BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate surgical completeness in endoscopic total thyroidectomy with central neck dissection via unilateral axillo-breast approach (UABA) compared with bilateral axillo-breast (BABA) and open approach (OA) by means of the radioactive iodine uptake (RAIU) ratio and thyroglobulin (Tg) of remnant thyroid. SUBJECTS AND METHOD: From July 2010 to March 2013, 82 patients who had underwent total thyroidectomy with central neck dissection and postoperative radioactive iodine (RAI) ablation for papillary thyroid carcinoma were enrolled. Of these patients, 27 patients underwent UABA, 24 patients BABA, and 31 patients OA. Clinicopathologic data, surgical outcome, stimulated Tg and RAIU ratio on the first postoperative RAI ablation scan were compared among 3 groups. RESULTS: Patients in the endoscopic surgery groups (UABA, BABA) were younger than those in the OA groups. Invasiveness such as operation time, postoperative pain, and drain amount in UABA was less than that in BABA and severer than that in OA. Other variables regarding clinicopathologic and surgical data were not significantly different. Stimulated Tg and RAIU ratio did not show significant differences among 3 groups (p=0.659 and p=0.664). CONCLUSION: The completeness of UABA was comparable with that of BABA and OA. The UABA may be a safe option for patients who need endoscopic thyroidectomy for papillary thyroid carcinoma.

BACKGROUNDWith the development of natural orifice trans-luminal endoscopic surgery, studies on transoral video-assisted thyroidectomy in preclinical experiments (e.g., human anatomy and animal trials) were progressing gradually. From 2009 to 2011, embalmed human cadavers were dissected to define the anatomical location, surgical planes, and related neural and vascular structures to create a safe transoral access to the front cervical spaces. Recently, experimental transoral endoscopic thyroidectomy was performed to verify the feasibility of this approach on 15 fresh specimens.
METHODSFifteen specimens were placed in the supine position with slight neck extension. Endoscopic incision was made on the midline between the Wharton's duct papillae and two other incisions were made on mandibular first premolar buccal mucosa. Sublingual combined bilateral vestibular tunnels were created from oral cavity to the cervical region. The neck subplatysmal working space was insufflated with CO2 at 6-8 mmHg. The bilateral thyroid lobes and central lymph nodes were dissected under craniocaudal view.
RESULTSThree incisions were made in the oral cavity without any incisions on the body surfaces. The distance from the oral cavity to front neck region was the shortest. Bilateral thyroid lobes and central neck region were fully resected via transoral approach. This approach provided a craniocaudal view, in which retrosternal thyroid gland and lymph nodes were easily accessible. The recurrent laryngeal nerve could be identified safely on the inferior cornu of the thyroid cartilage. The only structure at risk was the mental nerve. Camera motion was somewhat limited by the maxillary dentition. The volume of harvested thyroid nodule through sublingual tunnel in the fifteen human cadavers was (40 ± 15) cm(3).
CONCLUSIONThe transoral procedure is progressive and innovative which not only gives the best cosmetic result and minimal access trauma but also provides a craniocaudal view.
