Comparison of ENLYT®, a Portable Flexible Nasopharyngoscope, with the Standard of Care Nasopharyngoscope.

ObjectivesThis study seeks to compare a newly developed portable flexible nasopharyngoscope (ENLYT®) to the standard of care (SOC) flexible nasopharyngoscope.MethodsSubjects were consented to undergo a nasopharyngeal scope exam using ENLYT® after SOC nasopharyngoscope examination. Data collection included a physician feedback survey consisting of questions regarding ease of use, video quality and perceived patient pain. Additionally, subjects provided a comparison of discomfort between the two scopes.ResultsThe following results were compiled from nine examiners completing ENLYT® exams on 50 patients. The nine examiners consisted of five attendings, three residents, and 1 physician assistant. The attendings performed 31 exams (62%) and the others performed 19 exams (38%). 72% of the exam surveys reported the ENLYT® flexible nasopharyngoscope was the same or easier to use than the SOC nasopharyngoscope. 88% of exams reported the ENLYT® video quality was "the same" to "better". 94% of exams reported the perceived patient pain with the ENLYT® flexible nasopharyngoscope was the same or less than the SOC nasopharyngoscope. Subjects reported that 88% of the exams were the same or less discomfort with the ENLYT® scope compared to the SOC scope.ConclusionThe portable ENLYT® flexible nasopharyngoscope was able to provide comparable exam results when compared to the SOC nasopharyngoscope.
