To this day, two distinct operative strategies dominate SHPT surgical management in clinical practice: subtotal PTX (SPTX), wherein ≈31⁄2 glands are excised, leaving a remnant (<100 mg) in situ, to preserve endogenous PTH and mitigate permanent hypocalcemia; and total PTX with autotransplantation (TPTX + AT), which removes all cervical parathyroid tissue, but then reimplants a small parathyroid tissue specimens—usually in the forearm—in order to minimize recurrence, while also maintaining some PTH reserve [9]. Here, PTH is linked to Hypocalcemia.
