No consensus criteria exist for the diagnosis of ENS and many ENTs will wait a year before diagnosing in hopes the patient accepts the new airflow; it is typically diagnosed by ruling out other conditions, with ENS remaining the likely diagnosis if the signs and symptoms are present. A "cotton test" has been proposed, in which moist cotton is held where a turbinate should be or in various locations in the nasal passages, to see if it provides relief and an airflow pattern that allows for natural breathing; while this has not been validated nor is it widely accepted, it may be useful to identify which people may benefit from surgery. As of 2015, protocols for using rhinomanometry to diagnose ENS and measure response to surgery were under development, as was a standardized clinical instrument (a well defined and validated questionnaire) to obtain more useful reporting of symptoms. A validated ENS-specific, 6-item questionnaire called the<unk>  6-item Questionnaire (ENS6Q) was developed as an adjunct to the standard Sino-Nasal Outcome Test 22 (SNOT-22). The ENS6Q is the first validated, specific, adjunct questionnaire to the SNOT-22. It can more reliably identify patients suspected of ENS. The ENS6Q is gaining usage in studies on ENS. Classification All turbinates removed – Right lateral wall view. Anatomy of the nasal cavity Four types have been proposed: * ENS secondary to inferior turbinate resection * ENS secondary to middle turbinate resection * ENS secondary to both inferior and middle turbinate * ENS after turbinate-sparing procedures
