Defining the role of surgical drainage in paediatric deep neck space infections

Abstract

Objectives

Surgical drainage is the traditional mainstay of treatment of paediatric deep neck space infection (DNSI), but recently non‐operative management in selected cases has been advocated. We sought to identify any characteristics predictive of requirement for surgical intervention.

Design

Retrospective cohort study using receiver‐operating characteristics analyses.

Setting

Tertiary referral paediatric hospital.

Participants

Children (≤16 years) with a radiologically confirmed diagnosis of retro‐ or para‐pharyngeal abscess over a ten‐year period.

Main outcome measures

Predictive value of clinical and radiological variables in determining requirement for surgical intervention. Length of hospital stay (LoS) was also examined.

Results

Ninety‐three children were studied, 15 (16.1%) of whom underwent immediate surgery, 42 (45.2%) of whom underwent delayed surgery following an initial period of conservative management, and 36 (38.7%) of whom were managed conservatively. Age, WCC, and CRP were not predictive of the need for surgical drainage. Radiological abscess diameter, however, was predictive of requirement surgery (AUC=0.85 [95% CI +/‐ 0.09] p=0.02), with a cut‐off value of 2.5cm determined assuming equal weight to sensitivity and specificity. All DNSIs were successfully treated with no adverse outcomes, and there was no significant difference in LoS between groups. In those managed surgically, outcome and LoS did not depend on yield of pus.

Conclusions

Selected paediatric DNSIs can be successfully managed conservatively, with abscess diameter >2.5cm a significant predictor of need for surgical intervention. Any benefit of surgery does not appear to depend on intra‐operative yield of pus.
