Major post-operative complications of thyroid surgery: preventable or not?

Factors responsible for major complications following thyroid surgery in 598 patients were studied. Patients with non toxic multinodular goiter involving both lobes of thyroid constituted the maximum bulk subjected to thyroidectomy. The most frequent procedure was bilateral subtotal thyroidectomy. Reactionary hemorrhage occurred in 6 patients, all following bilateral procedures and among them 5 patients developed tension hematoma with respiratory obstruction despite the presence of a drain. Temporary vocal cord palsy was observed in 7 patients whereas one patient subjected to total thyroidectomy with neck dissection for papillary carcinoma of thyroid developed permanent right vocal cord palsy. Temporary parathyroid insufficiency was seen in 51 patients and one patient developed permanent hypoparathyroidism. Incidence of parathyroid insufficiency was higher in bilateral procedures as compared to unilateral ones. There was no operation related death in this series, but complications like hemorrhage, vocal cord palsy and parathyroid insufficiency following thyroid surgery are still a deep concern.
