OBJECTIVE: To describe the clinical profiles, interventions, and surgical outcomes of patients with advanced (grade III and IV) laryngotracheal stenosis prospectively seen over a 2-year period.  

METHODS:

           Design:           Prospective Case Series

          Setting:           Tertiary Provincial Government Hospital

          Participants:  Five (5) patients with advanced laryngotracheal stenosis confirmed by laryngoscopy and/or tracheoscopy.

RESULTS: Five (5) patients (4 males, 1 female), aged 23 to 31years (mean 27-years-old) diagnosed with advanced laryngotracheal stenosis between June 2016 to June 2018 were included in this series. Four resulted from prolonged intubation (14 - 60 days) while one had a prolonged tracheotomy (13 years). Presentations of stenosis included dyspnea on extubation attempt (n=3), failure to extubate (n=1) and failure to decannulate tracheotomy (n=1). Stenosis length was 3 cm in two, and 1.5 cm in three. Of the five (5) patients, three had grade IV stenosis while two had grade III stenosis based on the Cotton-Myer Classification System. Two of those with grade IV stenosis and both patients with grade III stenosis had undergone prolonged intubation. The stenosis involved the subglottis in three, and combined subglottic and tracheal stenosis in two. Prolonged intubation was present in all three with subglottic stenosis, and in one of the two with combined subglottic and tracheal stenosis. Two patients underwent open surgical approaches while three underwent endoscopic dilatation procedures. Four patients were successfully decannulated while one is still on tracheostomy. None of them had post-operative complications.

CONCLUSION:  Advanced laryngotracheal stenosis is a challenging entity that results from heterogenous causes. Categorizing stenosis and measuring stenosis length may help in treatment planning and predicting surgical outcome.

When tracheal invasion of a malignant tumor or tracheal stenosis of a benign origin exists at the lower or anterior part of the trachea, tracheal intubation or conventional tracheostomy may be difficult, and in these cases a modified tracheostomy through the lower or lateral part of the trachea would be necessary. We present 6 cases of modified tracheostomy performed with satisfactory results in severe tracheal stenosis that developed in the lower or anterior part of the trachea.

The treatment of choice for post-intubation tracheal stenosis is partial tracheal resection and end-to-end anastomosis. The surgical treatment of tracheal restenosis that results from unsuccessful repair of post-intubation tracheal stenosis is not easy. Failed reoperation results in permanent tracheostomy and loss of voice. If the first operation fails, about 4~6 months of period for resolution of inflammatory reaction, edema, and fibrosis is needed. The exact evaluation of the patient's status is necessary and success rate of reoperation for the appropriate candidates is over 90%. We report the results of treatment in two cases of tracheal restenosis that resulted from unsuccessful repair of post-intubation tracheal stenosis with review of literatures.
