Magnet dislodgement in cochlear implantation: Correction utilizing a lasso technique

Summary Objectives Magnet displacement is recognized as an uncommon, major complication following cochlear implant surgery. This complication necessitates operative intervention exposing patients to further surgical risk and morbidity. The purpose of this paper is to describe a unique surgical technique for securing internal magnets which have dislodged from their silicone housing within the internal receiver-stimulator. Methods A case involving a 5-year old cochlear implant patient is reviewed. This patient experienced magnet displacement on two separate occasions. A new lasso technique for re-securing the internal implant magnet is described in detail. Results The patient's implant remains fully functional with a securely placed internal magnet 36 months post-operatively. Conclusions When compared to other surgical options, the “lasso” technique represents a simple, safe, efficient and cost-effective surgical option with minimal morbidity.
