The larynx is called “voice box”. It is the vital part of the respiratory tract which allows the air to pass through it and keeps the food and drink from blocking the air ways. The main function of the larynx is to produce the sounds while you talk and sing.
When the larynx is inflamed, the condition is referred as laryngitis. Inflammation can be a result of overuse, irritation or infection. The two main types of laryngitis are chronic type and acute type.
Acute laryngitis is temporary and is caused by overuse or due to any underlying infection. Chronic laryngitis can be caused due to the long-term exposure to harmful chemicals.
The major causes of acute laryngitis are viral infections, the strain on vocal cords, or may be due to any bacterial infections.
The major causes of chronic laryngitis are, acid refluxes, overusing of voice, infections such as sinusitis, smoking and frequent exposure to harmful allergens.
The common symptoms of laryngitis may include dry cough, loss of voice, throat irritation, weakened voice, hoarseness in voice.
Croup is a symptom that occurs in infants and small children who are attacked with a bacterial form of laryngitis. Croup is an inflammation of the throat which may develop into epiglottitis. Epiglottitis can become fatal if left untreated.

Your doctor may rather use a fiber-optic Laryngoscopy by inserting a flexible tube which has a tiny camera; this helps your doctor to visualize the motion of your vocal cords.
Biopsy: if your doctor finds anything suspicious your doctor may take a sample of the tissue for biopsy.
Acute laryngitis is self-limiting and gets better within a week or two. Following certain self-care measures would also fasten the recovery and improves the symptoms.
The goal of treatment for chronic laryngitis is to treat the underlying causes, such as heartburn, smoking or alcohol addiction.
