Acute epiglottitis is one of the most common conditions of the upper airway obstruction in children. The clinical course is not only fulminant but possibly fatal, resulting from massive swelling of the supraglottic structures especially epiglottis caused by Hemophilus influenzae. This is the reason why early recognition and careful airway management are always desired. Numerous reports in the literature reveal that a majority of cases occur mainly in young children under six years of age, however, the recent reports about acute epiglottitis in adults are increasing. We present eight cases of acute epiglottitis in adults with review of the literatures in terms of causative organism clinical feature, diagnosis and management. We also discuss the differences between acute epiglottitis in adults and in children.
