    Abstract

    Functional upper airways obstruction is caused by vocal cord dysfunction and classically occurs in paroxysms closely resembling acute asthmatic attacks. We present two cases in which the symptoms and signs of the vocal cord dysfunction demonstrate very little variability with time. We suggest that as part of this disorder, a syndrome of chronic unremitting symptoms may occur.
