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.
Method:
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.
Conclusion:
This method ensures that pharyngeal closure has been technically adequate.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
