Intra Operative Continuous Laryngeal Nerve Monitoring During Thyroid Surgery and Interpretation of the Post-operative Voice Quality in Relation to the Electromyography Data Obtained During Surgery

During thyroid surgery the laryngeal recurrent nerves (and for this reason the voice quality) are at risk. Therefore intra operative continuous neuromonitoring could help to prevent harm to these nerves. Electromyographic data (EMG values) are collected during surgery (1). In the postoperative follow-up period detailed voice analysis is performed (2): subjective auditive perceptive evaluation and videostroboscopy. Analysis and comparison of (1) and (2) will be performed in order to find out if we can find a predictive correlation between the EMG data (1) and the voice quality (2).

Treatment and study plan

Continuous nerve monitoring

Procedure

Continuous nerve monitoring is performed during thyroid surgery.

Primary outcomes

Detailed voice analysis to find a predictive correlation between the EMG data and the voice quality, after thyroid surgery.

Time frame: 1 week after surgery

The primary outcome is to check if by continuous vagal nerve stimulation reversible damage to the recurrent laryngeal nerve can be foreseen, and therefore avoided. The detailed voice analysis that is used, consist of subjective auditive perceptive evaluation and videostroboscopy.
