Im sure we all have seen the latest chapter. Anyway with the help of onoki, raikage was able to break 2 of susanoo ribs, susanoo was in v2 though.
Anyway it seems damage to susanoo, which is just any other ninjutsu can be healed, be deactivating it. Example is when raikage cracked sasuke's susanoo in v1. Yet when sasuke activated it again in v1/2 against danzou it didnt have this scar. Infact when sasuke used v2 form at the kage summit his susanoo seeemed to have healed.
Either deactivating it and activating it, or using its complete form to heal this
