Abstract
BACKGROUND Totally laparoscopic distal gastrectomy gained wide popularity in recent years. Laparoscopic total gastrectomy with intracorporeal esophagojejunostomy (LTGIE) is much less performed. In this study, we reported our preliminary experience of LTGIE using the transorally inserted anvil (OrVil). METHODS Clinical data of patients with upper gastric cancer who underwent LTGIE from January 2016 to January 2017 were retrospectively collected. The operative time, intraoperative blood loss, postoperative recovery time of intestinal function, the length of hospitalization and postoperative complications were summarized and compared between early and later cases. RESULTS There were totally 26 patients underwent LTGIE using OrVil successfully. The mean total operation time and esophagojejunostomy time was 272.8 min and 45.3 min. The mean estimated blood loss was 113.8 ml. The mean first flatus time was 3.1±0.9 days and the postoperative length of hospitalization (LOH) was 13.0±6.4 days. Three patients suffered postoperative complications, including one abdominal fluid collection, one pulmonary embolism and one pulmonary infection. During the follow-up period, neither local recurrence nor anastomosis-related morbidity was observed. CONCLUSIONS The LTGIE using OrVil is feasible and safe for upper gastric cancer. These preliminary results warrant further evaluation in a larger population to validate.

Abstract
Remote-access approaches to the thyroid gland have seen a rapid evolution recently with the development of various techniques to minimize the cosmetic and quality-of-life impact of a visible scar. Most approaches have required significantly more tissue dissection and have been limited in their extent to treat contralateral disease. The transoral approach is the most recent iteration of "scarless" thyroidectomy and offers various advantages over other techniques including less tissue dissection, equal access to both sides of the neck, and a superb midline view of the anatomy. Transoral thyroidectomy may be performed with either laparoscopic or robotic technology, each with various advantages and disadvantages. Herein, we discuss our experience with transoral robotic thyroidectomy (TORT).

Abstract
Recently, natural orifice transluminal endoscopic surgery (NOTES) has been applied in thyroid surgery with transoral access. The benefit of transoral endoscopic thyroidectomy is the potential for scar-free surgery. However, there are many concerns over some aspects, such as infection, recurrent laryngeal nerve injury, and oncological outcome. In this paper, we have reviewed the development history and the current clinical evidence of this innovative surgery. We conclude that the transoral endoscopic thyroidectomy vestibular approach (TOETVA) is feasible and can be considered no longer an experimental operation.

Abstract
The authors report the case of a 5-year-old boy in whom extraneural metastases developed 5 years after he underwent an occipitocervical fusion and transoral approach to treat a clival chordoma without local recurrence. Following primary resection, the patient's postoperative course was complicated by recurrent meningitis secondary to CSF leak, which responded to antibiotics, and communicating hydrocephalus, for which a ventriculoperitoneal shunt was placed. The patient then underwent postoperative proton beam radiotherapy. Five years following his initial presentation, surveillance imaging revealed a new asymptomatic lung mass for which the patient underwent thoracotomy and resection of the mass. Histological examination of the lung mass revealed findings consistent with a de-differentiated chordoma, confirming extraneural metastasis from the original tumor without evidence of local recurrence. Chest wall and scalp metastases subsequently developed, and the patient was started on an adjuvant chemotherapy regimen that included imatinib and rapamycin followed by subsequent nivolumab and an EZH2 inhibitor for recurrent, disseminated disease. Despite this patient's remote and distant metastases, primary gross-total resection for chordoma remains a critical treatment objective, followed by proton beam radiotherapy. This case illustrates the importance of interval posttreatment imaging and the emerging potential to treat chordoma with molecularly targeted therapies.

