Expandable Metallic Stent in the Treatment of Subglottic Tracheal Stenosis: Report of Long-term Failure in 4 Cases

ABSTRACT

Subglottic stenosis is more likely to develop secondary to endotracheal intubation if one or more traumarelated risk factors are involved. Subglottic stenosis have been dealt with many medicosurgical procedures such as dilatation, stent, laryngofissure with or without skin of mucosal graff, and segmental resection. We report longterm failure of expandable metallic stent in the treatment of subglottic tracheal steno$is in 4 cases which had been presented with respiration difficulty due to framework problem of subglottic trachea after surgical operation.
