About International Neural Monitoring Study Group

The International Neural Monitoring Study Group INMSG was founded to serve the emerging field of neurophysiologic monitoring of the laryngeal nerves in thyroid and parathyroid surgery.

The INMSG is a multidisciplinary international group of surgeons and researchers selected based on clinical experience and expertise in thyroid and parathyroid surgery, neural monitoring, and related fields. The INMSG includes surgeons (otolaryngologists, general surgeons, and endocrine surgeons), laryngologists, voice and laryngeal electromyography (EMG) specialists, anesthesiologists, neurophysiologists and technologists.

As defined by the INMSG, neurophysiologic monitoring includes any measure employed to assess the ongoing functional integrity of the laryngeal nerves in thyroid surgery.

Intraoperative neurophysiological monitoring (IONM) has evolved over the last several decades. Its mission is protection of the patient’s nervous system. Neurophysiologic signals are monitored continuously during thyroid surgery for adverse EMG changes, detection of which enables corrective action. In addition to detection of change, surgical guidance for laryngeal nerve identification, confirmation and dissection can be offered in specialized circumstances.

The INMSG published guidelines on recurrent laryngeal nerve (RLN) and external branch of the superior laryngeal nerve (EBSLN) IONM standards for monitored thyroid and parathyroid surgery.

INMSG is dedicated to the advancement of quality neurophysiologic monitoring services for protection of the laryngeal nerves.

INMSG serves as the leading organization for the field of neurophysiological assessment and monitoring of the laryngeal nerves in thyroid and parathyroid surgery.

Aim of the INMSG is to improve quality of IONM, reduce inappropriate variations in IONM technique, adhere to strict standardization, fosters the growth and stature of neurophysiological monitoring, research, clarify limits, improve and update guidelines, implement IONM courses, develops quality standards for practice and training, define unequivocal reference of RLN neurophysiology and pathology, refine EBSLN monitoring and evaluate new developing technology as continuous monitoring (C-IONM).

INMSG provides a forum for education and dissemination of knowledge in the field of thyroid and parathyroid surgery.

The INMSG was formed in 2006 as a working group by and is associated with the European Society of Endocrine Surgeons (ESES).
