Although the ESS demonstrates high test-retest reliability, it may not adequately assess different dimensions of nosebleed severity. Additional correlated survey questions and sub-scores may be needed to increase internal consistency to accurately measure each component of epistaxis severity. It is necessary to acknowledge epistaxis severity from different dimensions and to consider evaluating individual ESS items separately for a comprehensive understanding.
