Chronic laryngitis is a condition of an infection of the larynx that persistts for more than 3 months. In most cases a bacterial infection is present. Leukoplakia (whitish covering on the interior mucosa of the upper airway within the larynx), redness, swelling and voice problems are frequently present. The voice can be partially lost (severe hoarseness) or totally lost (aphonia), when the vocal folds are markedly affected.
Reflux and other related factors such as allergies and even breathing problems (including asthma) should be ruled out. Chronic laryngitis may be difficult to treat, even if many antibacterial agents were given. In cases of refractory treatment, antifungal medication and ‚photodisinfection’ with a special photoangiolytic laser (KTP, blue laser) may be helpful.