Abstract
The bilateral sagittal split mandibular osteotomy (BSSMO), a common maxillofacial technique for expanding the oropharynx during treatment of micrognathia, is a rarely employed but useful adjunct to improve surgical access to the ventral cervical spine in children. Specifically, it provides enhanced exposure of the craniocervical junction in the context of midface hypoplasia, and of the subaxial cervical spine in children with severe kyphosis. The authors describe their technique for BSSMO and evaluate long-term outcomes in patients. The pediatric neurosurgical database at a single center was queried to identify children who underwent BSSMO as an adjunct to cervical spine surgery over a 22-year study period (1993-2015). The authors retrospectively reviewed clinical and radiographic data in all patients. The authors identified 5 children (mean age 5.3 ± 3.1 years, range 2.1-10.0 years) who underwent BSSMO during cervical spine surgery. The mean clinical follow-up was 3.0 ± 1.9 years. In 4 children, BSSMO was used to increase the size of the oropharynx and facilitate transoral resection of the odontoid and anterior decompression of the craniocervical junction. In 1 patient with subaxial kyphosis and chin-on-chest deformity, BSSMO was used to elevate the chin, improve anterior exposure of the subaxial cervical spine, and facilitate cervical corpectomy. Careful attention to neurovascular structures, including the inferior alveolar nerve, lingual nerve, and mental branch of the inferior alveolar artery, as well as minimizing tongue manipulation and compression, are critical to complication avoidance. The BSSMO is a rarely used but extremely versatile technique that significantly enhances anterior exposure of the craniocervical junction and subaxial cervical spine in children in whom adequate visualization of critical structures is not otherwise possible.

Abstract
OBJECTIVES/HYPOTHESIS To assess the long-term results after transoral submandibulotomy for stones located in the deep hilar and intraparenchymal submandibular region. STUDY DESIGN Retrospective cohort analysis. METHODS Retrospective evaluation including all patients treated with transoral submandibulotomy for sialolithiasis at a tertiary referral center. RESULTS Complete stone removal at the first transoral surgical treatment was achieved in 185 of 234 patients (79.1%). One hundred seventy-five of the 234 patients were followed up for a mean of 31.2 ( ± 20.5) months. During the follow-up period, 140 of the 175 patients (80.0%) became symptom free after one operation. In patients with residual symptoms, no further treatment was needed in 12 patients (6.9%) due to the mildness of the symptoms; 23 patients (13.1%) received further therapy, which was successful in 15 cases. Submandibulectomy only had to be performed in 3.4% of the patients with follow-up (6/175). In a questionnaire survey, 91.4% of the patients stated that they would be prepared to have the same operation again. CONCLUSIONS These findings show that transoral removal of submandibular sialoliths located in the deep hilum or adjacent intraglandular parenchyma is an effective treatment that can be assisted by additional measures. The techniques described show high success rates, good long-term results, low complication rates, and they avoided the need for submandibulectomy in >95% of cases. LEVEL OF EVIDENCE 4.

Abstract
BACKGROUND Transoral endoscopic thyroidectomy vestibular approach (TOETVA) provides excellent cosmetic results from its potential for scar-free operation. The procedure has been applied successfully for Graves' disease by the authors of this work and compared with the standard open cervical approach to evaluate its safety and outcomes. METHODS From January 2014 to November 2016, a total of 97 patients with Graves' disease were reviewed retrospectively. Open thyroidectomy (OT) and TOETVA were performed in 49 patients and 46 patients, respectively. For TOETVA, a three-port technique through the oral vestibule was utilized. The thyroidectomy was done endoscopically using conventional laparoscopic instruments and an ultrasonic device. Patient demographics and surgical variables, including operative time, blood loss, and complications, were investigated and compared. RESULTS TOETVA was performed successfully in all 45 patients, although conversion to open surgery was deemed necessary in one patient. All patient characteristics for both groups were similar. Operative time was shorter for the OT group compared to the TOETVA group, which totaled 101.97±24.618 and 134.11±31.48 minutes, respectively (P<<0.5). Blood loss was comparable for both groups. The visual analog scale (VAS) pain score for the TOETVA group was significantly lower than for the OT group on day 1 (2.08±1.53 vs. 4.57±1.35), day 2 (0.84±1.12 vs. 2.57±1.08) and day 3 (0.33±0.71 vs. 1.08±1.01) (P<<0.05). Transient recurrent laryngeal nerve (RLN) palsy was found in four and two cases of TOETVA and OT group, respectively. Transient hypocalcemia was found in ten and seven cases of TOETVA and OT group, respectively. No other complications were observed. CONCLUSIONS TOETVA is a feasible and safe treatment for Graves' disease in comparison to the standard open cervical approach. It is considered a viable alternative for patients who have been indicated for surgery with excellent cosmetic results.

