To evaluate the rate of surgical complications during the change from subtotal resection to hemithyroidectomy or thyroidectomy over a period of 17 years.
All operations for benign goiter at our hospital were analyzed for the periods 1996-2002 (Group 1) and 2003-2012 (Group 2). The groups were compared for recurrent laryngeal nerve damage, hypocalcemia, and other surgical complications directly postoperatively.
In total, 1462 patients were operated on for goiter between 1996 and 2012. There were 1219 patients who underwent a primary thyroid operation, whereas 50 patients had surgery for recurrence. Postoperative histology revealed thyroid cancer in 193 patients (13.2%). In Group 1, 42.7% of all operated lobes were performed as lobectomies and 57.3% as subtotal resections; in Group 2, 74.4% were performed as lobectomies and 25.6% as subtotal resections. No differences were found for reduced vocal cord function (2.4% vs. 1.9%, p = 0.746) and recurrent laryngeal nerve paralysis in the postoperative laryngoscopy (2.9% vs. 1.8%, p = 0.675). Postoperative hypoparathyroidism was detected in 13.66% in Group 1 and in 19.80% in Group 2 after bilateral resections (p = 0.037). There was no difference in the rate of reoperations for cancer between both groups (43.4% vs. 52.1%, p = 0.182).
Surgical practice changed from subtotal to lobectomies for benign goiter over a period of 17 years without change in laryngeal nerve damage but with increasing rates of postoperative hypocalcemia.
