Umbrella Keels are designed for use following repair of anterior laryngeal stenosis, subsequent to removal of a laryngeal stent, to insure reformation of a sharp anterior commissure and to prevent formation of an anterior web. Clear umbrella keels are also available. Both are indicated for use after hemilaryngectomy to prevent stenosis. The soft, conforming structure consists of an umbrella-like extralaryngeal cover and a thin intralaryngeal insert. The extralaryngeal surface is secured to the thyroid laminae to protect the thyrotomy repair. It is designed so that, with a Last figure suture, the keel can be held tightly enough to inhibit synchronous motion between the intralaryngeal keel insert and the vocal cords, thus preventing granulation formation and preserving phonation.Design Benefits: • Helps to repair of anterior glottic stenosis and to protect the thyrotomy repair.• Prevention of stenosis following hemilaryngectomy.• Formation of a sharp anterior commissure subsequent to removal of laryngeal stent.• Soft, solid conforming structure.• Solid and soft structure consisting extralaryngeal cover with a thin intralaryngeal insert.• Anti-adherent smooth surface.• Available in Clear or White material.• White umbrella keel enables easy visualization for removal.Material: Medical Grade Silicone.
