Male sex and positive margins were negative prognostic factors. Endoscopic resection did not show an increased risk of death compared with more extensive surgical approaches. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1737-E1745, 2016.

Endoscopic techniques, in properly selected patients, were associated with a favorable oncologic outcome and a statistically significant reduction in both complication rate and hospitalization time. This study supports the role of endoscopic techniques in surgical treatment of ethmoid adenocarcinoma.

This preclinical study demonstrates the potential of the ABC system. Although the ABC may improve preoperative anatomical assessment of the frontoethmoidal area, validation in a clinical setting is required.

POSTERSResults: Thyroid dissection was performed in a total of 10 pigs. Two were "open" procedures to learn the porcine anatomy. Eight were endoscopic procedures. Of them 5 used three 5-mm incisions and 3 used three 2-to 3-mm incisions for surgical tools and a 5-mm incision for the endoscopic camera. In all cases the thyroid was completely dissected with the recurrent laryngeal nerve (RLN) identified and preserved. In 5 cases the thyroid was removed through the floor of the mouth. There was no major bleeding in the live pigs, and all the vital structures were identified and preserved.Conclusion: Endoscopic thyroidectomy using miniature camera and tools in a porcine model seems to be feasible without major complications. The advantages of this approach include minimal scars and improved visualization. We believe that there is room for further development of minimal invasive techniques for thyroid surgery.
