Description

The Montgomery Laryngeal Keel is a specialized medical device crafted to address anterior subglottic stenosis, with or without the presence of vocal cord paralysis. This device plays a crucial role in post-surgical care, particularly following the repair of stenosis or the removal of a Montgomery Laryngeal Stent. Its primary function is to aid in forming a sharp anterior commissure and to prevent stenosis after procedures such as hemilaryngectomy.

Design and Functionality

• Material: Made from soft, implant-grade silicone, the keel features a non-adherent smooth surface, minimizing tissue interaction.
• Sizes: Available in three sizes—12 mm, 14 mm, and 16 mm—to accommodate varying anatomical needs.
• Variants: Offered in both clear and radiopaque materials, providing flexibility for different clinical requirements.

Surgical Application

The extralaryngeal portion of the keel is designed to be secured to the thyroid laminae using a figure-of-eight suture technique. This positioning covers the thyrotomy repair effectively. When properly secured, the keel serves to prevent the migration of granulation tissue into the larynx, thereby reducing the risk of stenosis and ensuring stable healing.

Key Benefits

• Prevention of Stenosis: By maintaining a clear laryngeal passage, it significantly reduces the risk of tissue adhesion and stenosis.
• Ease of Use: The device's smooth surface and tailored sizing enhance surgical handling and patient compatibility.

Packaging and Sterility

Each keel is supplied sterile, with one keel per carton, ensuring readiness for immediate surgical use and maintaining high standards of hygiene.

The Montgomery Laryngeal Keel is an essential tool for otolaryngologists, designed to support successful surgical outcomes and long-term patient well-being.
