RESUMO
Introduction: Endoscopic thyroidectomy (ET) has been successfully established as an excellent surgical approach. This study summarizes and describes the crucial anatomical landmarks for clinical applied anatomy in trans-areolar ET, which may help further improve the quality and safety of trans-areolar ET. Materials and Methods: Five hundred forty patients who underwent trans-areolar ET from January 2015 to June 2018 at our institution were evaluated. Several crucial anatomical landmarks were described during the surgical procedures. The surgical outcomes, including the operative time, conversion, intraoperative blood loss, postoperative complications, and postoperative stay, were collected. Results: All patients successfully underwent trans-areolar ET without conversion. The mean operative time was 142.18 ± 49.91 minutes (150.84 ± 50.32 minutes for total thyroidectomy and 110.20 ± 32.4 for lobectomy with isthmusectomy). The mean intraoperative blood loss was 20.45 ± 10.89 mL. The postoperative stay was 5.42 ± 1.49 days. The postoperative complication rate was 7.78%, including transient hypocalcemia in 30 patients, transient recurrent laryngeal nerve palsy in 3 patients, and skin ecchymosis in 9 patients. Conclusions: An understanding of crucial anatomical landmarks for clinical applied anatomy may improve the quality and safety of trans-areolar ET and subsequently help promote the development of ET.
