Résumé
Peritonsillar abscess (PTA) is a common infectious disease, requiring urgent management by an ENT specialist. The conditions for outpatient versus inpatient management, needle aspiration only or surgery are not clearly codified. The results of this study will guide to better understand the clinical, radiological and biological factors to be considered to estimate the good or bad evolution of patients with PTA and thus obtain a personalized care plan. Material and methods: retrospective bicentric study on 670 patients, without age limitation. For each patient, all sociodemographic, clinical, biological and imaging data during their stay were collected, for a total of 82 variables. The main endpoint was composite: poor outcome (intensive care unit, or surgery, or new needle aspiration, or prolonged hospitalization). Results: in the adult population, outpatient management can be proposed for an abscess of upper localization, aspiration of more than 33% of its volume and/or having a volume <6 cm3. Other cases are referred to inpatient. Conclusion: the dimensions measured by scanner as well as the quantity of aspiration volume of a PTA guide to choose between outpatient or inpatient.
