AI Article Synopsis
Article Abstract
Background: Recently, several devices exploiting the near-infrared autofluorescence (NIR-AF) of parathyroid glands (PGs) have been developed. Nevertheless, their impact on both preserving PGs from inadvertent surgical dissection and on post-surgical hypoparathyroidism (hypoPTH) is controversial.
Methods: A retrospective study of 845 patients undergoing thyroid surgery in 2 academic tertiary centres was conducted. In 291 patients, a NIR-AF device was used during surgery to identify PGs. The characteristics of the cohort were examined. The number of PGs identified during surgery, missed PGs, auto-transplants, inadvertent parathyroidectomies, as well as the occurrence of transient and permanent hypoPTH, were analysed.
Results: The use of NIR-AF device resulted in a higher identification of PGs (92% versus 88%, p = 0.0008), and a significant reduction in the number of PGs inadvertently removed and detected on histopathological examination (4.7% versus 6.5%, p = 0.045). An increase in PG auto-transplantations was observed in the NIR-AF + group (10.4% versus 3.5%, p < 0.0001). The use of NIRAF did not significantly impact the occurrence of either transient or permanent hypoPTH.
Conclusion: Intraoperative NIR-AF detection is a promising technology to reduce incidental parathyroidectomies in thyroid surgery. The impact of this technology on the occurrence of post-surgical hypoPTH needs to be furtherly investigated.

Purpose: Near-infrared autofluorescence is a new technology in thyroid surgery to better localize and preserve parathyroid glands. The purpose of this study is to assess if the adoption of NIR-AF can improve in short-, medium-, and long-term post-operative calcium and PTH levels compared to conventional "naked eye" surgery in patients undergoing TT for benign or malignant conditions.
Methods: 134 patients undergone total thyroidectomy between January 2020 and June 2022; 67 were treated with conventional thyroidectomy, the other 67 underwent surgery adopting an autofluorescence detecting device.

Purpose: To describe our personal experience during aclassic complete thyroidectomy adopting both intraoperative neural monitoringand near-infrared autofluorescence.
Methods: In October 2021, 20 patients underwent totalthyroidectomy for benign and malignant conditions: 13 patients were affected bymultinodular goiter, 2 by Graves' disease, and 5 by indeterminate lesions (3Tir-3B and 2 Tir-3A). For each patient, intraoperative neural monitoring of therecurrent laryngeal nerve and near-infrared autofluorescence were used.

Contrast-free autofluorescence (AF) of the parathyroid glands (PTGs) and thyroid tissue occurs in the near-infrared (NIR) spectrum on excitation by light in the upper range of the visible spectrum or lower NIR spectrum. , PTGs autofluoresce more brightly than thyroid (by a factor of 2-20 times) and appear as a bright spot against surrounding thyroid, muscle or fat on a processed image which is generated in real-time. NIR-AF of PTGs was first described in 2009 although NIR-AF had previously been used in several other clinical applications.
