[Experiences with the augmentation of vocal cords]

Area of Science:

• Laryngology
• Biomaterials Science

Context:

• Vocal fold augmentation addresses glottic insufficiency, often due to recurrent laryngeal nerve paresis or post-tumor resection.
• Current methods include injectable materials and surgical repositioning, each with limitations.

Purpose:

• To evaluate the efficacy and safety of different vocal fold augmentation materials.
• To highlight porous polyethylene (PHDPE) as a superior alternative for vocal fold augmentation.

Summary:

• Injectable materials like Teflon paste carry risks such as overcorrection and systemic absorption.
• Solid implants, particularly porous polyethylene (PHDPE), demonstrate excellent tissue tolerance and stable fixation via connective tissue ingrowth.
• Photokymography is a valuable tool for assessing treatment outcomes.

Impact:

• Porous polyethylene offers a promising, biocompatible solution for vocal fold augmentation, improving patient outcomes.
• This research provides evidence-based guidance for selecting materials in laryngological procedures.
• Enhanced glottic closure can significantly restore voice function and quality.
