Long term follow-up of hyperthyroid patients treated by subtotal thyroidectomy.
The early and long term complications of subtotal thyroidectomy in 306 hyperthyroid patients (multinodular goitre and diffuse hyperplasia) followed for up to 30 yr are reviewed. There were no perioperative deaths. Sixteen patients (5.2 per cent) had transient symptomatic hypocalcaemia, while 9 (2.9 per cent) had permanent hypocalcaemia. Permanent unilateral vocal cord paralysis occurred in 11 (3.6 per cent) patients (1.8 per cent of nerves at risk). Cumulative per cent (+/- s.e.m.) relapse and hypothyroid rates at 30 yr (life-table analysis) were 15.6 +/- 2.4 per cent and 20.5 +/- 2.1 per cent, respectively. Lifelong follow-up of post-thyroidectomy patients is mandatory because of the risk of relapse of hypothyroidism.
