    Description of Event or Problem · 1

    IT WAS REPORTED THAT THE FOLLOWING EVENT OCCURRED DURING A SECONDARY MANDIBLE RESECTION PROCEDURE ON (B)(6) 2014. THIS WAS A REVISION OF THE INITIAL MANDIBLE RESECTION SURGERY, DUE TO A RECURRENCE OF CANCER. INITIAL RESECTION SURGERY WAS PERFORMED ON AN UNKNOWN DATE. THE INITIAL PATIENT SPECIFIC PLATE CONTOURING MATRIX MANDIBLE PLATE AND CONDYLAR HEAD ADD-ON SYSTEM WERE REMOVED. DURING THE REVISION SURGERY, THE SURGEON HAD DIFFICULTY ENGAGING THE SCREWS OF THE CONDYLAR ADD-ON PLATE TO THE PATIENT SPECIFIC PLATE CONTOURING CUSTOM IMPLANT. THREE OF THE SCREWS STRIPPED, AND COULD NOT BE USED. THE SURGEON HAD TO STOP, REASSESS THE BEND OF THE PLATE AND THEN BEND AND FILE THE PLATE A LITTLE MORE IN ORDER TO DECREASE THE INTERFACE BETWEEN THE PLATE AND THE CUSTOM IMPLANT SO THAT THE SCREWS WOULD ENGAGE THE IMPLANT. ANOTHER SET WAS OPENED FOR ADDITIONAL SCREWS. THE PROCEDURE WAS PROLONGED BY 25 MINUTES TO MANIPULATE THE PLATE AND SECURE ADDITIONAL SCREWS TO COMPLETE THE PROCEDURE. PATIENT WAS STABLE FOLLOWING THE REVISION SURGERY. THIS REPORT IS 2 OF 4 FOR (B)(4).
