D, 1–2 parathyroid preservation in situ without parathyroid autotransplantation; E, 1–2 parathyroid preservation in situ + at least 1 parathyroid autotransplantation; F, 3–4 parathyroid preservation in situ + at least 1 parathyroid autotransplantation. PTH, parathyroid hormone; POD, postoperative day.
