Diagnosis and therapy of tracheal stenosis

Overview

Background.
The  problem  of  subglottic  and  tracheal  stenosis  is  a problem  that  is  amenable  to  various treatment modalities. Two treatment modalities prevail, endoscopic and external. The indication for each modality is not yet clearly defined.

Methods and Results.
A group of 98 patients suffering tracheal stenosis was studied in the period from January 1994 till December 2004. The stenting procedure was performed in 40 patients, tracheal resection with anastomosis in 20 cases and other endoscopic interventions in 38 patients. Over 10 years the authors introduced 36 Palmaz stents (max. in 4 patients 102 months), 12 Polyflex stents, 4 Wall stents and 1 Z stent. Other patients were treated with carbon dioxide laser and high pressure balon dilatation.

Conclusions.
Based on our long-term experience, open surgery in chronic benign tracheal stenosis is the treatment of choice. However, if contraindications to open surgery exist, whether local or general, endoscopy  with  stenting  by  using  Palmaz  or  Polyflex  stents, laser-assisted  endoscopy  or  balon  dilatation, can offer good palliative results.
