The goal of this observational study was to develop effective approaches to introduce first year medical students to gross anatomy/embryology in a compressed time frame. Pedagogical reorganization of anatomy instruction in the regions of Lower Extremity and Head and Neck was based upon core clinical conditions taught in second-year and USMLE Step 1 board review courses. These conditions were not presented as clinical problems, as many students had limited prior training in medical terminology, but focused upon clinical symptoms, allowing for direct correlation of structure and function.

Department of Otorhinolaryngology - Head & Neck Surgery, University of Pennsylvania, Philadelphia, Pennsylvania, U.S.A.

Objectives: Guidelines for transoral robotic surgery (TORS) have generally regarded patients with retropharyngeal carotid arteries as contraindicated for surgery due to a theoretical risk of intraoperative vascular injury and/or perioperative cerebrovascular accident. We aimed to demonstrate that careful TORS-assisted resection and free flap coverage could not only avoid intraoperative injury and provide a physical barrier for vessel coverage but also achieve adequate margin control.

Study Design: Retrospective cohort analysis. Read More

Objectives: With the gradual acceptance of robotic-assisted surgery to treat oesophageal cancer and the application of a single-port approach in several abdominal procedures, we adopted a single-port technique in robotic-assisted minimally invasive oesophagectomy during the abdominal phase for gastric mobilization and abdominal lymph node dissection.

Methods: Robotic-assisted oesophagectomy and mediastinal lymph node dissection in the chest were followed by robotic-assisted gastric mobilization and conduit creation with abdominal lymph node dissection, which were performed via a periumbilicus single incision. The oesophagogastrostomy was accomplished either in the chest (Ivor Lewis procedure) or neck (McKeown procedure) depending on the status of the proximal resection margin. Read More

Esophageal squamous cell carcinoma (ESCC) is the most common secondary tumor in patients with head and neck squamous cell cancer (HNSCC). Currently, endoscopic submucosal dissection (ESD) is the preferred approach to manage superficial ESCC, however, it remains to be elucidated whether patients with HNSCC and early ESCC managed by ESD have different outcomes. We retrospectively analyzed esophageal ESD for early ESCC from September 2009 to September 2017 and the following variables: demographics, tumor and specimen size, Paris classification, location, en bloc and R0 resection rates, overall survival (OS) and adverse events (AEs).

Introduction: Human papilloma virus (HPV)-positive oropharyngeal cancer carries a good prognosis when managed with primary chemoradiotherapy. However, the dramatically increasing rate of this disease means more patients are now developing recurrence, with surgery remaining the mainstay of treatment.

Papillary and follicular thyroid carcinomas arising from the follicular epithelial cells and forming differentiated thyroid cancer (DTC) consist of >95% of thyroid cancers. Lymph node metastasis to the neck is common in DTC, especially in papillary thyroid cancer. The removal of only the metastatic lymph nodes (berry picking) does not help to achieve a potential positive contribution to the survival and recurrence of lymph node dissection in the DTC.

The recurrent laryngeal nerve (RLN) provides motor innervation to the abductor and adductor muscles of the vocal cord, whereas the external branch of the superior laryngeal nerve (EBSLN) provides motor innervation to the cricothyroid muscle, which is the tensor muscle of the vocal cord. Both the RLN and the EBSLN are anatomically close to the thyroid and are therefore at risk of injury during thyroidectomy. These 2 laryngeal nerves must be carefully preserved during surgery to ensure that the function of the vocal cord is not impaired. Read More

Introduction: In patients with squamous cell carcinoma of the orofacial area, the presence of cervical metastases represents a single most significant prognostic factor. This fact underlines the importance of thorough examination of the cervical lymph nodes for potential tumor involvement. To verify this, the most common investigative methods are physical examination (PE), sonography (US) and computed tomography (CT), which have also been used to assess the stage of the disease in the patients in our research.

Objective: Repair of cerebrospinal fluid (CSF) leaks of the lateral recess of the sphenoid (LRS) sinus can be challenging to accomplish via an endoscopic transphenoidal approach. The endoscopic transpterygoid approach can improve surgical access to the lateral recess but requires more extensive surgical dissection. We review our experience with LRS CSF leak repair via both techniques to determine whether preoperative radiologic data can help predict the most appropriate surgical approach. Read More

Thyroid follicular dendritic cell sarcoma (FDCS) is an extremely rare malignancy that originates from follicular dendritic cells of the germinal centers and is characterized by the neoplastic proliferation of spindled to ovoid cells. As there have been only five cases reported in the literature until now, the diagnostic and therapeutic information available to clinicians regarding thyroid FDCS is fairly limited. To our knowledge, this is the first case report of thyroid FDCS without a history of Hashimoto's thyroiditis. Read More
