New surgical approach may reduce voice damage in thyroid operations
NCT ID NCT07532889
First seen Jun 25, 2026 · Last updated Sep 01, 2026 · Updated 3 times
Summary
This study compares two ways of finding and protecting the nerve that controls the voice box during thyroid surgery. About 430 adults having their thyroid removed will be randomly assigned to either a newer medial approach or the standard lateral approach. The goal is to see which method causes fewer nerve injuries, shorter hospital stays, and better voice recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- surgical procedure (medial vs lateral dissection approach to the recurrent laryngeal nerve)
- What this could lead to
- If one approach proves safer, it could become the new standard for thyroid surgery, reducing voice complications and hospital stays.
- What could go wrong
- This is a single-center trial with no blinding, so results may not apply broadly. The study only compares surgical techniques, not a new drug or device.

Inclusion Criteria: * All patients undergoing a total thyroidectomy or hemithyroidectomy under the care of the participating surgeons Exclusion Criteria: * Age less than 19 years old * Previous thyroid or parathyroid surgery, substernal goiter, preoperative vocal cord palsy (VCP) * Evidence of lateral or central neck lymph node metastases * Intentional iatrogenic transection of the RLN due to tumor invasion * Failure to assess real-time RLN functioning due to equipment issues with the IONM setup * Presurgical dissection amplitude under 100uV * Patient refusal to participate in the study * Intraoperative decision to switch to a different approach to identifying the RLN
