Y1 - 2018 N1 - T2 - Textbook of Complex General Surgical Oncology AB - Approximately 41,000 cases of head and neck squamous cell carcinoma (HNSCC) are diagnosed annually in the United States, of which approximately one-third arises within the oropharynx.1 Located posterior to the oral cavity and between the nasopharynx and larynx, the oropharynx is critical in maintaining normal speech and swallowing. Its main components include the soft palate, posterior and lateral pharyngeal walls, faucial arches, tonsillar fossa, as well as the base of tongue (which anchors to the hyoid bone at the inferior border of the oropharynx). Its nonrestraining soft tissue boundaries as well as its rich lymphatic supply allow the escape of malignant cells, resulting in the majority of patients presenting with advanced disease (stage III or IV).1 Treatment often consists of surgical resection followed by adjuvant radiotherapy (RT) with or without chemotherapy; however, successful nonsurgical strategies have been developed over recent years through the refinement of RT techniques and/or the use of combination chemoradiotherapy (CRT).2 Recently, however, the introduction of minimally invasive techniques has rekindled interest in surgical therapy.
