andwich Thyroplasty is a novel advanced technique for simplifying the medialization of Vocal Fold with modification of thyroplasty Window and using silicone implant in Paralytic Dysphonia.
Main advantage of Sandwich thyroplasty technique is easy facilitation, fixation and stabilization of silicone implant avoiding difficult and time consuming techniques involving flanges or sutures.
Surgery for Unilateral Vocal Cord Paralysis:
Correction of Vocal Cord Paralysis
How vocal cord paralysis affects us?
The voice box or larynx has three important functions
The vocal folds have two positions 1. Open (vocal cords are apart) for breathing and 2. Closed (together) for making sound, coughing and sealing off lungs when swallowing
When one vocal fold is paralyzed, the vocal fold usually rests in and in between position. It neither opens for breathing, nor closes for voicing, coughing, or swallowing.
The voice becomes weak and breathy. People can only say a few words per breath or frequently out-of-breath. Swallowing may be affected as well with some choking or coughing with swallowing liquids. Your cough is also frequently different and very weak.
What treatments are offered for Unilateral Vocal Cord Paralysis?
Type-I Thyroplasty with Arytenoid Adduction technique (AAT) or Medialization Laryngoplasty restores function of the larynx by moving the paralyzed vocal fold to the middle. The unparalysed side meets it in the middle for non-breathing functions and results in complete closure. The complete closure is necessary for making sound, coughing and sealing off the lungs when swallowing thus restoring most of functions.
There are two different types of medialization Laryngoplasty; injection and implantation. The injection may be done in the clinic with local anaesthesia or in the operating room under general anaesthesia. The permanent implant is done in the main operating room as day care surgery.
How effective is the treatment?
Results: 98% cases are successful at MicroCare ENT Hospital and Research Institute in restoring the speaking voice.
