Many patients ask me “How to treat chronic laryngitis?” Of course, we should treat the cause of chronic pharyngitis. We must first carefully analyze the medical history, living habits, work background and environment, our own physical condition, resistance, allergy history, etc. to find the cause. Of course, some patients may have difficulty finding the cause. In fact, in most cases, chronic laryngitis does not require special treatment, but rather care to keep away from or avoid the cause of the disease.
