Background: Though minimally invasive video-assisted thyroidectomy (MIVAT) offers many advantages over traditional thyroid surgery, its adoption in North America has been limited. This study analyzes the largest series of MIVAT in North America to explore its safety. Methods: A prospectively maintained database of all patients undergoing thyroid surgery by a single surgeon from 2003 to 2011 at an academic tertiary care medical center was evaluated. Demographic information, surgical and pathologic data, and postoperative outcomes were analyzed. Results: Beginning in 2005, a total of 260 MIVATs were performed during the study period. Outpatient surgery was accomplished in 234 MIVATs (90%). MIVAT patients were predominantly young (46.8 ± 14.8 years vs 52.4 ± 14.6 years for conventional thyroidectomy) and female (88.5% vs 75.5% for conventional thyroidectomy). There were no cases of permanent hypoparathyroidism or permanent recurrent laryngeal nerve dysfunction. Observed complications included transient recurrent laryngeal nerve dysfunction (n = 10; 3.8%), cellulitis (n = 1; 0.4%), and temporary hypocalcemia (n = 6; 2.3%). The overall complication rate for MIVAT (6.5%) was lower than the overall complication rate in conventional thyroidectomy (18.5%, P <.0001). Conclusion: MIVAT can be performed safely with a low complication profile in a high-volume practice. The safety of MIVAT represented by this experience supports broader adoption across surgical practices.
