We defined PhOP as the minimum pressure wherein all areas of the airway were opened. A blinded evaluation of the procedure video was performed by either one of two sleep surgery fellows or an attending sleep surgeon to create a VOTE score for the DISE exam and PhOP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All\n                      <jats:italic>n\u2009=<\/jats:italic>\n                      \u200917 patients enrolled had OSA with a mean AHI of 30.5 and standard deviation 17.8.
