Retropharyngeal abscess: clinical review.

Retropharyngeal abscess, once a relatively common entity in children, is uncommon today. From 1981 to 1991, we treated 20 cases. Abscesses secondary to upper respiratory infection in children were seen only in three (15%) cases. Trauma and foreign bodies were the most common etiologic factors in the adult subgroup. Streptococcus viridans and Klebsiella pneumoniae were the most common pathogens. The use of contrast-enhanced computed tomography has had a significant impact on the diagnostic work-up. The choice of initial antibiotic therapy is discussed. There were no deaths in this series.
