title: US-guided needle aspiration and catheter drainage as an alternative to open surgical drainage for uniloculated neck abscesses.
abstract: OBJECTIVE
  To prospectively evaluate the effectiveness of ultrasound (US)-guided needle aspiration and catheter drainage as an alternative to open surgical drainage of uniloculated neck abscesses.
  
  
  METHODS
  Fifteen consecutive patients (11 female, four male; age range from 18 days to 78 years, mean 42.5 y +/- 22.4) diagnosed with deep neck infections associated with uniloculated neck abscesses were treated. The patients were originally scheduled for surgical incision and drainage after a period of unsuccessful treatment with antibiotics. US-guided needle aspiration (in 10 patients) and US-guided catheter drainage (in five patients) were performed under local anesthesia. Open surgical drainage was performed when US-guided drainage procedures failed.
  
  
  RESULTS
  Surgical open drainage was avoided in 13 of the 15 patients (87%). An average of 6 mL of pus was obtained in patients in the needle aspiration group and 140 mL of pus was drained by catheter. One patient had a recurrent pyogenic lymphadenitis at the same location and was treated successfully by repeated needle aspiration. No complications occurred in this study.
  
  
  CONCLUSIONS
  In a selected group of patients without imminent airway obstruction, most uniloculated neck abscesses may be managed initially by US-guided needle aspiration and catheter drainage before resorting to open surgical drainage.
