Emergency treatment of tracheal tear during pharyngolaryngectomy.

Longitudinal tracheal tear (of the trachealis muscle), an unusual but acknowledged complication of pharyngolaryngectomy, was encountered during a total pharyngo-oesophagolaryngectomy with gastric replacement. Due to serious ventilatory difficulties a rapid repair was required to obtain an airtight seal to allow continued mechanical ventilation. A reinforced polytetrafluoroethylene (PTFE) vascular graft was used as an intratracheal stent to seal the air leak. This technique proved effective and the tracheal defect had healed by the time the stent was removed 10 days later.
