Modified version of minimally invasive open thyroidectomy using an unilateral incision

Background/objective: Open thyroidectomy has been the standard approach for patients undergoing thyroidectomy. However, this approach leads to prominent scars, hypesthesia, paresthesia, and uncomfortable sensations. We aimed to describe our modified technique of minimally invasive open thyroidectomy (MIT) and to compare the results with those of conventional thyroidectomy. Methods: This study included 880 patients who underwent surgery between January 2016 and December 2016. Modified MIT was performed in 249 patients (28.3%), and conventional thyroidectomy was performed in the remaining 631 patients. Results: Lobectomy was performed in the majority of cases (MIT 204 [81.9%] vs. conventional 429 [67.9%]). There were no significant differences in complications between the two approaches (6 [2.4%] vs. 8 [1.3%]). Patients who underwent surgery using the minimally invasive approach had a shorter operative time (77.99 ± 34.5 vs. 91.23 ± 36.58 min) and were discharged earlier (2.4 ± 0.8 vs. 3.2 ± 0.8) than those who underwent conventional thyroidectomy. Conclusion: Modified MIT is a safe alternative to standard open thyroidectomy and allows the performance of bilateral total thyroidectomy with proper central compartment neck dissection. Level of evidence: 2b.
