A multicentre observational study of paediatric head and neck abscesses.

In winter of 2022/3 paediatric ENT surgeons across the UK observed that the incidence of severe abscesses in the head and neck and associated complications was higher than seen in previous years. We aimed to collate and evaluate data from across the UK to establish if this was a true rise in cases, and to describe the factors associated. A multicentre retrospective data collection was undertaken from 13 units across the UK. Patients admitted between September 2022-February 2023 with a head and neck abscess including sinogenic, otogenic, deep and superficial neck abscesses were included. Demographic, disease specific, management and outcome data were collected. Hospital episode statistic data were also requested and analysed to allow for comparison with previous 10 years of head and neck abscesses. 262 patients with abscesses of the head and neck were admitted during the study period, 100 between September and November and 163 between December and February. Mastoid abscesses were the most common abscess across both groups. The rate of group A streptococcus + culture results rose significantly from 12 % in autumn group to 30 % in winter (p = 0.02). The rate of intracranial complications rose from 10 % to 18 % (p = 0.11) and the rate of venous thrombosis rose over the same timeframe from 3 % to 14 % (p = 0.01). This study demonstrated a statistically significant rise in the rate of group A streptococcus associated abscesses when comparing Autumn and Winter 2022/2023. Over the same timeframe a statistically significant rise in the proportion of patients with venous thromboses associated with H&N abscesses was noted. Interestingly, despite perceived national consensus regarding a spike in abscess incidence, the number of abscesses seen in winter 2022/2023 was in keeping with expected rates of paediatric H&N abscesses, based on pre covid year-on-year rise in incidence.
