Laryngitis can be divided into acute laryngitis and chronic laryngitis. If the inflammation of acute laryngitis is not controlled in time, it is likely to involve the surrounding tissues to develop inflammation, such as tonsillitis, soft tissue infection in the neck, bronchitis, pneumonia, lymphadenitis, etc. Of course, symptoms of rhinitis may also appear. If chronic laryngitis is present, the symptoms of pharyngeal discomfort may also involve the vocal cords, such as hoarseness or vocal fold hypertrophy, and in severe cases, it may also involve the bronchi or lungs to develop chronic bronchitis, chronic pneumonia, etc. Individuals may also lead to chronic rhinitis, which must be treated with timely intervention for laryngitis.
