Defining Surgical Criteria for Empty Nose Syndrome: Validation of the Office-Based Cotton Test and Clinical Interpretability of the Validated Empty Nose Syndrome 6-Item Questionnaire

摘要

Objectives/Hypothesis: The validated Empty Nose Syndrome 6-Item Questionnaire (ENS6Q) identifies empty nose syndrome (ENS) patients. The unvalidated cotton test assesses improvement in ENS-related symptoms. By first validating the cotton test using the ENS6Q, we define the minimal clinically important difference (MCID) score for the ENS6Q.
