Unlikely that they won't survive. However, they may take some time to regain size. Do you have pictures?

If they were mine, I would do nothing until new growth started, then clean and repot. At least wait awhile before deciding about throwing them away.

Are there any leaves left?

Year before last the same thing happened to some of my Catts.hail blew in under a canopy they were under . I watched the damaged leaves for rot, none showed up . They still look bad but in time I can divide off the damaged part .. Gin

You might just wipe down the damaged leaves with a cotton ball dipped in hydrogen peroxide, and then hope for the best. The damage may be cosmetic. The damaged leaves are necessary for the health of the plant, so don't remove them unless they start to rot.
