I guess we are going to need a bit more information.

Did you do the mastering or have it done?

What is the instrumentation and the genre?

If you did the mastering what equipment did you use?

If it was done by someone else did you attend the sessions?

Have you looked at the waveforms have you checked for overs?

What are you monitoring on.

I think you get the idea....

Sibilance can go from "noticeable" to "abhorrent" very quickly during the mastering phase. As can noise, hiss, distortion, excessive effect processing, excessive dynamics processing, etc.

I'm not saying it should come back "worse" -- But I'd advise listening to the original mixes again and finding out if the problem was already there... It's rather common.

did the ME use a Desser on the mixes?

You've already gotten good info, but here's my take:
Mixes that have problematic SSS's and sibilance are only made worse by compression. The more compression added, the worse they get.
Often, "bad" mastering jobs are most easily spotted by these and other artifacts. However, in some cases, the mix itself is teetering on the edge of this when it goes to the ME and even light compression and limiting pushes it over the edge.

As has already been suggested, check the originial mixes for problems with the Ssssss and listen critically.

If the noise isn't in the mix, there is no reason why it should be in the master. The master was not mastered correctly. Someone was touching knobs they shouldn't of been touching.

Honestly man, I run a mastering studio, and SSSS do not happen, When the SSSS appeared your mastering engineer should have correctly de-essed the mix, and sent your track back cleaner, clearer then before you sent it

i found some of my Ssss.. part was distort after Mastering stage..what's this caused by? BTW, Final Mix doesn't have problem on this

Sometimes an added boost in the 4 to 10k range can inadvertently accentuate the sibilance...if that, in turn gets over compressed and/or over limited = saturated sibilance, sometimes...
