Larynx

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Background:

Vocal fold paralysis, affecting voice and breathing, severely diminishes patients' quality of life.
Unilateral paralysis causes glottis insufficiency and hoarseness; bilateral paralysis impairs respiration and exercise capacity.
Bioimplants have been a cornerstone in treating persistent vocal fold paralysis for over a century.

Purpose of the Study:

To review the historical and current applications of bioimplants in treating vocal fold paralysis.
To highlight the diverse range of bioimplantable materials and devices available.
To emphasize the importance of adhering to recommendations for optimal patient outcomes.

Main Methods:

Review of historical and contemporary literature on bioimplants for vocal fold paralysis.
Categorization of bioimplants based on material type (autologous, injection, composite, electrical).
Analysis of treatment efficacy and quality of life improvements associated with different bioimplant strategies.

Main Results:

A wide array of bioimplants, including tissue grafts, injectable fillers, thyroplasty devices, and neurostimulators, are available.
Successful application of bioimplants, when used as recommended, leads to significant improvements in vocal function and respiration.
Patient quality of life is substantially enhanced through effective bioimplant interventions.

Conclusions:

Bioimplants represent a vital therapeutic modality for vocal fold paralysis.
The selection and appropriate use of bioimplants are crucial for restoring function and improving patient well-being.
Continued advancements in bioimplant technology promise further enhancements in managing this condition.
