Many patients are hospitalized in our rehabilitation center with swallowing disorder and/or speech disorder after tracheotomy. Among 99 patients examined, tracheal cannula exchange was performed on 76, 35 underwent laryngeal endoscopy. Of the 76 patients cited, 66 developed granulation tissue, which was significant in 25; airway obstruction occurred in 21 when the tracheal cannula was removed; and re-insertion was difficult in 13 cases. To prevent granulation tissue formation, the tracheal mucosa and skin should be sutured to create a tracheal cartilage flap. For long-term tracheal cannula use, percutaneous tracheotomy should be avoided. As a method of treating granulation, trichloracetic acid and a power punch have proven effective.
