Management of Severe and Complex Hypopharyngeal and/or Laryngotracheal Stenoses by Various Open Surgical Procedures: A Retrospective Study of Seventeen Patients

Objective: To systematically study various surgical approaches for treating complex hypopharyngeal and/or laryngotracheal stenoses at a variety of sites and levels. Patients and Methods: We retrospectively analyzed the treatment of 17 patients with severe and complex hypopharyngeal and/or laryngotracheal stenosis at various sites and levels of severity. All of the 17 patients initially had a tracheostomy. Thirteen had failed the previous laser lysis and/or dilation treatment. Given the high severity and complexity of stenosis, all of these patients were treated by open surgical reconstruction techniques using repairing grafts (flaps), followed by stenting. Results: Thirteen of 17 patients had successful decannulation 1-8 months post-operation and had stable airway and adequate vocal and swallow function. Two patients with complex hypopharyngeal and esophageal stenosis had unsuccessful decannulation. Follow-up was lost in 1 patient with complex hypopharyngeal and esophageal stenosis and 1 patient with original hypopharyngeal stenosis and recurrent thoracotracheal stenosis. Conclusion: Despite the failure by the regular treatments using laser lysis and/or dilation therapy, severe and complex hypopharyngeal and/or laryngotracheal stenosis may be successfully treated by variable open surgical reconstruction techniques using different grafts (flaps) depending on the site and severity of the stenosis.
