How long does a Eustachian tube take to naturally unblock?

UNBLOCK. FROM IMMEDIATELLY TO NEVER, YES IT CAN BE PERMANET.
Eustachian tube dysf. The length of Eustachian tube dysfx depends on the original reason why the tube was blocked or not functioning in the first place. If it is a cold: when the cold resolves. If it is a mass or the adenoid as the cause, whenever the tissue is removed. Sometimes it never resolves and people may require the placement of a tube to equilibrate the pressure in the middle ear space. Hope this helps. .
