Peritonsillar abscess (PTA) is often seen as acomplication of acute tonsillitis and is defined as pus retention between the tonsillar capsule and the peritonsillar tissue. The etiology and pathogenesis have not yet been fully elucidated. Aconnection between certain weather conditions and temperature fluctuations and the occurrence of abscesses in the head and neck region has been discussed for years. The question here is whether higher temperature fluctuations are predisposing for the formation of abscesses. Aretrospective evaluation of all patients hospitalized with peritonsillitis or PTA in the Department of Otorhinolaryngology of the Klinikum Rechts der Isar of the Technical University of Munich during aperiod of 10years (2012-2021) was performed. Each patient was individually correlated with daily temperature data from the statistical meteorological office of the City of Munich. Atotal of 1450patients were included, 270patients (18.62%) with peritonsillitis and 1180patients (81.38%) with PTA. Acorrelation between the occurrence of peritonsillitis or PTA and major temperature fluctuations could be excluded in this large patient population. Moreover, asimilar frequency of peritonsillitis and PTA was seen throughout the year. The myth of atemperature dependence of the development of peritonsillitis or PTA and aso-called abscess weather could be negated in this study.
