Randomized Controlled Trial Clinical TrialThe role of computed tomography in the management of peritonsillar abscess.
Twenty-four patients who fulfilled the clinical criteria for peritonsillar abscess (PTA) were randomized into two groups over a 6-month period. Group A (n = 13) underwent CT with contrast, whereas group B (n = 11) was managed without radiologic investigation. In group A, CT with contrast enabled differentiation of PTA from peritonsillar cellulitis in all 13 cases (100%) and demonstrated abscesses in 11 patients (85%), thereby allowing drainage at first attempt. ⋯ In seven patients (64%), pus was found after needle aspiration at first attempt and in one patient after needle aspirations at two locations. In three patients (27%), no pus was found after needle aspirations at three different locations. We conclude that CT enhances diagnostic accuracy, obviating unnecessary drainage procedures, and reduces patient morbidity.
