Are stapes prosthesis MRI safe?
The author concludes that all patients with stapes prostheses can safely undergo MRI scans, unless the patient received a McGee piston from 1987-1989 or if the patient received a stapes prosthesis from 1987-1989 and it is not known with certainty which implant was used.
Can I have an MRI if I’ve had a Stapedectomy?
It is safe to have MRI scan after a stapedectomy operation. Patients may fly in a plane three weeks after surgery. Otosclerosis is a disorder in which abnormal bone forms around the stapes — a tiny bone within your inner ear.
What implants are not safe for MRI?
Some implants are not compatible with MRI scanners….Other implants that should be brought to the technologist’s attention are:
- Artificial heart valves.
- Implanted drug infusion ports or pumps.
- Artificial limbs or metallic joint prostheses.
- Metal pins, screws, plates, stents, or surgical staples.
- Some IUDs.
What are stapes implants made of?
The prosthesis has been constructed with such material as steel, platinum, gold, Teflon, titanium and alloys [9–12]. Teflon piston is the most commonly employed prosthesis in stapes surgery [13].
What is a stapes implant?
Stapes prosthesis (plural: stapes prostheses) are used in the stapedectomy surgery procedure which aims to improve conductive hearing loss due to oval window closure secondary to otosclerosis or post inflammatory conditions.
What material is used in a stapedectomy?
The materials evolved from Teflon, metal, to plastic, and most recently to gold and titanium. While initially the diameter of the pistons used was 0.8 and 0.6 mm, from the 1970s onwards, it has been becoming even smaller in order to ease the procedure and reduce the risk of inner ear damage.
What metal is used in a stapedectomy?
Teflon piston is the most commonly employed prosthesis in stapes surgery. Titanium pistons are relatively the new development in the evolution of stapes prosthesis.
Can you have an MRI with metal implants?
In most cases, an MRI exam is safe for patients with metal implants, except for a few types. People with the following implants may not be scanned and should not enter the MRI scanning area without first being evaluated for safety: some cochlear (ear) implants. some types of clips used for brain aneurysms.
