Okla. Stat. tit. 21, § 758

Where it appears, upon a trial for maiming another person, that the person injured has, before the time of trial, so far recovered from the wound that he is no longer by it disfigured in personal appearance, or disabled in any member or organ of his body, or affected in physical vigor, no conviction for maiming shall be had; but the accused may be convicted of assault and battery, with or without a special intent, according to proof.
