Hood Laryngeal White 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, solid 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 figure-of-eight 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.
The Hood Intended Use and Instruction Manual, which is supplied with each product, provides detailed information on insertion technique, sterilization, and postoperative care.
