Laryngeal web most frequently occurs due to acquired rather than congenital factors. It can cause dysphonia and airway disorder depending on the extent of the area or thickness of the web. The prevention of relapse after web resection is the most important aspect of surgery for laryngeal web. A local mucosal flap can be developed using the superior and inferior surface of the web. This flap can cover at least one side of the wound on the vocal fold after web resection, and consequently leads to primary healing. The other technique for preventing web relapse is to place a stent (also called a “keel”) at the anterior commissure after removing the web. A slim silicone tube can be used as a stent to prevent web relapse. A membrane like plate can also be adopted. The round-shaped silicone tube has an advantage in softness for the vocal fold in comparison to a flat-shaped plate. One of the disadvantages of the silicone tube is that it cannot cover the wound that develops after the resection of a broad web affecting the posterior membranous vocal fold. To resolve this problem, we developed a new type of silicone stent that includes both a tube and a plate component. An appropriate surgical method and stent should be chosen based on the condition of the web.
