ObjectiveTo recognize the intraoperative recognition of parathyroid gland optical technology and explore its application value in thyroid surgery to protect the parathyroid gland.MethodsLiterature review was conducted on the principle and application status of intraoperative recognition of parathyroid gland optical technology by using " thyroidectomy” " parathyroid gland” " Near-Infrared imaging” " laser speckle contrast imaging”, and " optical coherence tomography” as retrieval terms to retrieve literatures.ResultsIntraoperative optical technique alone or in combination with contrast agent could improve the recognition rate of parathyroid gland, reduce the damage of feeding vessels, and thus reduce the incidence of postoperative hypocalcemia.ConclusionsTraditional intraoperative parathyroid gland recognition methods needs to be improved in real-time protection effectiveness and accuracy, and the combination of new optical technology and contrast agent can largely make up for these shortcomings, but there are still obstacles in the promotion.
