Area of Science:

  • Otolaryngology
  • Infectious Diseases
  • Pediatric Medicine

Background:

  • Retropharyngeal abscess (RPA) is a rare deep neck infection.
  • Historically prevalent in young children, recent trends suggest a shift in demographics.

Purpose of the Study:

  • To analyze the changing clinical trends and microbiology of retropharyngeal abscess.
  • To evaluate predisposing factors, causative organisms, and treatment outcomes over a decade.

Main Methods:

  • Retrospective review of 17 retropharyngeal abscess cases treated over 10 years.
  • Analysis of patient demographics, clinical presentations, predisposing factors, and microbiological data.

Main Results:

  • A demographic shift was observed, with 58% of cases in older children and adults, compared to 41% in children under 6.

  • Upper respiratory tract infection (URTI) was the most common predisposing factor (52%).
  • Other factors included sepsis in younger children and foreign body trauma in older patients. Common pathogens were Klebsiella, Staphylococcus, and Streptococcus.

    • Conclusions:

    • Retropharyngeal abscess epidemiology is evolving, with increased incidence in older age groups.
    • Understanding shifting predisposing factors and microbial patterns is crucial for effective management.
    • This study highlights the need for updated diagnostic and therapeutic approaches for RPA.
