Intraoperative neuromonitoring of recurrent laryngeal nerve: Initial experience

  • Clinical Study
  • Published:
Hellenic Journal of Surgery

Abstract

Background - Aim

The role of intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve (RLN) in thyroid surgery remains controversial. We present herein the initial experience in the use of the IONM of the RLN in our Department. The objective of the present study was to determine the potential role of IONM in reducing postoperative RLN palsy rate

Methods

Between June 1996 and August 2010, 696 patients underwent total thyroidectomy due to benign or malignant conditions of the thyroid gland. From January 2008 to August 2010, IONM of the RLN was applied in 84 of these patients in order to identify and preserve the RLNs, whereas conventional RLN identification was used in the remaining 612 patients.

Results

Eighty four total thyroidectomies and two reoperations were performed using IONM of the RLN with 170 nerves at risk and 612 total thyroidectomies and 38 re-operations with 1262 nerves at risk were performed by routine identification. The incidence of transient and permanent RLN paralysis based on nerves at risk was 0.59% (1 of 170) and 0% (0/170) with intraoperative neuromonitoring and 0.24% (3 of 1262) and 0% (0/1262) with conventional RLN identification.

Conclusion

Neuromonitoring of the RLN during thyroid surgery could not be demonstrated to reduce RLN injury significantly, compared with routine RLN identification. Nevertheless, its application can be considered in selected high-risk thyroidectomies. This technological process may render safer thyroidectomies performed by junior surgeons or surgeons with low case-load.
