Causes of change in voice
Acute laryngitis is the most common cause of hoarseness and voice loss that starts suddenly. Usually caused by viral infection.When the vocal cords swell, they vibrate differently, leading to hoarseness. The best treatment for this condition is to stay well hydrated and to voice rest.
Laryngopharyngeal Reflux Disease (LPR)
Reflux of stomach juice into the throat can cause a variety of symptoms in the esophagus (swallowing tube) as well as in the throat. Hoarseness (chronic or intermittent), swallowing problems, a lump in the throat sensation, or throat pain are common symptoms of stomach acid irritation of the throat.
Benign Vocal Cord Lesions
Non-cancerous growths on the vocal cords are most often caused by voice misuse or overuse, which causes trauma to the vocal cords. These lesions (or bumps) on the vocal cord(s) alter vocal cord vibration and lead to hoarseness. The most common vocal cord lesions are nodules, polyps, and cysts. Vocal nodules occur on both vocal cords opposite each other at the point of maximal wear and tear, and are usually treated with speech therapy.if they doesn’t resolve. It has to be treated by surgery. Vocal cord polyps and cysts are the other common benign lesions. These types of problems typically require microlaryngeal surgery with conventional, laser or use of coblation technique.
Coblation has distinct advantage over laser as heat generated in coblation is quite lesser than any laser, so injury to surrounding areas will be much lesser with accurate precision
Vocal cord paralysis\paresis–
many conditions cause these. After identification of initial cause we do necessary training or surgery for relief of breathing or correction of voice
