About the study

This study aims to demonstrate that a polymer retractor functions the same as a standard metal retractor used during endoscopy and throat surgery. The retractor is the device that holds the mouth open so the surgeon can easily access the mouth and throat. For example, this study aims to confirm that the mouth is held open the same amount with a polymer retractor as it is with a metal retractor. Benchtop experiments have demonstrated that the metal and polymer retractor's function the same, and thus this study will use this in patients.
