Key result
C-IONM shows similar rates of vocal cord paralysis compared to I-IONM during thyroid surgery.
Why the study?
The impact of vocal cord paralysis in thyroid surgery using intermittent and continuous intraoperative neuromonitoring needed evaluation.
Does continuous intraoperative neuromonitoring (C-IONM) reduce vocal cord paralysis compared to intermittent intraoperative neuromonitoring (I-IONM) in patients undergoing thyroid surgery?
Observational (n=147)
No
Does continuous intraoperative neuromonitoring (C-IONM) reduce vocal cord paralysis compared to intermittent intraoperative neuromonitoring (I-IONM) in patients undergoing thyroid surgery?
Absolute Event Rate: 3.9% vs 4.1%
Both intermittent and continuous intraoperative neuromonitoring are effective in predicting vocal cord paralysis during thyroid surgery, with no significant difference in outcomes between the two techniques.

Observational data link IONM use to VCP rates in thyroid surgery; leaves open need for randomized trials before practice change.
Cirillo et al. (2025) conducted an observational in Thyroid surgery (n=147). Continuous intraoperative neuromonitoring (C-IONM) vs. Intermittent intraoperative neuromonitoring (I-IONM) was evaluated on Temporary vocal cord paralysis. Continuous intraoperative neuromonitoring during thyroid surgery resulted in similar rates of temporary (3.9% vs 4.1%) and permanent (3.9% vs 0%) vocal cord paralysis compared to I-IONM.
