Impact of the COVID‐19 era on clinical presentation, management and microbiology in paediatric peritonsillar abscess: A case–control study

Abstract

ObjectivesPeritonsillar abscess (PTA) is the most common soft‐tissue infection of the head and neck. This potential complication of tonsillitis has demonstrated unique microbial trends during the COVID‐19 pandemic. This era has resulted in a major shift in the hygiene and social habits of the general population, which has resulted in changes in the presentation, management and microbiology of several infectious diseases. To date, the impact of COVID 19 on PTA microbiology and clinical presentation in the paediatric population has yet to be investigated.DesignRetrospective chart review comparing all cases of paediatric (age 0–18) PTA in an academic tertiary centre during the COVID‐19 pandemic (03/2020–02/2022) and compared them to two control groups: pre‐COVID (03/2018–02/2020) and post‐COVID (03/2022–03/2023). All patients were treated with either needle aspiration, incision and drainage or both means in addition to intravenous antibiotics.SettingA large Ear Nose and Throat department in a tertiary referral center.ParticipantsConsecutive children aged 18 years or under, admitted with a diagnosis of Peritonsillar abscess.Main Outcome MeasuresWe analyzed the clinical and microbiologcal features of all cases of pediatric peritonsillar abscess during the COVID‐19 era (03/2020‐02/2022) and compared them to a pre and post control cases.ResultsA total of 96 PTA cases were included (35 pre‐COVID, 35 COVID and 26 post‐COVID). The means of procedural treatment shifted in favour of incision and drainage versus needle aspiration during the COVID era. The length of hospitalisation increased during the COVID era (3.6 days vs. 2.1 and 3.1 pre and post‐COVID respectively, p < .001). No other notable differences in the clinical and demographic features were found between the three eras. The COVID‐19 era saw an increase in Fusobacterium (37.1% vs. 8.6% and 24% pre and post‐COVID, respectively; p = .008) and Streptococcus Anginosus (31.4% vs. 5.7% and 7.7% pre and post‐COVID, respectively; p = .007) species isolation.ConclusionsThe COVID‐19 pandemic did not seem to impact the clinical presentation of paediatric PTA yet resulted in a change in microbiological pathogens. The choice of I&D as a means to shorten hospital stay during the pandemic may have led to an actual increase in hospital stay, suggesting that NA may be the preferred management approach.

Diagnostic possibilities in peritonsillar abscess and the significance of transcutaneous ultrasound - Systematic Review of the Literature

“…[10] A nd even though COVID-19 introduced significant disruptions to the diagnosis of respiratory system diseases, the clinical presentation of peritonsillar abscess (PTA) seems unaffected by the pandemic. [11] Relying solely on physical examination yields a sensitivity of around 75% and a specificity of 50% in the diagnosis of peritonsillar abscess (PTA). [12] The utilization of artificial intelligence has the potential to enhance their usefulness, as demonstrated by the top-performing algorithm, the artificial neural network, which achieved an accuracy of 72.3%.…”
