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

Abstract

Objectives

This study seeks to compare a newly developed portable flexible nasopharyngoscope (ENLYT^®) to the standard of care (SOC) flexible nasopharyngoscope.

Methods

Subjects 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.

Results

The 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.

Conclusion

The portable ENLYT^® flexible nasopharyngoscope was able to provide comparable exam results when compared to the SOC nasopharyngoscope.
