Use of the Keel can be made following repair of stenosis or following removal of the Montgomery® Laryngeal Stent to aid in formation of a sharp anterior commissure.

The Keel can also be beneficial to prevent stenosis following a hemilaryngectomy. 

The extralaryngeal portion, when secured to thyroid laminae with a figure-of-eight suture, covers the thyrotomy repair with its umbrella.

Tightly secured, the keel prevents stenosis and the migration of granulation tissue into the larynx.
