Description

The Montgomery Laryngeal Keel is a specialized medical device crafted to address specific laryngeal conditions such as anterior subglottic stenosis. This device is particularly beneficial for patients with or without vocal cord paralysis, providing essential support following the repair of stenosis or the removal of a Montgomery Laryngeal Stent.

Key Features

• Material: Constructed from soft, implant-grade silicone, the keel features a non-adherent smooth surface, minimizing tissue irritation.
• Size Options: Available in three sizes—12 mm, 14 mm, and 16 mm—to accommodate varying anatomical needs.
• Visibility: Offered in both clear and radiopaque materials, enhancing versatility in clinical settings.
• Sterility: Each keel is supplied sterile, with one device per carton, ensuring readiness for immediate use.

Functional Design

The design includes an extralaryngeal portion that, when secured to the thyroid laminae with a figure-of-eight suture, effectively covers the thyrotomy repair. This configuration is crucial in preventing stenosis and inhibiting the migration of granulation tissue into the larynx, thereby promoting optimal healing conditions.

Clinical Benefits

By forming a sharp anterior commissure, the Montgomery Laryngeal Keel plays a vital role in maintaining laryngeal structure and function. It is also instrumental in preventing restenosis following procedures such as hemilaryngectomy, contributing to long-term patient outcomes.

This device exemplifies precision engineering and thoughtful design, making it an invaluable tool for otolaryngologists in managing complex laryngeal repairs.
