The role of adjuvant systemic corticosteroid in pediatric retropharyngeal and parapharyngeal abscess

Abstract

ObjectivesTo evaluate the potential benefits of systemic corticosteroids as an adjuvant treatment for pediatric retropharyngeal abscess (RPA) and parapharyngeal abscess (PPA). MethodsWe retrospectively reviewed medical records of patients diagnosed with RPA and PPA who were admitted to Shenzhen Children's Hospital between January 2010 and January 2023. Data on demographic characteristics, clinical presentation, physical examination, laboratory data, use of corticosteroids, management, duration of hospital stay, need for surgical drainage, and complications were collected. Patients were divided into two groups: non-corticosteroid group (antibiotic only) and corticosteroid group (corticosteroid and antibiotic). ResultsA total of 111 patients were enrolled. There were 51 cases in non-corticosteroid group and 60 cases in corticosteroid group (10 cases received methylprednisolone and 50 cases received dexamethasone). There was no significant difference in sex, age, location of abscess, size of abscess and laboratory parameters at admission and discharge between the two groups. The surgical drainage rate was significantly lower in the corticosteroid group than in the non-corticosteroid group (p = 0.008). The hospital duration was also shorter in the corticosteroid group than in the non-corticosteroid group (p = 0.026). The hospitalization cost was significantly lower in the corticosteroid group than in the non-corticosteroid group (p = 0.000). ConclusionThe use of systemic corticosteroids along with antibiotics in children with RPA and PPA may reduce the need for surgical drainage, shorten hospital duration, and decrease hospitalization cost. Further studies are needed to confirm these findings and determine the optimal timing, duration, and route of administration of corticosteroids.
