[Glottic reconstruction with a flap of thyroid perichondrium]

Area of Science:

• Otolaryngology
• Surgical Innovation
• Laryngeal Reconstruction

Context:

• Laryngoplasty is a surgical procedure for voice restoration.
• Vertical partial laryngectomy and cordectomy can impair laryngeal function.
• Novel reconstructive techniques are needed to improve outcomes.

Purpose:

• To describe laryngoplasty techniques using thyroid cartilage perichondrium or sternohyoid muscle flaps.
• To evaluate the anatomical and functional results of this method in glottic reconstruction.
• To assess voice quality and laryngeal function post-surgery.

Summary:

• Laryngoplasty was performed utilizing thyroid cartilage perichondrium or sternohyoid muscle flaps.
• The technique was applied for glottic reconstruction following frontolateral vertical partial laryngectomy and cordectomy.
• Ultrasound imaging confirmed improved laryngeal function, voice timbre, and strength in all 15 cases.

Impact:

• Demonstrates a viable surgical approach for glottic reconstruction.
• Offers a method to enhance voice quality and laryngeal function post-laryngectomy.
• Provides evidence for the effectiveness of perichondrium and muscle flaps in voice restoration.
