Improving trans-oral surgical outcomes through intra-operative image guidance
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
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