Abstract
OBJECTIVES The timing of neck dissection (ND) in relation to transoral robotic surgery (TORS) is controversial. This study identifies local practice patterns and economic and social access disparities during adoption of TORS. STUDY DESIGN We analyzed utilization patterns of TORS and ND using the New York Statewide Planning and Research Cooperative System all-payer administrative database. Statewide head and neck cancer incidence from the Centers for Disease Control and Prevention (Bethesda, MD) was used to control for overall cancer incidence. METHODS Patient demographic, insurer, and institutional information of patients aged ≥ 18 (n = 225) years from 2008 to 2012 were evaluated. Temporal trends were analyzed with Poisson regression models for counts. RESULTS Transoral robotic surgery was used in 386 procedures, and 58.3% involved ND (n = 225). Concurrent ND was most frequent (n = 173), followed by staged TORS then ND (n = 44) and staged ND preceding TORS (n = 8). Caucasians were more likely than Blacks/Hispanics to undergo TORS (P = 0.03). Medicare (26.2%) and Medicaid (2.7%) payers comprised a minority of patients compared to those commercially insured (70.2%). Only 20% of patients received care outside a major urban center, and these patients were more likely to undergo staged procedures, P = 0.02. Staged procedures resulted in higher mean hospital charges (P = 0.02). CONCLUSION Concurrent TORS + ND, the most common practice in New York, is more cost-effective. Patients without commercial insurance, patients in racial minorities, or patients residing outside major urban centers may be targeted to improve care access disparities with respect to minimally invasive TORS technology.

Abstract
Disarticulation resections are required for treatment of variety of pathologies of the jaws. These resections are mostly carried out through extraoral approach, which bear significant postoperative morbidity. The transoral approach may be used for this purpose in benign pathological cases of the mandible to limit the postoperative morbidity of extraoral approach, as it provides sufficient access not only for resection and disarticulation but also for immediate reconstruction. This article shares our experience with transoral approach for resection and disarticulation in a case of kerato cystic odontogenic tumor and simultaneous reconstruction. Excellent cosmetic and functional results were observed in 6-month follow-up.

Abstract
BACKGROUND The improvement of optical enhancement devices, such as narrow band imaging (NBI), has enabled us to visualize lesions that cannot be seen upon macroscopic examination. NBI is useful for detecting subtle lesions, including the primary sites of occult primary cancer. METHODS AND RESULTS We describe 2 cases of tiny tonsillar cancer with positive p16 staining. Case 1 was as an occult primary cancer, and case 2 had a foreign body sensation of the pharynx. With transoral examination using a flexible video-laryngoscope with NBI, we successfully detected tonsillar cancer. These patients were treated with surgery, and the patients are currently alive with no evidence of disease more than 1 year posttreatment. CONCLUSION We detected a small primary lesion in the palatine tonsil through transoral examination with NBI, which is a simple and noninvasive method. This approach may be useful to detect subtle lesions, especially in patients with human papillomavirus (HPV)-related tonsillar cancer. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2421-E2424, 2016.

Abstract
OBJECTIVES/HYPOTHESIS To determine the sensitivity and specificity for assessing pharyngeal residue, laryngeal penetration, and tracheal aspiration when comparing findings from the Static Endoscopic Evaluation of Swallowing (SEES) with findings from the Videofluoroscopic Swallow Study (VFSS). METHODS Retrospective study at a tertiary academic medical center. Records were reviewed consecutive outpatients who underwent both SEES and VFSS evaluations. Video segments from SEES and VFSS examinations were blindly judged by experienced clinicians on a categorical/ordinal rating form for the absence, quantitative presence, and location of postswallow residue, penetration, and aspiration. Statistical analysis was performed to identify intra- and interrater reliability and correlation between SEES and VFSS findings. RESULTS Thirty-nine patients were identified who met the above inclusion criteria, for a total of 206 video segments. Inter- and intrarater reliability was judged by Cronbach's alpha to be good to excellent. SEES findings revealed statistically significant correlations with VFSS findings (P < 0.001) with the absence, quantitative presence, and location of thin liquid and solid swallow residue, penetration, and aspiration. In addition, SEES was more sensitive to the presence of liquid residue, penetration, and aspiration than VFSS. CONCLUSION SEES is an endoscopic screening procedure that strengthens the clinical swallowing evaluation by documenting the presence or absence of postswallow residue, penetration, and aspiration. Accurate identification of a patient's risk for aspiration helps to direct further workup. It is an expedient, repeatable, and clinical relevant procedure that can be easily incorporated into a clinician's practice. LEVEL OF EVIDENCE 4. Laryngoscope, 126:2291-2294, 2016.

