[Disproving the myth of "abscess weather" predisposing to peritonsillitis and peritonsillar abscess]

Peritonsillar abscess (PTA) is often seen as a complication 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. A connection 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.

A retrospective 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 a period of 10 years (2012-2021) was performed. Each patient was individually correlated with daily temperature data from the statistical meteorological office of the City of Munich.

A total of 1450 patients were included, 270 patients (18.62%) with peritonsillitis and 1180 patients (81.38%) with PTA. A correlation between the occurrence of peritonsillitis or PTA and major temperature fluctuations could be excluded in this large patient population. Moreover, a similar frequency of peritonsillitis and PTA was seen throughout the year.

The myth of a temperature dependence of the development of peritonsillitis or PTA and a so-called abscess weather could be negated in this study.
