REVISIÓN SISTEMÁTICA SOBRE LA INFLUENCIA DE LA EDAD, EL GÉNERO Y LAS VARIACIONES ESTACIONALES EN EL ABSCESO PERIAMIGDALINO.

Introduction and objective: Peritonsillar abscess (PA) is the most frequent complication of acute tonsillitis. Given the discrepancies observed in the literature, we present a systematic review to analyse the prevalence of PA in our setting in relation to three epidemiological factors: age, gender, and climatology. Methods: A literature search was carried out on the influence of age, gender, and seasonality on PA. The databases used were PubMed, Cochrane, and Medline, without time restriction, following the PRISMA methodology. The registry was carried out by three independent reviewers during the month of October 2022. Results: After excluding duplicates, 289 articles were obtained, of which, after the screening detailed in the methodology, we selected 23 as part of the systematic review. Discussion: In most of the included papers, a predominance of PA in men is observed, with a male/female ratio varying from 1.16 to 3. The mean age of onset of PA varies, depending on the study, from 22 to 39 years. Although with disparate results, AP does not seem to have a seasonal predominance, without being able to rule out a certain climatic influence. Conclusions: AP is the most frequent complication of acute tonsillitis. In adults, it predominates in men. The mean age ranges between 22 and 39 years. It does not seem to show climatic preference.
