PURPOSE: Tracheobronchomalacia is a respiratory disorder that results from abnormal cartilage development. Since 2003, we have performed external stabilization for severe tracheobronchomalacia using separated ring-reinforced expanded polytetrafluoroethylene (ePTFE) grafts. The aim of this study was to analyze the short- and long-term outcomes of our procedure. METHODS: We reviewed the charts of patients who underwent external tracheobronchial stabilization from January 2003 through December 2012. Separated ring-reinforced ePTFE grafts were fixed to the anterior and posterior lesions of malacia independently, with confirmation of a well-opened lumen by bronchoscopy. RESULTS: Five children with severe tracheobronchomalacia underwent six operations. The median follow-up period was 43 months (range 11-109 months). There was no operative mortality associated with the procedure. One patient required removal of a section of the graft owing to the development of bronchial granulation tissue at the site of fixation. All patients showed improved respiratory function, and tracheal growth was confirmed by follow-up computed tomography. CONCLUSIONS: External stabilization with separated ring-reinforced ePTFE grafts for severe tracheobronchomalacia is effective, less invasive than alternatives and preserves the growth potential of the affected airway segment.
