The modern thyroid operation • Eradicate thyroid disease • A safe thyroid operation • Intra-operative evidence
Eradicate thyroid disease • Total lobectomy • Total thyroidectomy • Neck dissection (Central or Lateral) • Resection of upper aerodigestive tract • I-131 therapy
A safe thyroid operation • Preserve RLN and EBSLN • Preserve parathyroid function
Intra-operative evidence • Anatomic integrity - High-resolution photographs • Functional integrity - IONM of RLN - Intact blood supply to parathyroid
Recurrent laryngeal nerve palsy • Most common and serious complication • The leading reason for medicolegal litigation
Routine identification of RLN • Lower rates of RLN palsy • Gold standard of RLN treatment
Applications of IONM • Prevent RLN injury • Localize and identify RLN • Predict vocal function • Elucidate mechanism of RLN injury • Help preserve parathyroid

IONM is useful and helpful for • Anatomic variants of RLN • Difficult thyroid operation
Anatomic variants of RLN (Extralaryngeal branches, Non-RLN, Distorted RLN…etc) - important factors: • RLN injury • False results of IONM
Extralaryngeal branches of RLN • Branch to trachea • Branch to esophagus • Branch to inferior constrictor muscle • Anterior branch • Posterior branch

Difficult thyroid operation (Recurrent, substernal or large goiter , Thyroid cancer) Early localization & Definite identification An important step to prevent RLN injury
Preservation of parathyroid function • Preserve parathyroid with intact blood supply • Auto-transplantation for devascularized parathyroid
