Shunsui's next appearance will probably confirm whether he was healed off-screen or Kubo just forgot his injuries.

Shunsui and Nanao have been at that spot behind the barrier since Jugo first showed up. I don't see it as likely that they left and came back. But there's no action or talk that implies such a thing happened.

I went back to his previous appearances since Jugo confronted them, but there's no panels that shows his right ear until 559, so it's hard to say if he got his injuries healed earlier and kept the eye patch as a trick, as suggested by Sicarious001.

I suppose I'm over-analyzing this.
