title: Cricotracheal resection for airway reconstruction: The Sheba Medical Center experience.
abstract: BACKGROUND
  Intubation and tracheostomy are the most common causes of benign acquired airway stenosis. Management varies according to different conceptions and techniques.
  
  
  OBJECTIVE
  To review our experience with cricotracheal resection and to assess related pitfalls and complications.
  
  
  METHODS
  We examined the records of all patients who underwent CTR in a tertiary referral medical center during the period January 1995 to April 2005.
  
  
  RESULTS
  The study included 61 patients (16 women and 45 men) aged 15-81 years. In 17 patients previous interventions had failed, mostly dilatation and T-tube insertion. Complete obstruction was noted in 19 patients and stenosis > 70% in 26. Concomitant lesions included impaired vocal cord mobility (n=8) and tracheo-esophageal fistula (n=5). Cricotracheal anastomosis was performed in 42 patients, thyrotracheal in 12 and tracheotracheal in 7. A staged procedure was planned for quadriplegic patients and for three others with bilateral impaired vocal cord mobility. Restenosis occurred in six patients who were immediately revised with T-tube stenting. Decanulation was eventually achieved in 57 patients (93.4%). Complications occurred in 25 patients, the most common being subcutaneous emphysema (n=5). One patient died of acute myocardial infarction on the 14th postoperative day.
  
  
  CONCLUSIONS
  CTR is a relatively safe procedure with a high success rate in primary and revised procedures. A staged procedure should be planned in specific situations, namely, quadriplegics and patients with bilateral impaired vocal cord mobility.
