Assessing Benefits of NIRAF Detection for Identifying Parathyroid Glands During Total Thyroidectomy.
Purpose
This study describes a single center, randomized, single-blinded clinical trial to assess the clinical benefits of the use of near infrared autofluorescence (NIRAF) detection with an FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands (PGs) during total thyroidectomy (TTx). It compares risk-benefits and outcomes in TTx patients where NIRAF detection with PTeye for parathyroid identification is either used or not used.
Conditions
- Postoperative Hypoparathyroidism
- Thyroid Neoplasms

Inclusion Criteria
(i) All patients eligible for total thyroidectomy (TTx), with or without lymph node dissection. (includes patients undergoing a TTx who have undergone a prior neck exploration for parathyroid disease or other but have an intact thyroid). (ii) All patients undergoing completion thyroidectomy.
Exclusion Criteria
(i) Patients with concurrent parathyroid disease. (ii) Patients with incidental enlarged parathyroid discovered during TTx. (iii) Patients undergoing thyroid lobectomy/partial thyroidectomy.

- Intervention Model Description
- NIRAF detection technology is used as an adjunctive tool for intraoperative parathyroid identification in patients who undergo total thyroidectomy (TTx) with or without lymph node dissection (LND) in the interventional group. Generic Name of Device: Parathyroid Autofluorescence Detection Device (NIRAF detection technology). The Parathyroid Autofluorescence Detection Device consists of a disposable fiber-optic probe that emits non-ionizing radiation from a NIR 785 nanometer (nm) laser source, and also transmits the resulting tissue NIRAF to a photo detector. The 785 nm laser source emits a maximum power of 20 Milliwatts (mW). The device has an FDA clearance for clinical use in general surgeries and dermatological use (Class 2 device).

Detailed Description
Inadvertent damage or excision of a healthy parathyroid gland (PG) following a total thyroidectomy (TTx) could result in transient hypocalcemia (< 6 months) in 5 - 35% of cases or permanent hypocalcemia (> 6 months) in 7% of the patients (1, 2). In both of these circumstances, patients would require calcium and active vitamin D supplementation in addition to a potentially prolonged hospital stay and/or unplanned hospital readmission adding to unnecessary burden and healthcare costs. These complications could be minimized with label-free intraoperative PG identification using near infrared autofluorescence (NIRAF) detection with a fiber-probe based approach (3 - 5) as utilized in 'PTeye', which is medical device that was recently FDA-cleared (6). However, the true impact of this particular NIRAF-based approach on patient outcomes is yet to be determined The aim of this prospective single blinded randomized study is to compare 2 groups of patients: TTx patients operated using NIRAF detection technology with PTeye as adjunct tool (NIRAF+) vs. patients operated without the adjunct technology (NIRAF-). The main objective of this study is to assess the benefit of intraoperative use of NIRAF detection technology via PTeye during TTx procedures with regard to postoperative hypocalcemia, PG identification, PG auto-transplantation and inadvertent resection rates compared to standard of care.
