[Increasing incidence of mastoidectomies in children : Result of reduced antibiotic therapy or late COVID-19 sequela?]

Abstract

An increasing number of pediatric patients with mastoiditis and aconsequent increase in mastoidectomy rates was noted in 2022 and 2023. This study aimed to analyze the increase in the number of children presenting with mastoiditis and subsequent mastoidectomy, to assess correlations with prior antibiotic treatment or COVID-19 infection, and to provide an overview of involved pathogens, treatment, and disease course. Aretrospective analysis of all patients with mastoidectomy since 2012 was conducted. Data collected comprised type and duration symptoms, prior antibiotic therapy, diagnostic tests and disease course, causal pathogens, length of hospitalization, and complications. Ahighly significant increase in mastoidectomies in children could be demonstrated from 2022. Neither the pathogens involved nor the course of disease or complications showed differences. An increase in the number of patients with prior outpatient antibiotic therapy could be shown. About ahalf of the patients becoming ill after fall 2022 had apositive history of COVID. Hyperplasia of adenoid tissue was afar less frequent causal mechanism than in the years before COVID. No clear correlation with reduced outpatient antibiotic therapy could be found. Whether there exists an association with prior COVID infection cannot be judged at this time, due to the high number of asymptomatic and therefore unknown COVID infections.
