Preventing Inadvertent Parathyroidectomy during Thyroid Surgery - A Literature Narrative

Background: Accidental parathyroidectomy during thyroid surgery can lead to temporary or permanent hypocalcemia and serious morbidity. Proper identification of parathyroid glands during surgery can be an effective way to prevent this complication. Methods: The keywords “parathyroid gland,” “preserve,” “protect,” “inadvertent or accidental parathyroidectomy,” “surgery,” and “dissection” were used to search Medline and Embase databases. A total of 133 articles were selected after preliminary review, of which 80 indexed papers were reviewed for subject relevance. Results: Imaging techniques, such as the use of carbon nanoparticles or indocyanine green angiography, and operative techniques, such as meticulous capsular dissection of the thyroid gland, were associated with significantly improved rates of avoidance of inadvertent parathyroidectomy. Conclusion: During thyroid surgery, the use of imaging and careful operative techniques can prevent parathyroid injury. This, in turn, can prevent complications resulting from hypoparathyroidism such as tetany, ECG changes, and neurological sequelae.
