[Hypoparathyroidism after thyroid surgery].

The authors report their experience of hypoparathyroidism in thyroïd surgery: 538 patients underwent thyroidectomy, including 45% bilateral resections. In post operative period, accurate tests allowed to detect non permanent hypocalcemias in 60% of cases. Severe hypocalcemia (1.60 mmol/l) is necessary to engage a treatment by vitamin D. So, a soft thyroid microsurgery is the only one manner to preserve parathyroid stock. 46 patients had parathyroid transplantation, but the evaluation is difficult, because the amount of parathyroid gland without ischemia, left into the neck, is unknown. In summary, this technique is effective, but often useless in thyroid surgery.
