Kim, Jeon, Lee, Kim, and Kim: Deep Neck Abscesses in Children and Adolescents: 10 Year Experience in Two General Hospitals

Abstract

Purpose

The purpose of this study was to review our recent experiences with deep neck abscesses in children and adolescents and to provide helpful information in treatment and diagnosis by comparing them with those in other available literatures.

Methods

Medical records of 36 children and adolescents admitted for deep neck abscess at two hospitals from January 2000 to October 2010 were reviewed retrospectively.

Results

Male to female ratio was 1.4: 1 and the mean age was 6.5 years. Painful neck swelling and fever were the most frequent symptoms in patients under thirteen years of age whereas trismus and headache were frequent symptoms in patients over fourteen years of age. Submandibular space was the most common site of deep neck abscess in patients under thirteen years of age, whereas peritonsillar space was the most common site in patients over fourteen years of age. The results of bacterial cultures were positive in 61.5% of drained cases. Staphylococcus aureus was the most commonly identified bacteria in 6 patients (37.5%) and 5 of them were under 2 years of age. Twenty six patients received surgical drainage while the others were treated with antibiotics only. There were no statistically significant differences in the durations of admission, fever after admission, and antibiotic treatment between surgical and medical treatment groups.

Conclusion

The common sites of deep neck abscess, associated symptoms, and causative organisms were different between children and adolescents. As there were no differences in durations of admission, fever, or antibiotics treatments between surgical and medical treatment groups, surgical drainage may be avoided by early recognition and suspicion. However, if there is no improvement of symptoms or size of abscesses within 48–72 hours of antibiotic treatment, surgical drainage should be considered. (Korean J Pediatr Infect Dis 2011;18:163–172)
