What Causes Laryngitis?

Chronic Sinusitis

Chronic sinusitis is a condition where an individual experiences long term inflammation of the sinus linings. Sinuses are cavities in the facial bones behind the nose that are normally filled with air. The inner linings of the sinuses are membranes responsible for the secretion of thin mucus at times when it is needed. When these membranes become inflamed due to allergies or another mechanism, they can produce an excessive amount of thick mucus. This excessive mucus can drain into the back of the patient's nose and down into their throat. The tissues that make up the throat and larynx are not meant to have direct contact with thick mucus continuously for an extended period. When post-nasal drip is persistent due to chronic sinusitis, the patient's throat tissues can become irritated, inflamed, and swollen. This inflammation is considered a form of laryngitis.
