EVIDENCE ON CLINICAL VALUE
IONM DURING THYROID/PARATHYROID/EAR SURGERIES OR PAROTIDECTOMIES - SUMMARY
EVIDENCE FROM SINGLE-BLINDED RCTs: INTERMITTENT IONM REDUCED THE INCIDENCE OF NERVE PALSY/PARESIS DURING TOTAL THYROIDECTOMIES AND BILATERAL THYROID SURGERIES
REAL-WORLD EVIDENCE FROM 8,900 PATIENTS IN GERMANY: INTERMITTENT IONM REDUCED THE RATE OF EARLY & PERMANENT PALSIES
Intermittent IONM significantly reduced the rate of overall postoperative early & permanent RLN palsies among thyroid surgery patients and patients undergoing high-risk procedures (recurrent goiter, thyroid carcinoma) compared to visualization alone20
EVIDENCE FROM A NON-RCT: INTERMITTENT IONM REDUCED THE RATE OF TRANSIENT & PERMANENT PALSIES
Compared to visualization, intermittent IONM significantly reduced the rate of transient and permanent palsies of the RLN (nerves at risk)21
EVIDENCE FROM A RCT: INTERMITTENT IONM ENHANCED THE RECOVERY OF FACIAL NERVE FUNCTION
The severity of voice disorders was significantly reduced by intermittent IONM compared to visualization alone following thyroid surgery22
EVIDENCE FROM A RCT: INTERMITTENT IONM ENHANCED THE RECOVERY OF FACIAL NERVE FUNCTION26
EVIDENCE FROM A RCT: INTERMITTENT IONM
RESULTED IN EARLIER RECOVERY OF FACIAL FUNCTION
Compared to visualization, a significantly higher percentage of patients had earlier recovery of facial function after surgery for recurrent pleomorphic adenoma when facilitated by intermittent IONM26
EVIDENCE BASED ON POOLED ANALYSIS: INTERMITTENT IONM RESULTED IN A HIGHER RATE OF FACIAL NERVE PRESERVATION
Intermittent IONM resulted in a significantly higher percentage of patients with FN preservation compared to visualization after surgery for acoustic neuroma25
INTERMITTENT IONM REDUCED THE RATE
OF FACIAL NERVE PARESIS
IONM significantly reduced the rate of postoperative FN paresis following parotidectomies compared to visualization in all patients, and in patients without comorbidities and no prior surgeries27
CONTINUOUS IONM REDUCED THE RATE
OF PERMANENT PALSIES
