Background:
Mobilization of the thyroid during an endoscopic thyroidectomy (ET) via a breast approach was originally carried out from the lower pole to the upper pole (upward approach). Here, we applied a modified circular approach to achieve better exposure of the surgical field, in which the path of thyroid mobilization started from the isthmus and resembled a circle. The purpose of this study is to evaluate the safety and feasibility of the circular approach compared with the upward approach.
Patients And Methods:
From December 2008 to June 2013, 144 patients who underwent attempted ET via a breast approach were enrolled in this study, and their clinical outcomes were evaluated.
Results:
In total, 141 of 144 procedures were successfully performed under endoscopy, including 60 (42.6%) via the upward approach and 81 (57.4%) via the circular approach. The mean operating time was significantly shorter in the circular approach group than in the upward approach group (90.6 minutes versus 112.5 minutes for hemithyroidectomy; 109.5 minutes versus 133.2 minutes for subtotal thyroidectomy; P<.05). Furthermore, the incidence of the transient recurrent laryngeal nerve palsy decreased in the circular approach group compared with the upward approach group (2.5% versus 13.3%; P<.05).
Conclusions:
These results seem to indicate that the circular approach is a better method of mobilizing the thyroid, especially for large nodules located in the lower pole of the thyroid. This approach may provide a better view of the surgical field, reduced operating times, and fewer postoperative complications.
