Transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a feasible novel surgical procedure that does not need visible incisions. We describe our initial experience with TOETVA. We recruited 15 patients who were willing to undergo TOETVA. Inclusion criteria were (a) patients who had a neck ultrasound (US) with a estimated thyroid diameter not larger than 10 cm; (b) US estimated gland volume ≤45 mL; (c) nodule size ≤50 mm; (d) a benign tumor, such as a thyroid cyst, single-nodular goiter, or multinodular goiter; (e) follicular neoplasm; (f) papillary microcarcinoma without evidence of metastasis. The procedure is carried out through a three-port technique placed at the oral vestibule, one 10-mm port for 30° endoscope and two additional 5-mm ports for dissecting and coagulating instruments. CO insufflation pressure is set at 6 mmHg. An anterior cervical subplatysmal space is created from the oral vestibule down to the sternal notch, laterally to the sternocleidomastoid muscle. Thyroidectomy is done fully endoscopically using conventional endoscopic instruments and intraoperative neuromonitoring. There were 34% total thyroidectomies and 66% hemithyroidectomies. All TOETVA procedures were performed successfully with no conversions. The mean operative time was 87.6 (59-118) min for lobectomy and 107.6 (99-135) min for bilateral procedure. We observed one case of transient postoperative hypocalcemia. There was no recurrent laryngeal nerve palsy. The cosmetic result was excellent in all patients. This is the first case series of TOETVA in Italy. TOETVA may provide a method for ideal cosmetic results. The results are encouraging, and we are optimistic about the future expansion of its applicability.

Intraoperative neuromonitoring (IONM) has proven effective for intraoperative verification of RLN function in the conventional thyroid surgery. However, no studies have performed a systematic evidence-based assessment of this novel health technology in endoscopic and robotic thyroidectomy. Evidence-based criteria were used in a systematic review of relevant literature for years 2000-2015. Four electronic databases (CENTRAL, MEDLINE, Cochrane and EMBASE) were used to retrieve relevant reports published from January 1, 2000 to September 1, 2016. The search terms included "endoscopic thyroidectomy", "robotic thyroidectomy", "IONM", "continuous IONM (CIONM)", "neural monitoring", "recurrent laryngeal nerve monitoring", and "superior laryngeal monitoring". The following data were retrieved from eligible studies of patients undergoing endoscopic or robotic thyroidectomy: objective of study, design and setting of study, population, intervention examined, quality of data, follow-up and dropout rate, risk of bias, and outcomes assessed. Of 160 studies retrieved, only 9 (5%) studies used IONM. Eight studies reported 522 nerve at risk (NAR) with IONM. Only three were prospective randomized studies. Reports of IONM endoscopic and robotic procedures included their use for re-surgery and use in both benign and malignant cases. None of the IONM endoscopic procedures involved bilateral palsy. Two studies reported the use of a staged strategy. The rates of recurrent laryngeal palsy were 0-3.6% for transient and 0-0.4% for permanent. Only 30% of the studies performed vagus nerve stimulation, and only 25% performed superior laryngeal nerve monitoring. In addition to the use of IONM as an assistive technology for navigating the anatomy in challenging procedures such as endoscopic and robotic thyroidectomy, IONM has potential use as a routine adjunct to the conventional video-assisted nerve identification in thyroidectomy.

This study showed a better prognosis in patients with NEBC compared with breast carcinomas with a minor neuroendocrine component and with conventional invasive ductal or lobular cancers.

The objective is to compare the consequences of routine visualization (RV) and the application of intermitted (I-IONM), standardized (S-IONM), and continuous monitoring (C-IONM) of recurrent laryngeal nerve (RLN) management. RV includes that 698 RLNs managed solely with visual identification. In a second period 777, RLNs were handled by the I-IONM. The third period 768 RLNs monitoring was performed according to the standards. C-IONM via VN stimulation included 626 RLNs. The following issues were analyzed and compared per each period study: RLN identification rate, branching detection, assessment of NRLN, intraoperative recognizable nerve damage, stage thyroidectomy rate, transient or definitive lesions, bilateral nerve palsy, and recovery time. Significance for nerve identification rate was achieved (p = 0.03) when the statistical analysis was applied between RV vs. S-IONM and C-IONM. Extralaryngeal bifurcation was identified in 21, 44, 43, and 46 of RLN dissected, respectively, per period (p = 0.005). The incidence of paralysis in identified and unidentified RLN was 3.8 % (107/2806) and 82 % (52/63), respectively. Rates of temporary/permanent RLNP were 16.7/1.7, 5/1.1, 4.5/1, and 3.1/0 % per period study, respectively (p = 0.07). Recognizable intraoperatively nerve damage was, respectively, 15, 45, 100, and 100 % for period study (p = 0.03). The recovery of injured nerves was significantly faster in C-IONM group. S-IONM and C-IONM cumulate 40-stage procedures. The standardized technique, guidelines adherences, and C-IONM allowed to (1) increase RLN identification; (2) reduce the severity of injuries in terms of (a) reset bilateral RLNP, (b) faster recovery time, and

There are no significant series of patients in worldwide literature to develop standard protocols. Pregnant women must be followed by a multidisciplinary team.

The frequency of neuromonitoring during thyroid surgery is underreported in Italy. The present survey depicts and describes the patterns of use, management, documentation for IONM devices of IONM during thyroid surgery by surgeons in Italy. A point prevalence survey was undertaken. Source data were mixed from Italian surgeons attending the 2014 International Neuromonitoring Study Group (INMSG) meeting, four IONM manufacturers available in Italy and surgical units were identified from Company sales data. Qualitative and quantitative data were used to analyze. Questions probed IONM prevalence, surgeon background, hospital geographic practice locations, type of hospital, rationale for IONM use, sources of initial capital investment for IONM acquisition, type of equipment, use of continuous IONM, monitoring management, use of distinctive standards, and IONM documentation. IONM is currently delivered through 48 units in Italy. In 2013, the distribution of IONM by specialties included: general (50 %), ENT (46 %), and thoracic surgery (4 %). Overall, 12.853 IONM procedures were performed in the period from 2006 to 2013: 253 were performed in 2007 and about 5,100 in 2013. Distribution according to the type of hospital is: public 48 %, academic setting 37 %, and private maintenance 15 %. The use category of high volume thyroid hospitals represented 33 %. Initial capital investment for the acquisition of the monitoring equipment was 67 % public and 33 % with charitable/private funding. Audio plus graphic and EMG electrodes surface endotracheal tube-based monitoring systems accounted for the majority. Continuous IONM was introduced in 5 Academic Centers. Overall motivations expressed are legal (30 %), RLN confirmation (20 %), RLN identification (20 %), prognosis (10 %), helpful in difficult cases (10 %), decrease surgical time (5 %), and educational (5 %). The survey revealed that participants had few experience with the standardized approach of IONM technique (28 %). General IONM information to patients and/or subsequent specific IONM informed consent was initiated in 8 % of centers. EMG determinations were included in medical chart in 20 %. There were no significant associations found between all parameters considered. The present study describes an increased utilization of IONM in Italy. We highlighted areas for improvement in the management and documentation of IONM.