Abstract
Upper cervical chordoma (UCC) is rare condition and poses unique challenges to surgeons. Even though transoral approach is commonly employed, a minimally invasive technique has not been established. We report a 44-year old Malay lady who presented with a 1 month history of insidious onset of progressive neck pain without neurological symptoms. She was diagnosed to have an axial (C2) chordoma. Intralesional resection of the tumour was performed transorally using the Destandau endoscopic system (Storz, Germany). Satisfactory intralesional excision of the tumour was achieved. She had a posterior fixation of C1-C4 prior to that. Her symptoms improved postoperatively and there were no complications noted. She underwent adjuvant radiotherapy to minimize local recurrence. Endoscopic excision of UCC via the transoral approach is a safe option as it provides an excellent magnified view and ease of resection while minimizing the operative morbidity.

Abstract
CONCLUSION It is suggested that transoral complete excision is the ideal treatment for adult vallecular cyst to avoid life-threatening acute airway obstruction and disease recurrence. OBJECTIVE The objective of this study was to review the clinical characteristics and surgical treatment outcomes of vallecular cysts in adults. METHODS A retrospective chart review was performed at Chonnam National University Hwasun Hospital from January 2009 to December 2014. RESULTS Nine patients (≥ 19-years-of-age) with a vallecular cyst were identified. Most of the patients had minimal or no symptoms at diagnosis. The presence of a vallecular cyst was confirmed in all of the patients by fiberoptic laryngoscopy. All of the cases with a vallecular cyst were treated by the transoral surgical procedure. Recurrence of the vallecular cyst was identified in two (22.2%) patients. One patient had been disease-free after the third operation through the transoral approach. Another patient who underwent marsupialization has been observed without surgery. There were no major complications resulting from surgical intervention.

Abstract
BACKGROUND Transoral robotic surgery has been used with increasing frequency for oropharyngeal malignancies. We present the first known case of a transoral robotic-assisted parathyroidectomy. METHODS/RESULTS A 77-year-old woman with primary hyperparathyroidism was suspected of having a parathyroid adenoma. After several nonlocalizing single photon emission CT/CT sestamibi scans, a neck ultrasound revealed a suspicious low level 6 nodule. Surgical excision of this nodule proved to be a reactive lymph node. She then had a dynamic parathyroid protocol MRI and CT, which revealed a small retropharyngeal adenoma candidate. A transoral robotic-assisted surgical approach was utilized to bluntly dissect the retropharyngeal space just above the arytenoids to excise the nodule. After excision, the intraoperative parathyroid hormone (PTH) normalized and surgical pathology confirmed parathyroid adenoma. CONCLUSION Transoral robotic-assisted surgery is a novel technique that can be utilized for resection of a parathyroid adenoma in the retropharyngeal space.

Abstract
Background We reviewed the current literature pertaining to extended endoscopic endonasal approaches to the craniovertebral junction. Methods A systematic literature review was utilized to identify published surgical cases of endoscopic endonasal approaches to the craniovertebral junction. Full-text manuscripts were examined for various measures of surgical indications, patient characteristics, operative technique, and surgical outcomes. Results We identified 71 cases involving endoscopic endonasal approaches for surgical management of a variety of pathologies located within the craniovertebral junction. Patient ages ranged from 3 to 87 years, with 40 females and 31 males. Five patients required tracheostomy, two were reintubated, and all others experienced an average intubation duration of 0.54 days following surgery. Fifty-eight patients (81.7%) underwent an additional posterior decompression or fusion either before or after the endonasal procedure. A complete resection of the pathologic lesion was reported in 57 cases (83.8%), another five were successful biopsies, and four resulted in partial resection. The follow-up time ranged from 0.5 to 57 months. Conclusion Although the transoral approach has been the standard for anterior surgical management for the past several decades, our systematic review illustrates that the extended endoscopic endonasal approach is a safe and effective alternative for most pathologies affecting the craniovertebral junction.

