What was measured

Total number of frozen sections conducted for patients undergoing repeat surgery or bilateral neck explorations. Frozen sections were conducted to confirm that the parathyroid tissue for the targeted over-acting parathyroid was removed. Results reflect whether participants had a frozen section conducted.

Groups in this outcome

PTeye

The surgeon will use the PTeye as an intraoperative tool to identify if a suspect tissue is a parathyroid or not, during the parathyroid surgery. PTeye: The surgeon will first take 5 baseline NIRAF measurements on the thyroid gland (or neck muscle, if thyroid is absent) using the disposable sterile fiber probe that is connected to the PTeye console (see Figure 1), as per device functionality requirements.

Standard of Care

The surgeon will rely solely on her/his surgical experience in identifying the parathyroid glands during the operations.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
