The cyst should not disappear naturally, because if there is fluid inside, it is usually due to leakage from the cyst wall, but it is unlikely that the cyst wall can absorb it naturally.

Surgery should not be risky. Yours is an epiglottis cyst, right? You should consult your attending doctor. It should be a relatively simple surgery.

The cyst is not on the vocal cords, so the possibility of impact is very small.

If you are very worried, it is recommended to go to the otolaryngology department of a tertiary-level hospital, where the doctors are relatively better.
