Transoral robotic-assisted thyroidectomy with central neck dissection: preclinical cadaver feasibility study and proposed surgical technique
Recently, a transoral robotic-assisted technique to access the thyroid gland has been introduced. Despite the advantages this approach may have over other minimally invasive and robotic-assisted techniques, we found that the placement of the camera through the floor of mouth led to restricted freedom of movement. We describe our modification to this technique to overcome this problem. In a study using two fresh human cadavers, the camera port of the da Vinci robot was placed in the midline oral vestibule instead of the floor of the mouth. A transoral thyroidectomy and central neck dissection was successfully performed. Our modification led to an unfettered view of the central neck and allowed for a total thyroidectomy and central neck dissection. Our modification of transoral robotic-assisted thyroidectomy provides superior access to the central compartment of the neck over other robotic-assisted thyroidectomy techniques

Transoral robotic thyroidectomy: lessons learned from an initial consecutive series of 24 patients
Background: Transoral thyroid surgery is an ideal method for minimally invasive thyroidectomy, as there is less flap dissection during the procedure and no postoperative scars. Nonetheless, technical obstacles have precluded the wide dissemination of this procedure. We present the surgical procedures and outcomes of transoral robotic thyroidectomy (TORT). Methods: From September 2012 to June 2016, we performed TORT at Korea University Hospital. We used three intraoral ports and a single axillary port for the system\ue2\u80\u99s four robotic arms. The surgical outcomes were retrospectively reviewed. Results: Twenty-four female patients (mean age 39.6 \uc2\ub1 11.6 years; mean tumor size 1.0 \uc2\ub1 1.3 cm) underwent unilateral thyroid lobectomies with or without ipsilateral central neck dissection. Twenty patients had papillary thyroid carcinomas (PTC), three had benign nodules, and one had a follicular thyroid carcinoma. The mean surgical time was 232 \uc2\ub1 41 min; the mean hospital stay was 3.3 \uc2\ub1 0.8 days. The number of retrieved central lymph nodes in the PTC patients was 4.7 \uc2\ub1 3.2. There were no reports of transient or permanent vocal cord palsy, recurrence, or mortality during the median follow-up period of 16.8 months. Paresthesia of the lower lip and the chin due to mental nerve injury was observed in nine of the first 12 patients (six transient, three permanent), but no further reports of paresthesia were recorded after patient 12, when the locations of the intraoral incisions were modified. Conclusions: TORT is feasible and safe for selected patients after technical refinements, and can be a potential alternative approach for scarless thyroid surgery
The “New” Head and Neck Cancer Patient—Young, Nonsmoker, Nondrinker, and HPV Positive: Evaluation
ObjectiveThe near epidemic rise of the incidence of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas (OPSCC) presents the practitioner with a "new" head and neck cancer patient, vastly different from those with the traditional risk factors who formed the basis of most practitioners' training experience. Accordingly, a thorough and disease-specific evaluation process is necessitated. This article will review the evaluation of the HPV-related cancer patient, including a review of the HPV-positive oropharyngeal cancer epidemic from the surgeon's perspective, evaluation of the primary lesion, evaluation of the neck mass, and role of imaging, to provide a framework for addressing the challenging questions patients may ask.Data sourcesAvailable peer-reviewed literature and practice guidelines.Review methodsAssessment of selected specific topics by authors solicited from the Head and Neck Surgery and Oncology Committee of the American Academy of Otolaryngology-Head and Neck Surgery Foundation and the American Head and Neck Society.Conclusions and implications for practiceThe dramatic rise in OPSSC related to HPV is characterized by a "new" cancer patient who is younger and lacks traditional risk factors. Today's caregiver must be prepared to appropriately evaluate, counsel, and treat these patients with HPV-positive disease with the expectation that traditional treatment algorithms will evolve to maintain or improve current excellent cure rates while lessening treatment related side effects

