“…Thyroidectomy is very effective, albeit at the expense of a low but unavoidable morbidity (notably voice disabilities). Postoperative recurrences, however, do occur in 4–19% ( Berghout et al ., 1989 ), and apparently are not prevented by postoperative treatment with thyroxine ( Geerdsen & Froland, 1986; Hegedus et al ., 1987 ; Bistrup et al ., 1994 ; Berglund et al ., 1998 ). Thyroxine given in TSH‐suppressive doses is moderately effective.…”
