Abstract
BACKGROUND: Several studies have sought to identify predictors of postoperative hypocalcemia after total thyroidectomy; however, there have been conflicting results regarding the impact of preoperative vitamin D deficiency.
METHODS: The medical records of patients undergoing total thyroidectomy were retrospectively reviewed. The number of parathyroid glands identified or reimplanted at the time of surgery was used as a marker of transient parathyroid gland damage.
RESULTS: Sixty-seven patients were included in the study. Vitamin D deficiency was a significant predictor of hypocalcemia in patients in whom ≥3 parathyroid glands were identified, but not in patients in whom 0-2 parathyroid glands were identified intraoperatively (odds ratio [OR] 5.8; P = .036).
CONCLUSION: Vitamin D deficiency is a significant predictor of postoperative hypocalcemia in patients in whom ≥3 parathyroid glands are identified intraoperatively, but not in patients who sustain minimal transient damage to the parathyroid glands.
