The objective of this research is to perform a pilot study on patients undergoing laryngoscopy for diagnostic and tumor staging purposes (for pharyngeal or laryngeal cancer) in which intraoperative CT imaging will be performed both prior to (but after induction of general endotracheal anesthesia) and during placement of the laryngoscope in order to better understand anatomic changes that occur during instrumentation of the oral cavity and oropharynx. The goals of the study are: 1. Develop a suite of de-identified images and surface renderings that qualitatively show how a tumor and the upper aerodigestive tract anatomy deform during a laryngoscopic evaluation. 2. Create deformation models of the upper aerodigestive tract. This data to be used for future retractor development as well as for virtual image guided surgery.
