Doctor learns to speak after losing his voice-box to cancer

The voice box, or larynx, has three important functions. It is necessary for breathing, voice and
swallowing. The vocal folds have two positions, open (apart) for breathing (picture I) and closed (together) for
making sound, coughing and sealing off the lungs when swallowing (picture II). When one of the vocal folds are paralyzed, it usually rests in an in-between position (picture III), and neither opens for breathing, nor closes
for voicing, coughing, or swallowing. Usually, the effects on the voice are the most dramatic. The voice becomes weak and breathy. People can only say a few words per breath, and are frequently
out-of-breath, or physically tired when trying to speak for more than a few minutes straight. The voice may also get somewhat high and squeaky, with a diminished range. Swallowing may be affected as well, where you may notice some choking or coughing with certain liquids. Your cough is frequently different and very weak. This is a serious problem for patients with with vocal fold paralysis because one of the most important functions of the larynx is to keep liquids out of the lungs, and to be able to cough up mucus. When this does not happen, you are at risk for getting an "aspiration" pneumonia. The surgical procedure to restore these important functions is called "medialization laryngoplasty"

While a Laryngectomy operation means that you will lose your voice box, there are now many ways you can speak again. There continues to be advances in surgery and post operative rehabilitation which mean that it is rare to be voiceless for long. Getting your voice back is a joint effort between you and your Speech Pathologist. He or she has been trained and has experience in helping Laryngectomees regain the power of speech.

Sometimes the gap between the vocal folds is too great to be closed with an implant alone. Additionally, a very large gap can significantly impair the swallowing, with liquids frequently going down the "wrong pipe." In these cases, it may be preferable to move the cartilage of the vocal cord as well as placing an implant. This procedure is called an arytenoid adduction, and is done in conjunction with medialization laryngoplasty. In contrast to just placing an implant (medialization laryngoplasty), repositioning the cartilage (arytenoid adduction) is much more involved because this cartilage is on the back side of the voicebox. The goal of the procedure is to move the vocal cord cartilage into the middle, closing the gap between the vocal cords which contribute to to the voice and swallowing problems (see diagram below).

THE OPERATION   You will be surprised to learn that although you will experience some pain after surgery, it will probably only be on the level of a sore throat. The doctor will give you a pain killer if you need it. In a total Laryngectomy, such as you are about to have, your voice box or larynx and the tissue around it will be removed. When your larynx is removed, you also lose the natural ability to stop food and liquid entering your lungs. Therefore, to make your breathing safe, your surgeon moves your windpipe or trachea to the front, near the base of your neck.
