The submandibular gland is responsible for 70% to 90% of unstimulated saliva production. Its excision causes a decrease in basal salivary flow resulting in increased symptoms of subjective xerostomia and decreased quality of life. In this study, we have tried to assess the pattern of nodal metastasis in relation to the submandibular gland. With this study, we have tried to find out whether submandibular gland preservation is a viable option in patients with carcinoma of the oral cavity. ⋯ Involvement of level Ib in early tongue cancers is not very common and direct metastases to the submandibular glands are rare. Even when metastasis is present in level Ib, it can be excised without affecting the submandibular gland. In early tongue lesions, submandibular gland mobilization for dissection at level Ib is not required as no metastases deep to the submandibular glands were seen in these patients. © 2016 Wiley Periodicals, Inc.

Although intraoperative nerve monitoring (IONM) is utilized increasingly, the information on the related anesthesia technique is limited. This study presents an up-to-date clinical algorithm, including setup and troubleshooting of an IONM system, endotracheal tube placement, and anesthetic parameters. To our knowledge, this is the first interdisciplinary collaborative protocol for monitored neck surgery based on the published evidence and clinical experience. ⋯ An IONM system entails an anesthesiologist who understands the challenges posed by this technique; muscle relaxation must be minimized/eliminated to optimize IONM. © 2016 Wiley Periodicals, Inc.

There are no level I studies to guide treatment for resectable oropharyngeal squamous cell carcinoma (SCC). Treatment toxicities influence management recommendations. Ongoing investigations are examining deintensified treatments for human papillomavirus (HPV)-associated oropharyngeal SCC. ⋯ T1 to T2N0M0 resectable oropharyngeal SCC can be treated with surgery or radiation without chemotherapy. Patients with T1-2N1-2aM0 disease can receive radiation, chemoradiation, or transoral surgery with neck dissection and appropriate adjuvant therapy. Patients with T1-2N2b-3M0 disease should receive chemoradiation or transoral surgery with neck dissection and appropriate adjuvant therapy. Concurrent chemoradiation is preferred for T3 to T4 disease. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1299-1309, 2016.

The nasoseptal flap has revolutionized reconstruction of ventral skull base defects. The past decade is also noticeable by the evolution of transoral robotic surgery (TORS). Reconstruction of the oropharyngeal defect is challenging. Good reconstructive options with less cicatricial retraction are desirable and still lacking in the literature. ⋯ The nasoseptal flap has shown to be feasible and reliable for reconstruction of the oropharyngeal defect after TORS. When soft palate resection is warranted, this flap provides excellent coverage. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2495-E2498, 2016.

Comparative Study
Primary surgery for advanced-stage laryngeal cancer: A stage and subsite-specific survival analysis.
Treatment recommendations for advanced-stage laryngeal squamous cell carcinoma (SCC) have evolved significantly over the last 2 decades. ⋯ Patients with advanced-stage laryngeal SCC with T3 and T4a tumors, N0 neck disease, or supraglottic primaries have the greatest chance of survival when treated with primary surgery. © 2016 Wiley Periodicals, Inc.
