Tracheal Stenosis: Evaluation of an Institutional Protocol and Introduction of Novel Surgical Criteria and Scoring System.

Treatment modalities for treatment of post intubation and post tracheostomy tracheal stenosis are many. However, well defined surgical criteria and prognostic classification eluding us till date. A prospective study of 57 cases of post intubation and post tracheostomy tracheal stenosis managed as per well defined surgical criteria followed in our institution. Patients were divided into three groups as per the primary surgical procedure used. The stenosis was classified into mild, moderate and severe based on our proposed prognostic classification. The success rate of endoscopic procedure was 81% with average 1.6 number of procedures per patient, for tracheoplasty success rate was 63% with 1.4 number of procedure per patient, and similarly for tracheal resection and anastomosis was 90% with 1.1 procedure per patient. The patient score as per our proposed classification correlated well with the prognosis. Our surgical criteria correlates well with success rate reported by other authors and can be helpful for institutions or surgeons dealing with tracheal stenosis occasionally. Our prognostic classification can be used to predict prognosis. © Association of Otolaryngologists of India 2019.