Necrotizing Sialometaplasia of the Hypopharynx.
Necrotizing sialometaplasia (NSM) is a benign, reactive metaplastic condition of the minor salivary gland tissue typically seen in the setting of injury, chemical or traumatic, and is nonneoplastic and self-limited. The diagnosis may be challenging as it may clinically mimic malignancy. We present the case of a 74-year-old male with a 1 pack per day smoking history for 60 years who presented with a reported 20-pound weight loss, dysphagia, and dysphonia progressing over the course of 6 months and found to have a 3.5-cm hypopharyngeal mass on computed tomography imaging and fiberoptic laryngoscopy. Initial frozen section of the mass was concerning for squamous cell carcinoma in situ, but permanent specimens returned as nondiagnostic. Repeat biopsy established a diagnosis of NSM. Two-month follow-up showed complete resolution of the mass. Clinicians should be aware that NSM may present in unusual locations when considering differential diagnoses for laryngeal masses and evaluating for malignancy
Remote Access Robotic Facelift Thyroidectomy: A Multi-institutional Experience
BACKGROUND: Robotic facelift thyroidectomy (RFT) was developed as a new surgical approach to the thyroid gland using a remote incision site. Early favorable results led to this confirmatory multi-institutional experience.
METHODS: Prospectively collected data on consecutive patients undergoing RFT in five North American academic endocrine surgical practices were compiled. Surgical indications, operative times, final pathology, nodule size, complications, and postoperative management (drain use and length of hospital stay) were evaluated.
RESULTS: A total of 102 RFT procedures were undertaken in 90 patients. All but one of the patients (98.9 %) were female, and the mean age was 41.9 ± 13.1 years (range 12-69 years). The indication for surgery was nodular disease in 91.2 % of cases; 8.8 % were completion procedures performed for a diagnosis of cancer. The mean size of the largest nodule was 1.9 cm (range 0-5.6 cm). The mean total operative time for a thyroid lobectomy was 162 min (range 82-265 min). No permanent complications occurred. There were 4 cases (3.9 %) of transient recurrent laryngeal nerve weakness, no cases of hypocalcemia, and 3 (2.9 %) hematomas. There were no conversions to an anterior cervical approach. The majority of patients were managed on an outpatient basis (61.8 %) and without a drain (65.7 %).
CONCLUSIONS: RFT is technically feasible and safe in selected patients. RFT can continue to be offered to carefully selected patients as a way to avoid a visible cervical scar. Future prospective studies to compare this novel approach to other remote access approaches are warranted

Practice patterns of virtual surgical planning: Survey of the reconstructive section of the American Head and Neck Society
Virtual surgical planning (VSP), with custom made implants and guides represents a recent major advance. Nonetheless, knowledge related to practice patterns is limited. The purpose of this study was to provide data from the AHNS Reconstruction Section related to practice patterns, perceived value of VSP, as well as elucidate specific situations which represent high value for the application of VSP.
A multi-center web-based survey consisting of 30 questions regarding practice patterns related to VSP practices delivered via email to 203 members of the AHNS Reconstructive Surgery Section at institutions across North America.
There was a 34% response rate (70/203). A majority of the respondents (96%) used VSP in approximately 50% of their mandibular reconstruction cases, and in 42% of maxillary cases. 46% reported using patient specific implants >75% of cases. Respondents estimated that ~17% of patients received dental implant reconstruction. The majority of respondents (71.0%) did not know the cost of VSP at their institution. The remaining respondents indicated the average cost was $6680 per case. VSP was felt to be necessary as a teaching tool by 55.9%.
Our results demonstrate that a majority of respondents frequently utilize VSP in their practice for head and neck reconstruction. Complex, multi-unit reconstructions were felt to offer the greatest value when utilizing VSP. Future work should focus on increasing the rates of dental implant reconstruction in this population, optimizing value of VSP with careful case selection, and understanding the educational value and costs of these platforms
