My theory is that when Hide told Kaneki to eat him to regain his strength, he ended up taking a chunk out of his face and throat, explaining the mask and scar. This brings Hide's race into question. In the the updates re release of chapter 1, Hide implies that he is a ghoul. Being a ghoul could have helped him survive Kaneki eating his face but being lower ranked(for now) his regeneration might not have been strong enough to fully heal.
