What Causes Laryngitis?

Fungal Infection

Most individuals who develop fungal infections that cause the development of laryngitis are immunocompromised due to previous treatments, chronic diseases, autoimmune processes, and other conditions. Cryptococcal, histoplasmosis, aspergillosis, blastomycosis, and candidiasis are the most common types of fungus to produce infectious fungal laryngitis. These fungi have the potential to travel into the vocal folds after they have colonized and caused an infection in the airways, lungs, bronchi, tonsils, or throat. Once the fungi make their way to the secondary location of the vocal folds, they colonize further in these tissues. This fungal colonization induces an inflammatory response by the affected individual's immune system. The immune system releases substances and summons numerous types of white blood cells to the larynx in an attempt to mediate the harmful infection-causing pathogen. This infective inflammation of the vocal cords is a form of laryngitis.
