Treatment for Changes in Voice
Interestingly, new studies suggest that treatment with certain steroids prior to thyroidectomy procedures may help improve temporary changes in voice, as well as decrease nausea, vomiting, and pain. This may be worth discussing you're your doctor prior to surgery.
While permanent thyroidectomy effects on voice are rare, there are some ways to treat this condition. Laryngeal electromyography can give information about how the nerves are working, or aren’t working, to control the muscles of the vocal cords, which allows for a definite diagnosis of laryngeal nerve damage. This procedure, along with vidoestroboscopy, which shows your vocal cords in action, and electroglottography, which measures vocal fold vibrations, can be used to make and accurate diagnosis of the problem.
Laryngeal framework surgery, or thyroplasty, can be performed to try to correct problems resulting from a thyroidectomy procedure. Traditionally, laryngeal framework surgery was performed with the hopes of improving the position of your vocal cords so they vibrate better during speaking or singing. This can be used to repair torn, dislocated, or paralyzed vocal cords by bringing them into a better position for a strong voice.
Recently, a technique called laryngeal reinnervation has opened the field to a new treatment option. Although still in its infancy, this surgical procedure may allow for reinnervation of paralyzed vocal cords damaged during a thyroidectomy in which the laryngeal nerves near the thyroid gland were damaged.
