Since its introduction by Smith and Robinson, the anterior approach to the subaxial cervical spine has become one of the standard procedures for numerous cervical spine pathologies, including, but not limited to degenerative disease, trauma, tumor, deformity, and instability. Along with its increasing popularity and improvements in anterior instrumentation techniques, a comprehensive knowledge of the surgical anatomy during the anterior exposure is critical for trainees and experienced spine surgeons alike to minimize the infrequent but potentially devastating risks associated with this approach. Understanding the anatomy and techniques to minimize damage to relevant structures can reduce the risks of developing notable postoperative complications and morbidity.

Fanconi anemia (FA) is a clinically heterogenous and genetically diverse disease with 22 known complementation groups (FA-A to FA-W), resulting from the inability to repair DNA interstrand cross-links. This rare disorder is characterized by congenital defects, bone marrow failure, and cancer predisposition. is the most commonly mutated gene in FA and a variety of mostly private mutations have been documented, including small and large indels and point and splicing variants.

Methods: In 44 patients with node-positive OPX undergoing concurrent chemoradiation, nodal volumes were measured on cone beam CTs from days 1, 10, 20, and 35. Nodal decrease (ND) was based on percent shrinkage from day 1.
Oral cancer patients experience pain at the site of the primary cancer. Patients with metastatic oral cancers report greater pain. Lack of pain identifies patients at low risk of metastasis with sensitivity = 0.

Importance: Limited data exist on performing major oral cavity resections and reconstructions without elective tracheotomy.
Objectives: To describe a group of patients who successfully underwent major microvascular mandibular reconstruction without an elective tracheotomy and to perform a literature review to identify commonalities between our group and the available literature to identify potential common factors that might contribute to the success of this approach.
Design, Setting, And Participants: Case series with retrospective medical chart review of 15 patients who underwent fibula microvascular free flap reconstruction of mandibular defects without tracheotomy between 2000 and 2014 (the most common indication was osteoradionecrosis) conducted at a tertiary referral hospital center.
Individual bacteria and shifts in the composition of the microbiome have been associated with human diseases including cancer. To investigate changes in the microbiome associated with oral cancers, we profiled cancers and anatomically matched contralateral normal tissue from the same patient by sequencing 16S rDNA hypervariable region amplicons. In cancer samples from both a discovery and a subsequent confirmation cohort, abundance of Firmicutes (especially Streptococcus) and Actinobacteria (especially Rothia) was significantly decreased relative to contralateral normal samples from the same patient.

Study Design: Case report and literature review.
Methods: Case report and literature review.
The vertical rectus abdominus myocutaneous (VRAM) flap is a valuable option for tongue reconstruction. However, the traditional inset (skin to remaining oral mucosa) obviates a more anatomic reconstruction. Eight patients underwent total or subtotal glossectomy with VRAM reconstruction.

Materials And Methods: Surgical procedures were performed on five fresh frozen adult cadavers (ten sides) with no known pathology. Facial transfacial approaches with and without a mandibulotomy and transtemporal approaches were evaluated.

Objectives: Kaposi sarcoma (KS) is a vascular tumor that can affect the mucosa of the upper aerodigestive tract. Although KS is the most common malignancy in patients with acquired immunodeficiency syndrome, it is rare in immunocompetent persons. We describe an unusual presentation of KS in 2 related individuals and describe our attempts to determine whether oropharyngeal KS is associated with human herpesvirus 8 (HHV-8).

Methods: A population-based cohort study of 53,990 patients (1973-2003) was performed using the National Cancer Institute's Surveillance Epidemiology End Results database.
Background: Histologic diagnosis of mucosal melanoma of the head and neck is difficult, requiring immunohistochemical stains which are less reliable than in cutaneous lesions. PNL-2 is a novel marker that has not been examined in mucosal melanoma.
Methods: Nine formalin-fixed tissue sections of mucosal melanoma were stained with PNL-2, human melanoma black (HMB)-45, Melan-A, S-100, and microphthalmia transcription factor (MITF).

Objective: To review the background, case characteristics, and outcomes of malpractice litigation resulting from surgical injury of the spinal accessory nerve.
Design: Retrospective review of indemnity insurance cases (part 1) and court trials (part 2) between January 1, 1985, and January 1, 2007. In part 1, records of the Medical Liability Mutual Insurance Company identified 41 lawsuits in New York State; part 2 was a review of a national legal database (WestLaw) that identified 81 court trials.

Background: Minimally invasive esophagectomy (MIE) via thoracoscopy and laparoscopy have reduced the morbidity and mortality of total esophagectomy at experienced centers. MIE has not been evaluated in combination with major head and neck surgery, or in the otolaryngology literature.
Methods: Case series of 11 consecutive patients undergoing either open or MIE with an ablative neck procedure.
Bioresorbable implants (meshs and plates) are increasingly used in reconstructive craniofacial and skull base surgery. Usually these implants must be contoured to fit the complex craniofacial anatomy ex vivo; occasionally final contouring is performed in vivo and must be done without damaging surrounding structures (e.g.

Purpose: Since its description in the 1970s, the radial forearm free flap has earned a clearly defined role in the armamentarium of reconstructive head and neck surgery. Three decades later, the donor site remains an intrinsic drawback primarily due to its esthetic impact, although functional morbidity is significant in a minority. These points do not outweigh significant advantages but are occasionally reasons for the choice of alternative flaps.

Although abnormalities of vascular anatomy in the forearm are common, variations of the radial and ulnar arteries are rare. Nevertheless, arterial variants in the forearm may present clinically with neurovascular signs or symptoms. Even when anomalous arteries are not apparent, they may complicate surgery of the forearm and hand, as well as reconstructive surgery that involves the harvest of radial or ulnar artery-based forearm free flaps.

Methods: Forty-nine patients with a history of stage II-IV laryngeal squamous cell carcinoma treated primarily with either chemoradiation or by total laryngectomy with postoperative radiation completed the University of Washington Quality of Life instrument, version 4. Patients were identified on a volunteer basis in an academic university head and neck clinic setting.
Objectives/hypothesis: Head and neck squamous cell carcinoma (HNSCCA) has declined in the United States since the late 1970s. During this time, substantial immigration from other countries has occurred, and the average lifespan has increased. We tested the hypothesis that these trends have altered the HNSCCA patient population.
