Thyroplasty in India
What is Thyroplasty?
Thyroplasty is a surgical procedure performed to implant a device in the larynx or voice box, specifically alongside the vocal cord. This procedure involves adjusting the position of the vocal cord to enhance its strength. The implant serves the purpose of helping the paralyzed vocal cord reach the midline. The surgery aims to address issues resulting from vocal cord weakness, such as difficulties in swallowing leading to choking or coughing, and it also corrects voice disorders.
Different Types of Thyroplasty
Type 1 Thyroplasty : The surgical procedure involves bringing the vocal cords closer together to alleviate the effects of abductor spasms.
Type 2 Thyroplasty : The surgical procedure is carried out by inserting a shim to separate the vocal cords, preventing them from coming into contact during spasms.

Vocal Cord Paralysis
Vocal cord (vocal fold) paralysis is a condition that impacts the voice due to a disorder. It occurs when one or both vocal folds (vocal cords) fail to open or close correctly. Vocal fold paralysis can be classified into two types :
Bilateral Vocal Cord : In this type, both vocal cords are affected, remaining stuck midway between paramedian positions and exhibiting no movement.
Unilateral Vocal Fold Paralysis : In this scenario, only one side is paralyzed, positioned between a state of closure and openness. The paralyzed fold fails to vibrate with the unaffected fold, leading to either abnormal vibration or complete lack of vibration. Individuals experiencing this type of vocal cord paralysis often struggle to speak clearly and effectively. It is the most prevalent form of vocal cord paralysis.
Symptoms for Vocal Cord Paralysis
Vocal Cord Paralysis Causes
Paralysis can be triggered by factors such as tumors, strokes, diseases, and head and neck injuries. The vagus nerve, responsible for controlling the movement of the vocal cords and extending from the brainstem to the voice box (larynx), can be affected. Damage or injury to the vagus nerve stands out as the primary cause of vocal cord paralysis.
