A 60-year-old man was admitted to a hospital with infarction of the brain stem. Tracheostomy was done and he had breathed through a cuffed tracheal canula for five months. And then, he suffered from suffocation due to growth of polyp like granulation tissue when the canula was exchanged. We tried pure ethanol injection via a flexible bronchofiberscopy to the granulation tissue. The airway obstruction was improved. We thought intratumoral ethanol injection was one of the useful treatment for unfavourable development of the granulation after tracheostomy.
