Secondary thyroidectomy in patients with prior thyroid surgery for benign disease: A study of 203 cases

Background. The goal of this study was to evaluate the complication rate of secondary thyroidectomy in patients with prior thyroid surgery for benign disease. Methods. Over an 8-year period, 203 thyroid reoperations were performed on 202 patients. All information relating to operative procedures, pathology, and complications was recorded prospectively. Results. There were 24 men and 178 women with a mean age of 52 years. Prior surgery was unilateral in 136 cases (67%) and bilateral in 67 cases (33%), and 14 patients (6.9%) had more than 1 previous thyroid operation. For eut hyroid or pretoxic recurrent nodular goiter, 190 reoperations were performe d and 13 reoperations were performed for recurrent thyrotoxicosis. Twenty-t hree cancers were found in a specimen (11.4%). Completion thyroidectomy was done in 143 patients. Postoperative complications occurred in 21 patients (10.4%): recurrent laryngeal nerve palsy (7 patients), hypocalcemia (8 pati ents), hematoma requiring surgical evacuation (5 patients), and wound infec tion (1 patient). Complications remained permanent in 4 patients (2%). Conclusions. The permanent complication rate is higher in thyroid reoperati ons than in primary thyroid operations. However, we believe that this 2% ra te is low enough to allow reoperation whenever it is necessary, provided pr ecise operative rules are respected.
