Introduction: The aim of this study is to perform a review of the English-language international literature concerning thyroid surgery performed through the transoral vestibular approach, to evaluate its flessibility and safety in terms of complications., Materials and Method: The review was carried out on 17 studies of 17 different Authors. The following variables were taken into consideration: first Author's name, nationality, year of publication, number of cases, hospital stay, conversion rate, type of surgical approach, total number of total thyroidectomies and loboisthmectomies, operative time range, intraoperative blood loss range, number and percentage of complications., Results: 736 procedures were performed: 289 total thyroidectomies and 447 loboisthmectomies. Surgical approach was trivestibular in 15 cases and combined (oro-vestibular) in 2 cases. The operative time varies from 43 minutes for a loboisthmectomy to 345 for a total thyroidectomy. Intraoperative blood loss ranges from 3 to 300 ml. Ten cases were converted into open surgery. The hospital stay varies from 1 to 10 days. Complications were: transient recurrent laryngeal nerve palsy in 34 cases, permanent in 2 cases; transient hypoparathyroidism in 62 cases. One case of postoperative bleeding, 22 postoperative seroma, 20 cases of mental nerve injury, 8 cases of operative wound infection., Conclusions: Transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a new surgical method, the use of which exclusively meets the aesthetic needs of some patients. Its specific complication is the injury of the mental nerves. Further studies, however, seem to be necessary, on numerically broader cases, to ascertain the real validity of the method.

Aim: The aim of the present study is to report our series of incidental thyroid carcinomas in the last 15 years and their follow-up, discussing therapeutics indications and surgical choices., Patients and Methods: We have considered 1793 patients operated on Surgical Sciences Department of "Sapienza" University of Rome from January 1, 2001 to December 31, 2015. The study was conducted on 83 totally thyroidectomized patients with a real incidental thyroid carcinoma, by clinical, laboratory and instrumental controls. Whole-body scan was the most important test in postoperative evaluation., Results: In our series, the incidence of incidental carcinomas was 4.62%. Compared to the total number of cancer patients, the percentage is 21,9%. In 15.66% of cases there was multifocality and in 7.23% also bilaterality. Regarding the histological type, in all cases they were papillary carcinoma. The size of the neoplastic lesions ranged from a minimum of 3 to a maximum of 10 mm. Whole-body scan revealed lymph node metastasis in 57.69% of patients., Discussion: Comparing these data with our previous studies we have seen a significant increase in incidence of incidental thyroid carcinomas over the years. Our therapeutical choice is total thyroidectomy and complection thyroidectomy after lobectomy, because of a relevant percentage of multifocality and/or bilaterality of these tumors. Many Authors on the contrary prefer a more conservative approach invoking the good prognosis of these tumors. The 57.69% of lymph node metastasis at postoperative whole-body scan comfort us in our setting., Conclusion: Incidental thyroid carcinomas are not uncommon. We consider only tumors until 1 cm in diameter. Multifocality and bilaterality are often present such as occult lymph node metastasis. Our therapeutical choice is total thyroidectomy in order to conduct a proper follow-up.
