Voice is the sound made by air passing from your lungs through your larynx. Inside the larynx are your vocal cords, two bands of muscle which form the body of the vocal cords. They are covered with an important space (Reinkes space) and a mucosal layer. The vocal cords adduct and vibrate to make sound. For most of us, our voices play a big part in who we are, what we do, and how we communicate. Like fingerprints, each persons voice is unique.
Many things we do can injure our vocal cords. Talking too much, screaming, constantly clearing your throat, or smoking can make you hoarse. They can also lead to problems such as nodules, polyps, and cysts. Other causes of voice disorders include infections, upward movement of stomach acids into the throat (Laryngo-Pharyngeal reflux), growths due to a virus, cancer, and movement disorders of the vocal cords.
Signs that your voice isnt healthy include:-
Your voice has become hoarse or raspy
Youve lost the ability to hit some high notes when singing
Your voice suddenly sounds deeper
Your throat often feels raw, achy, or strained
Its become an effort to talk
It is a sub-specialty within otolaryngology (ear, nose, and throat) that deals with illnesses and injuries of the larynx, often called the voice box. The larynx lies at the beginning of the respiratory system (airways) and contains the vocal cords. The larynx is responsible for protection of the airway, sound production as well as playing an important role in swallowing. Laryngology addresses a wider range of laryngeal disorders besides the voice disorders such as upper airway disorders, and head and neck cancers.
