To evaluate the outcome after total and subtotal thyroidectomy for the treatment of single and multinodular goitres in two comparable groups of patients.
Design:
Prospective randomised study.
Setting:
University hospital, Italy.
Subjects:
141 Patients operated on for benign goitre from 1975–85.
Interventions:
69 Patients were randomised to have total thyroidectomy and 72 subtotal thyroidectomy by standard techniques.
Main outcome measures:
Temporary or permanent palsy of the recurrent laryngeal nerve, temporary or permanent hypoparathyroidism, recurrence of the goitre, and the incidence of iatrogenic injuries after completion thyroidectomy.
Results:
Patients were followed up for a median of 14.5 years (range 10–21). After total thyroidectomy 2 patients (3%) developed temporary palsy of the recurrent laryngeal nerve but there were no permanent lesions; and 24 (35%) developed temporary and 2 (3%) permanent hypoparathyroidism. After subtotal thyroidectomy 2 (3%) developed temporary and 1 (1%) permanent palsy of the recurrent laryngeal nerve; and 13 (18%) developed temporary and 1 (1%) permanent hypoparathyroidism. In addition, there were 10 recurrent goitres (14%). After completion thyroidectomy (n = 9) there were 2 cases of temporary and 1 of permanent palsy of the recurrent laryngeal nerve, and 2 cases of temporary and 2 of permanent hypoparathyroidism.
