Retropharyngeal abscess and stridor in infants

To study the perioperative management strategies in a large group of pediatric patients undergoing surgical therapy for suppurative adenitis of the parapharyngeal and retropharyngeal spaces. Retrospective analysis of all patients treated surgically from January 1, 1989, to December 31, 1998, in a tertiary care pediatric hospital. Charts were reviewed for demographic data, duration and nature of symptoms, radiological workup, surgical approach, complications, duration of medical therapy and antibiotic choice, and bacteriological findings. Computed tomography (CT) results were correlated to surgical findings. A dramatic increase in the incidence of deep neck space infection was seen during the study period; this increase was congruent with the increase in culture-positive group A beta-hemolytic streptococcal abscesses. More than two-thirds of the patients were boys with the peak incidence being in the 3- to 5-year-old group. The duration of symptoms before presentation was less than might be expected, especially in the younger age groups. Seventy of 73 children were treated with a transoral approach. Sixty-eight of 73 were successfully treated with one operative intervention. Irregularity of the abscess wall was found to be a stronger predictor of the presence of pus than the presence of ring enhancement. The current study represents the largest series of pediatric retropharyngeal abscesses in the modern medical literature. Changes in the disease process and in management from the first half of the century to today are reviewed, and recommendations for optimal management presented. The data in this series support a transoral approach to these abscesses unless there is extension lateral to the great vessels.

Retropharyngeal abscess is a rare but serious disease in children. Salmonella species are uncommon causative agents of deep neck infections. We present the clinical course of a 10-year-old boy with a retropharyngeal abscess caused by Salmonella lomita and review 18 previously published cases.
