    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

    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

    No full text
    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

    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

    Immediate postoperative non‐invasive positive pressure ventilation following midface microvascular free flap reconstruction

    Abstract Background There is a rare need for postoperative non‐invasive positive pressure ventilation (NIPPV) following microvascular reconstruction of the head and neck. In midface reconstruction, the free flap vascular pedicle is especially vulnerable to the compressive forces of positive pressure delivery. Case A 60 year old female with Amyotrophic Lateral Sclerosis (ALS) presented with squamous cell carcinoma of the anterior maxilla, for which she underwent infrastructure maxillectomy and fibula free flap reconstruction. To avoid tracheotomy, the patient was extubated postoperatively and transitioned to NIPPV immediately utilizing a full‐face positive pressure mask with a soft and flexible sealing layer. The patient was successfully transitioned to NIPPV immediately after extubation. The free flap exhibited no signs of vascular compromise postoperatively, and healed very well. Conclusion Postoperative non‐invasive positive pressure ventilation can be successfully applied following complex microvascular midface reconstruction to avoid tracheotomy in select patients without vascular compromise of the free flap

    Transoral thyroidectomy: Why is it needed?

    Transoral thyroidectomy (TOT) represents reasonably the desirable minimally invasive approach to the gland due to the scarless non-visible incisions, the limited distance between the gland and the access that minimize tissue dissection and respect of the surgical anatomical planes. Patients are routinely selected according to an extensive inclusion criteria: (I) ultrasonographically (US) estimated thyroid diameter not larger than 10 cm; (II) US gland volume \ue2\u89\ua445 mL; (III) nodule size \ue2\u89\ua450 mm; (IV) a benign tumor, such as a thyroid cyst, single-nodular goiter, or multinodular goiter; (V) follicular neoplasm; (VI) papillary microcarcinoma without lymph node metastasis. The operation is realized through median, central approach which allows bilateral exploration of the thyroid gland and central compartment. TOT is succeed both endoscopically adopting ordinary endoscopic equipments or robotically. In detail three ports are placed at the inferior oral vestibule: one 10-mm port for 30\uc2\ub0 endoscope and two 5-mm ports for dissecting, coagulating and neuromonitoring instruments. Low CO2 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 sterncleidomuscles similar to that of conventional thyroidectomy. TOT is now reproducible in selective high volume endocrine centers
