Conservatively treated extended tracheal necrosis complicating pharyngolaryngectomy.

Tracheal necrosis is a rare life-threatening phenomenon that most often occurs after thyroid operations or prolonged intubation. Conservative treatment can be one choice in extensive tracheal necrosis. We report the case of a 59-year-old man, with tracheal necrosis that developed after pharyngolaryngectomy, that we treated conservatively using hyperbaric oxygen therapy and antibiotic therapy. The follow-up was assured by tracheobronchoscopy. A year after his discharge, the trachea was totally healed.
