Abstract
In this study, we describe the role of ultrasound in diagnosing pediatric peritonsillar abscesses (PTAs). A retrospective chart review was conducted on 54 children aged 4 to 17 years who had an ultrasound performed for suspected PTA. Based on ultrasound imaging, the patients were classified into 2 groups: PTA-positive (8, 14.8%) and PTA-negative (46, 85.2 %). Trismus was significantly associated with PTA (50% vs. 13%, P =.03). PTA-positive patients were more likely to be given steroids, be admitted, and have extended hospital stays (P =.04,.004, and.002, respectively). The 2 groups had no significant difference in computed tomography (CT) acquisition, surgical intervention, and return visits (P =.92,.17, and.97, respectively). Larger abscesses trended toward surgical treatment (P =.087). Ultrasound is an efficient diagnostic modality for suspected peritonsillar infections in children, with similar clinical outcomes for PTA-positive and PTA-negative groups. © The Author(s) 2024.
