The treatment of choice for post-intubationtracheal stenosis is partial tracheal resection and end-to-end anastomosis. The surgical treatment of tracheal restenosis that results from unsuccessful repair of post-intubationtracheal 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-intubationtracheal stenosis with review of literatures.
