Total compared with subtotal thyroidectomy in benign nodular disease: personal series and review of published reports.

OBJECTIVE

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.

CONCLUSION

Total thyroidectomy is the procedure of choice for the treatment of benign nodular goitre.
