Background: Endoscopic thyroid surgery is gaining wide acceptance; however, existing endoscopic methods for thyroidectomy have shown several limitations. Recently, a transoral technique using video assistance and endoscopy has been reported for thyroidectomy. The aim of this study was to define a new technique of transoral thyroidectomy using a mandibular periosteal approach to complement other types of natural orifice surgery and minimally invasive surgery. Materials and Methods: Transoral periosteal thyroidectomies were performed in seven living pigs to evaluate the feasibility and safety of the new approach. Total thyroidectomies were performed in all animals. Follow-up examinations were carried out for 7 days and followed by autopsy. Results: Through three trocars in the mandibular periosteal area, it was possible to create a working space under the platysma muscle and to reach the pretracheal area. Total thyroidectomies were also performed via the transoral, mandibular periosteal approach without complications in seven orally intubated living pigs. Postoperatively, the white blood cell count remained normal in all cases. On the postoperative sacrifice of the pigs, three locally encapsulated seromas were observed. Both recurrent laryngeal nerves were intact in all cases. Conclusions: Transoral periosteal thyroidectomy could be feasible and safe.
