Reoperative thyroidectomy for benign thyroid disease

Background. Subtotal thyroidectomy for benign thyroid disease (BTD) may lead to delayed recurrence, thus necessitating reoperative surgery. We describe our experience with reoperative thyroidectomy for BTD and recommendations for definitive primary management. Methods. Patients undergoing thyroid surgery between 2003 and 2007 by a single surgeon were prospectively assessed. Numerous clinical parameters were evaluated, including time interval between primary and reoperative surgery and complications. Results. In all, 321 thyroidectomies were identified: 45 were reoperative and 22 were related to BTD after primary surgery done elsewhere. Median interval between the primary and reoperative procedure was 8.5 years. No recurrences followed total thyroidectomy or total thyroid lobectomy. There were no cases of permanent or transient recurrent laryngeal nerve (RLN) injury related to reoperative surgery. There was 1 case of transient hypocalcemia. Conclusions. Although reoperative thyroidectomy can be performed safely in the hands of experienced surgeons, a thorough initial surgical procedure should obviate the need for exposure to this additional risk.
