If your voice changes and sounds different when you move your face from left to right, and sounds different from side to side, this is thought to be caused by the following reasons:
(1)The stylopharyngeus muscle has a different balance between the left side and right side.
(2)The connective woven fibers of the middle constrictor has a different sized mass between the left and right.
(3) The spatial configuration of the pharyngeal cavity is not symmetrical.
A singer recently asked me,” why does my audience say that my singing sounds different, from the right to left side? My doctor assured me that there is no problem with my vocal chord at the otological hospital. What is your opinion?”
I inspected, and observed that the right stylopharyngeus muscle is more strained than left. If he faces to the right, the thyroid cartilage is pushed in and makes the resonance chamber deeper and narrow.
Actually, I only noticed that his voice sounded different when compared, while facing to the right and left in a soundproof room. I will use neuromuscular electrical stimulation to treat this. First, I altered the electrical traction, targeted specific currents, and changed the angle to precisely 10 degrees in order to focus on stretching only the right stylopharyngeus muscle. Then, I exerted traction with 13lbs of pressure for 15 minutes.
I then administered to the right stylopharyngeus muscle “ultrasonic therapy,” using 3MHz, at 50% and 2W for 10 minutes. The final step to this procedure is carefully stretching the styloid process, to the edge of the thyroid cartilage.
After giving him a few treatments and several follow up visits, he showed major (permanent) improvement to the continuity of sounds produced by the right and left side.
From my experience, I believe that the most common cause of such vocal issues is (1).
Be careful … if your voice changes from left to right, and please seek professional vocal therapies
– There is hope!
The above figure refers to: the stylopharyngeus muscle, the thyroid cartilage, the cricoid cartilage and the tracheal cartilages, which can be observed from the left to the rear.
