Larynx diseases refer to a range of medical conditions that affect the larynx, which is commonly known as the voice box. The larynx is a crucial structure located in the throat, responsible for producing sound, allowing air to reach the lungs while preventing food and liquids from entering the airway.
Various diseases can affect the larynx, leading to different symptoms and complications. Some common larynx diseases include laryngitis, vocal cord polyps, vocal cord nodules, vocal cord paralysis, laryngeal cancer, and laryngopharyngeal reflux.
Laryngitis is the inflammation of the larynx, often caused by viral or bacterial infections, overuse, or irritation due to environmental factors such as smoking. Symptoms include hoarseness, coughing, sore throat, difficulty in speaking, and sometimes a loss of voice.
Vocal cord polyps and nodules are benign growths on the vocal cords, typically caused by vocal strain, excessive use, or trauma. They can cause voice changes, hoarseness, and difficulty in speaking.
Vocal cord paralysis occurs when one or both of the vocal cords cannot move or vibrate properly. This condition can result from nerve damage, injury, or certain medical conditions, leading to voice changes, weak voice, swallowing difficulties, and breathing problems.
Laryngeal cancer refers to the growth of cancerous cells in the larynx, which may lead to changes in voice, persistent hoarseness, difficulty swallowing, and breathing issues.
Lastly, laryngopharyngeal reflux (LPR) is a condition where stomach acid flows back up into the larynx, causing irritation and inflammation. Symptoms include a sore throat, chronic cough, hoarseness, and the
