferentially. In addition, 2 physician's surveys revealed no other cases of symptoms or damage to the ears of patients with stapes prostheses that had been exposed to an MRI scanner.
