Incidence of hypo-parathyroidism following thyroidectomy in a prospective study of 108 consecutive African patients

In a prospective study of 108 consecutive African patients in the University of Benin Teaching Hospital undergoing thyroidectomy over the period 1986-1990, one patient had overt hypoparathyroidism while six others presented with the latent form, giving an overall incidence of 6.5 pc. Hypoparathyroidism was associated with large adherent goitres involving extensive dissection. Routine post-operative serum calcium is advocated so as not to miss latent hypoparathyroidism. Identification of the parathyroids with preservation of the blood supply should be carefully observed so as to minimise the incidence of hypoparathyroidism.
