Reconstruction of tongue base defects
Introduction
The oropharynx is comprised of four distinct sites 1) soft palate, 2) palatine tonsil/tonsillar fossa, 3) posterior pharyngeal wall, and 4) the base of tongue. The oropharynx is anotomically contiguous with the oral cavity, nasopharynx and hypopharynx. It is a complex anatomical and physiological site that is necessary for degluttation, speech, respiration, and immunological defense. These sites are prone to squamous cell carcinoma in individuals who have a history of extensive tobacco or alcohol use. Squamous cell cancer of the tongue base is one of the most challenging tumors to manage.
