[Risk to the parathyroids in thyroid surgery. Value of parathyroid reimplantation. Apropos of a homogenous series of 350 operations].

Based on a series of 350 thyroidectomies, of which 214 were total or practically total, the risk of postoperative sequelae due to hypoparathyroidism was investigated. The frequency of this complication was particularly high (11.43 p. 100) during the immediate postoperative period, probably due to the amount of thyroid excised in this series. Long-term follow-up showed that only 15 patients (4.29 p. 100) were still being treated with vitamin D derivatives. Parathyroid reimplantation, whether "accidental" during simple thyroidectomy or "as a principle" in jugulocarotid and recurrent nerve gland curettage (25 cases) appears a valid method for avoiding long-term hypoparathyroidal sequelae.
