title: Hydrogen peroxide aids assessment of pharyngeal closure after laryngectomy.
abstract: OBJECTIVE
  Pharyngocutaneous fistula is a serious complication following total laryngectomy. We report a simple technique which is useful in assessing the adequacy of pharyngeal closure following total laryngectomy.
  
  
  METHODS
  Installation of 1.5 per cent hydrogen peroxide into the oral cavity, while observing for leakage at the pharyngeal repair.
  
  
  RESULTS
  We have found this technique to be useful in 22 patients undergoing total laryngectomy with pharyngeal resection and neck dissection.
  
  
  CONCLUSIONS
  This method ensures that pharyngeal closure has been technically adequate.
