ObjectiveTo examine preliminary observations that the incidence of adult acute epiglottitis has risen between 1986 and 2000.Materials And MethodsDemographics, annual and seasonal occurrences, clinical presentation, diagnostic procedures, treatment, airway management, and complications of 116 consecutive adult patients with laryngoscopically confirmed acute epiglottitis are presented.ResultsThe mean annual incidence of acute epiglottitis per 100,000 adults significantly increased from 0.88 (from 1986-1990) to 2.1 (from 1991-1995) and to 3.1 (from 1996-2000) (P <.001). This rise seems to be unrelated to Haemophilus influenzae type b infection but related to miscellaneous pathogenic bacteria. During these periods, the number of epiglottic abscesses increased concomitantly with the rise in the incidence of acute epiglottitis (from 4/14 episodes [29%], to 8/38 [21%], and to 16/66 [24%], respectively), showing a relatively constant ratio between both phenomena (P =.843). Twenty-five patients (21%) underwent airway intervention, 16 because of objective respiratory distress and 9 because of imminent respiratory obstruction. Stepwise logistic regression showed that drooling, diabetes mellitus, rapid onset of symptoms, and abscess formation were associated with airway obstruction. Diverse origins for the epiglottic abscess, either from coalescent epiglottic infection or from mucopyocele of the tongue base, are suggested.ConclusionsA rise in the incidence of acute epiglottitis and a concomitant rise in the number of epiglottic abscesses were established. Although the course of acute epiglottitis is often benign and can be safely treated with a conservative management approach, delayed airway obstruction may develop from a few hours to days after admission.
