Abstract

Soft-tissue lateral neck radiography is important for diagnosing acute supraglottitis. This study aimed to determine the objective criteria for a diagnosis of acute supraglottitis from soft-tissue lateral neck radiographs in Korean adults. The parameters in 30 adult patients with acute supraglottitis were compared with those of age- and sex-matched normal 30 Korean adults. The mean of epiglottis width (EW) and aryepiglottic fold width (AEW) in the control group were 4.37 ± 0.93 mm, 2.45 ± 0.71 mm, respectively and in the patient group they were 15.87 ± 3.60 mm, 6.4 ± 2.55 mm, respectively. The sensitivity and specificity of an EW greater than 7mm were 100%, and 100% respectively. The sensitivity and specificity of an AEW greater than 4.5 mm were 83%, and 100% respectively.

Keywords: Supraglottitis, epiglottis width, aryepiglottic fold width, parameter
