Could long term use of inhalers cause laryinx problems?

I think that my son is developing hoarse voice. Also I think that it is happening because of his asthma therapy. I am getting worried every day more, because I am not sure if this is occasional or permanent manifestation. What do you think about this matter? Could long term use of inhalers cause larynx problems?

My daughter had the similar larynx problems. At first I didnt know why, but eventually, her doctor explained that cortical therapy could cause this kind of problems. He (the doctor) also told as that hoarseness can also be caused with bad inhalation technique. In order to help my daughter to regain her natural voice, her doctor reduced doses of cortical inhalers as much as he could.
