Study summary

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).

What researchers measure

Primary outcomes

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

    Time frame: 1 week after surgery

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

    Time frame: 3 weeks after surgery
