My 2mos son has larynomalacia, tracheomalacia & bronchial problems. is trachea an only option? traheal stent, do they work & are they comfortable?

Tracheomalacia: If the diagnosis is indeed correct, and his is severe enough that it is severely affecting his breathing ability and/or growth, a trach may indeed be one of the few options for him. Most infants do not need their laryngotracheomalacia treated - as the trachea develops on its own, symptoms would resolve. But if severe enough, the airway must be opened and that usually involves a tracheostomy.

Not likely: Tracheal stents are not recommended for benign disease, and the problem with a child would be that as the child grows, the stent does not.
