The cutting balloon for endoscopic dilatation of pediatric subglottic stenosis

In recent years, the increasing use of endoscopic techniques for management of pediatric subglottic stenosis has become evident. However, two problems encountered with conventional balloon dilatation are that of re-stenosis and distal balloon migration. We report a novel technique of endoscopic dilatation using the Peripheral Cutting Balloon™ Microsurgical Dilatation Device in a 4-year-old child with symptomatic Cotton Grade 2 subglottic stenosis. The presence of microsurgical blades on the balloon allows for more secure placement of the balloon at the level of the stenosis, preventing migration and allowing for more accurate dilatation under less pressure decreasing re-stenosis rates. We recommend that the cutting balloon be used as first line treatment in pediatric subglottic dilatation.
