“…In many studies (Bergamaschi et al, 1998;Erolu et al, 1998;Pappalardo et al, 1998;Bron and O′Brien, 2004;Rosato et al, 2004;Zambudio et al, 2004;Ozbas et al, 2005), although parathyroid hormone levels were not assessed, hypoparathyroidism was accepted as the cause of hypocalcaemia. Hypoparathyroidism constituted the majority of the complications after total thyroidectomy in most series (Erolu et al, 1998;Pappalardo et al, 1998;Rosato et al, 2004;Zambudio et al, 2004;Ozbas et al, 2005). The incidence of hypoparathyroidism varied in different series with the dominance of temporary nature (Bergamaschi et al, 1998;Rosato et al, 2004;Zambudio et al, 2004;Ozbas et al, 2005).…”
