How long nebulizer inhalation needs to be done is influenced by many factors. Usually vocal fold hypertrophy caused by inflammation is treated with hormonal drugs in most cases when nebulized inhalation is performed because of the presence of acute inflammation. For example, budesonide, etc., so its treatment time should be generally limited to 2-3 weeks. If the patient has a long history of asthma or a longer period of antibiotic use elsewhere in the body, the duration of nebulized inhalation in this case should be reduced accordingly. This is because excessively prolonged nebulization can lead to secondary infection in the throat. If there are no such reasons, the nebulized inhalation is rehydrated with saline only, and the duration of such nebulization can be extended accordingly.
