OBJECTIVE
To present a technique used to assess metallic otologic prostheses for magnetic susceptibility during surgery.
STUDY DESIGN
Description of a surgical technique.
METHODS
A sterile handheld pacemaker magnet is used to evaluate the prosthesis prior to implantation. The magnet is placed over the prosthesis and the prosthesis is placed directly on the magnet. Any evidence of magnetic attraction and the prosthesis is rejected prior to implantation.
RESULTS
None of the prostheses screened showed any magnetic attraction. As a control, steel wire was cut into pieces with dimensions similar to prostheses. These sections of wire were readily attracted to the magnet.
CONCLUSIONS
Intraoperative screening of metallic prostheses for magnetic susceptibility is possible using a sterile handheld pacemaker magnet.
目的
介绍一种在手术过程中评估金属耳科假体磁化率的技术。
研究设计
手术技术描述。
方法
在植入前，使用无菌手持式起搏器磁铁评估假体。将磁铁置于假体上方，假体直接放置在磁铁上。如有任何磁吸引迹象，则在植入前拒绝使用该假体。
结果
所筛查的假体均未显示出任何磁吸引现象。作为对照，将钢丝切成与假体尺寸相似的片段。这些钢丝片段很容易被磁铁吸引。
结论
使用无菌手持式起搏器磁铁在术中筛查金属假体的磁化率是可行的。