Abstract
BACKGROUND Neurosurgery in areas with restricted space and complicated anatomy can be greatly aided by the virtual reality (VR) technique. The clivus represents one of such challenging surgical areas, but its VR has not been established. The present study aimed to document a VR model of clival anatomy that may be useful in clival surgery. METHODS High resolution CT angiography and MRI were used. The study included a total of 20 patients who did not have any obvious abnormalities detected in the oral, nasal, and clival areas. The images were fused with a Dextroscope. RESULTS In the VR model, the key structures such as the clival bone, basilar artery, brainstem, pituitary gland, and paranasal sinuses were clearly observed. The morphology of the clivus and its spatial relationships with the neighboring structures were also illustrated. Visualization of the clival model can be made flexible from various planes, angles, or orientations. In addition, surgical access to the clivus via the transoral route or transnasal route was simulated in detail. CONCLUSION The simulation of the VR model offers a straightforward, three-dimensional, interactive understanding of the size and shape of the clivus, and its relationships with the surrounding blood vessels and bones. It also demonstrates simulated operational procedures such as opening the surgical window, measuring the exposure distance and angles, and determining the critical boundaries in relation to key structures such as the brainstem and arteries. Digitalized VR modeling appears to be helpful for understanding the anatomy of the clivus and its surgical approaches.

Abstract
OBJECT Metastatic spinal tumors of the atlantoaxial region are quite uncommon, and surgery is challenging. The aim in this study was to evaluate the safety and efficacy of transoral or transpedicular vertebroplasty combined with posterior fixation in C-2 metastatic disease. METHODS The authors collected from a hospital database all cases of C-2 metastatic tumor treated in the period from January 2009 to December 2012. Cases with histologically confirmed metastatic disease were included, but those with epidural tumorous propagation and signs of spinal cord compression were excluded. RESULTS Five patients (3 females, 2 males) with osteolytic C-2 metastasis were eligible for this study. In 3 cases a purely posterior approach was taken to perform a dorsal open C-2 biopsy and transpedicular vertebroplasty followed by posterior occipitocervical fixation. In the other 2 cases a transoral C-2 biopsy and vertebroplasty were performed in combination with dorsal occipitocervical fixation during the same operative session. Patients were followed up with regular fluoroscopy, MRI, and CT studies as well as neurological examinations. During an average follow-up of 13 months (range 8-19 months), no surgical or neurological complications were associated with this combined approach. In all cases spinal stability and pain reduction were detected. The average pain score according to the visual analog scale was 3.5 after surgery (range 2-5); before surgery, the average score was 7 (range 6-8). The average volume of polymethylmethacrylate injected was 4 ml. The body and dens of the C-2 vertebra was filled more than 60% for each patient. CONCLUSIONS In this small series, simultaneous intraoperative transoral or transpedicular vertebroplasty and dorsal occipitocervical fixation proved to be a safe and effective treatment for patients with osteolytic C-2 metastatic tumors. These techniques may provide excellent pain relief and improvements in quality of life. The true value of these combined techniques should be evaluated in larger series.

Abstract
BACKGROUND Eagle syndrome is often considered in the work-up of odynophagia and neck pain. Classically, this is manifested by ossification or calcification of the stylohyoid ligament or styloid process. There are no reported cases of stylopharyngeal calcification leading to these symptoms. CASE We describe a patient with a suspected submucosal pharyngeal foreign body who was found to have a calcified stylopharyngeus muscle and tendon during surgery. The patient experienced full resolution of symptoms after transoral robotic resection. This diagnosis was initially missed because the radiology was inconsistent with Eagle syndrome. CONCLUSION This is the first report of isolated stylopharyngeal calcification, and this unique manifestation of a stylohyoid complex syndrome should be considered in patients with symptoms of Eagle syndrome without styloid elongation.

