RESULTS REPORTED IN ?IMPACT OF EMG CHANGES IN CONTINUOUS VAGAL NERVE MONITORING IN HIGH-RISK ENDOCRINE NECK SURGERY?, BRAUCKHOF K., ET AL., WORLD J SURG (2016) 40:672?680. HYPOTHESIS: ?CONTINUOUS VAGAL INTRAOPERATIVE NEUROMONITORING (CIONM) OF THE RECURRENT LARYNGEAL NERVE (RLN) MAY REDUCE THE RISK OF RLN LESIONS DURING HIGH-RISK ENDOCRINE NECK SURGERY SUCH AS OPERATION FOR LARGE GOITER POTENTIALLY REQUIRING TRANSSTERNAL SURGERY, ADVANCED THYROID CANCER, AND RECURRENCE.? THIS ARTICLE WAS CONDUCTED TO EVALUATE WHETHER CONTINUOUS INTRAOPERATIVE NERVE MONITORING WOULD LOWER THE RISK OF RLN LESIONS DURING HIGH-RISK ENDOCRINE NECK SURGERY. THE NIM SYSTEM, EMG TUBE AND APS PROBE WERE USED TO RECORD THE NERVE FUNCTION THROUGHOUT THE PROCEDURES, NOT TO IDENTIFY NERVES. THE LOSS IN AMPLITUDE REPORTED IS A DIAGNOSTIC TOOL USED BY THE SURGEON TO AID IN PREVENTING NERVE INJURY. IF THE AMPLITUDE DROPS BELOW A CERTAIN PERCENT, THE SURGEON KNOWS THAT UNLESS HE MAKES AN ADJUSTMENT, VOCAL CORD INJURY COULD OCCUR. THIS STUDY REPORTS 1 PATIENT WHO SUSTAINED PERMANENT VOCAL CORD PALSY DUE TO AN INTRINSIC ?ACUTE THERMIC? LESION. ?IN TOTAL, THERE WERE 87 NERVES AT RISK (NAR), 42 ON THE RIGHT AND 45 ON THE LEFT SIDE. LARYNGOSCOPY ON THE FIRST POSTOPERATIVE DAY REVEALED THREE IMMOBILE VOCAL CORDS (3.4 %RELATED TO NAR) IN THREE PATIENTS. TWO WERE NORMAL AFTER 6 MONTHS, RESULTING IN A PERMANENT PALSY RATE OF 1.1 %RELATIVE TO NAR.?
