Event Description

It is reported during a tympanomastoidectomy with ossiculoplasty procedure using a gyrus titanium porp prosthesis (for the ossiculoplasty part of the surgery), the physician mistakenly implanted the temporary sizer prosthesis and not the permanent prosthesis.The metal box with different size prostheses was given to the physician.The physician picked a 2 mm prosthesis and proceeded to implant in the middle ear and completed the surgery.The physician reports not being informed during the case by either the circulator or the scrub nurse that what he had used was a temporary prosthesis.This was not discovered until the procedure was concluded and the patient was already in the recovery room.Three days later, the patient was taken back to surgery to remove the temporary implant and install the permanent implant.No additional consequences to the patient have been reported.The physician reported having used a similar prosthesis recently.However, have not used this item regularly to be aware that it comes with sizers at 2mm, 3mm, etc., and then an individual box of the appropriate size implant is opened to be used.
