Acute epiglottitis is an inflammatory process of the supraglottic region, which involving the epiglottis and hypopharynx region. This disease can be recognized easily radiologically and virtually all death are preventable. The lateral neck radiograph with soft tissue technique is of critical value when the diagnosis is in doubt and usually characteristic when compared to the normal. Authors reviewed available neck radiograph of 92 cases among the 95 cases of clinically confirmed adult epiglottitis during 4 years in wallace Memorial Hospital. The results are as follows; 1. Male to female sex ratio was 13:2. 2. The most common age group was 4th decade. 3. The most common clinical symptoms are sorethroat (87%) and dysphagia (87%). 4. The radiologic findings are swelling of epiglottis, arytenoid and aryepiglottic folds in all cases. Other findings are ballooning of hypopharynx (92%), vallecular narrowing or obliteration (92%), uvula swelling (33%), narrowing of airway adjacent to epiglottis (17%), swelling of prevertebral soft tissue (8%).
