Amount of thyroid tissue left after subtotal thyroidectomy is
Total thyroidectomy involves excision of all visible thyroid tissue. Near-total thyroidectomy is complete resection on one side while leaving a remnant of thyroid tissue on the contralateral side, leaving less than 1 g of tissue adjacent to the RLN at the ligament of Berry. Subtotal thyroidectomy leaves a remnant of thyroid tissue bilaterally. Subtotal resection of each lobe is carried out, leaving a remnant of 4-5 g on each side. Thyroid lobectomy typically includes removal of the thyroid isthmus and pyramidal lobe (if present). Source : Sabiston 20th edition Pg : 912 Bailey and Love 26th edition Pg : 761
