A case of 42-year-old man with postintubation subglottic stenosis underwent primary thyrotracheal anastomosis. Since trachea had been incised longitudinally for previous tracheostomy, tracheal resection came to be longer. Therefore, we had to anastomose the incised trachea with thyroid cartilage even after the suprahyoid release. After the operation, he suffered from the tracheal collapse at the incised portion of the trachea One week after intubation, tracheal patency was achieved. We recommend horizontal incision for tracheostomy in patient with subglottic stenosis, when the following surgical approach is considered.
