Assessment for laryngopharyngeal reflux
All patients answered the RSI question independently(8) and underwent 70-degree angled endoscopy to assess
the laryngeal findings utilizing the RFS tool (9). The
recorded endoscopy video was reviewed and scored by two ORL specialists
independently and the main assessor repeated the scoring 8 weeks later.
LPR is diagnosed if patients had an RSI of more than 13 and RFS of more
than 7(8,9). Inter-observer and intra-observer
reliability for RFS score were then analyzed.