Abstract
The growing practice of endoscopic surgery has changed the therapeutic management of selected head and neck cancers. Although a negative surgical margin in resection of neoplasm is the most important surgical principle in oncologic surgery, controversies exist regarding assessment and interpretation of the status of margin resection. The aim of this review was to summarize the literature considering the assessment and feasibility of negative margins in transoral laser microsurgery (TLM) and transoral robotic surgery (TORS). Free margin status is being approached differently in vocal cord cancer (1-2 mm) compared with other sites in the upper aerodigestive tract (2-5 mm). Exposure, orientation of the pathological specimen, and co-operation with the pathologist are crucial principles needed to be followed in transoral surgery. Piecemeal resection to better expose deep tumor involvement and biopsies taken from surgical margins surrounding site of resection can improve margin assessment. High rates of negative surgical margins can be achieved with TLM and TORS. Adjuvant treatment decision should take into consideration also the surgeon's judgment with regard to the completeness of tumor resection.

Abstract
Transoral laser microsurgery (TLM) was pioneered in the early 1970s as an approach to treat laryngeal pathology with precision and minimal thermal damage to the vocal cords. Over the last four decades, TLM has become an integral part of the treatment paradigm for patients with laryngeal cancer. TLM is one of the primary treatment options for early-stage laryngeal tumors. However, in recent years, surgeons have begun to develop TLM into a more versatile approach which can be used to address advanced laryngeal tumors. Although functional outcomes following TLM for advanced laryngeal disease are scarce, survival outcomes appear to be comparable with those reported for organ preservation strategies employing external beam radiation therapy (EBRT) and chemotherapy. In addition, TLM plays an important role in the setting of recurrent laryngeal cancer following primary irradiation. TLM has been demonstrated to decrease the need for salvage total laryngectomy resulting in improved functionality while retaining comparable oncologic outcomes. The aim of this review is to elucidate the indications, techniques, and oncological outcomes of TLM for advanced laryngeal cancers.

Abstract
We present a case of submandibular duct calculi diagnosed using transoral sonography. Sonography is the first-line imaging modality of salivary gland calculi. However, it is performed via a transcutaneous approach, which is limited in identifying small salivary duct calculi. Using an intraoral transducer, transoral sonography can visualize the submandibular duct and detect the presence of small calculi, thus overcoming the limitations of transcutaneous sonography.

Abstract
Pathologic fractures involving the C2 vertebral body and odontoid process pose a unique dilemma, as the surgical approach for direct odontoid process screw fixation has several limitations. There have been a small number of transoral approach C2 vertebroplasty or kyphoplasty reported in the literature. Previous attempts were performed utilizing fluoroscopy or CT guidance. We report a case of a fluoroscopically guided transor-al approach vertebroplasty in a patient with a lytic lesion involving the C2 vertebral body, extending into the odontoid process with an underlying pathologic fracture. This case is unique as two separate punctures were required in order to adequately stabilize the pathologic fracture, CTA was performed preoperatively to better evaluate regional vasculature, and a post-procedure rotational flat panel CT was performed to assess cement placement.

Abstract
BACKGROUND The purpose of this study was to report the treatment outcomes of patients with advanced oropharyngeal cancer treated with transoral laser microsurgery (TLM) followed by radiation therapy (RT) at Mayo Clinic in Arizona. METHODS A retrospective study of 80 patients treated from January 1, 2000 to November 7, 2011 was performed. All patients had stage III/IV oropharyngeal tumors and underwent TLM with neck dissection. Adjuvant RT was then given. Thirty-seven patients received concurrent adjuvant chemotherapy. The primary outcome was locoregional control. RESULTS Median follow-up was 47.3 months (range, 9.7-139.2 months). The 3-year locoregional control, recurrence-free survival, and overall survival rates were 98.6% (95% confidence interval [CI], 91% to 100%), 91.1% (95% CI, 81% to 96%), and 93.7% (95% CI, 84% to 98%), respectively. There were a total of 5 treatment failures, 1 regional and 4 distant. Twenty-six patients underwent neck only RT with exclusion of the primary site. CONCLUSION TLM followed by RT for advanced oropharyngeal cancer results in excellent locoregional control rates.
