Abstract
OBJECTIVE: To investigate the incidence of acute epiglottitis (AE) and the clinical features of patients with AE complicated by peritonsillar abscess (PTA), considering that PTA, especially inferior-type PTA, is often a comorbidity of AE. METHODS: We retrospectively reviewed the medical records of patients who were diagnosed as having AE by otolaryngologists and referred to our hospital between January 2009 and December 2017. All the patients underwent laryngeal endoscopy and contrast-enhanced computed tomography (CT) for examination of the severity of AE and its complications by other infections, including PTA. The clinical characteristics of patients with PTA were compared with those of patients without PTA. RESULTS: A total of 139 patients were enrolled, of whom 21 (15%) were found to have PTA. Among the 21 patients, only one had a superior-type PTA and the others had an inferior-type PTA. The patients with complicated AE by an inferior Cap-type PTA frequently showed unilateral arytenoid swelling. CONCLUSION: PTA is a comorbidity of AE, and unilateral arytenoid swelling is considered to suggest the presence of inferior-type PTA.
