ObjectivesCompared to adult patients undergoing thyroid surgery, pediatric patients have higher rates of hypoparathyroidism often related to parathyroid gland (PG) inadvertent injury or devascularization. Previous studies have shown that near‐infrared‐autofluorescence (NIRAF) can be reliably used intraoperatively for label‐free parathyroid identification, but all prior studies have been performed in adult patients. In this study, we assess the utility and accuracy of NIRAF with a fiber‐optic probe‐based system to identify PGs in pediatric patients undergoing thyroidectomy or parathyroidectomy.MethodsAll pediatric patients (under 18 years of age) undergoing thyroidectomy or parathyroidectomy were enrolled in this IRB‐approved study. The surgeon's visual assessment of tissues was first noted and the surgeon's confidence level in the tissue identified was recorded. A fiber‐optic probe was then used to illuminate tissues‐of‐interest with a wavelength of 785 nm and resulting NIRAF intensities from these tissues were measured while the surgeon was blinded to results.ResultsNIRAF intensities were measured intraoperatively in 19 pediatric patients. Normalized NIRAF intensities for PGs (3.63 ± 2.47) were significantly higher than that of thyroid (0.99 ± 0.36, p < 0.001) and other surrounding soft tissues (0.86 ± 0.40, p < 0.001). Based on the PG identification ratio threshold of 1.2, NIRAF yielded a detection rate of 95.8% (46/48 pediatric PGs).ConclusionOur findings indicate that NIRAF detection can potentially be a valuable and non‐invasive technique to identify PGs during neck operations in the pediatric population. To our knowledge, this is the first study in children to assess the accuracy of probe‐based NIRAF detection for intraoperative parathyroid identification.Level of EvidenceLevel 4 Laryngoscope, 133:3208–3215, 2023
