Interleaved mean values with the related standard error of mean (SEM) of the measured angular and linear changes in the hard and soft tissue profiles in moderate and pronounced Class II and Class III patients after monomaxillary surgery, bimaxillary surgery, and premolar extractions. MnA: mandibular advancement, MnS: mandibular setback, MxA: maxillary advancement, MxS: maxillary setback. Angular skeletal measurements: SNA (blue); SNB (green); maxillary inclination, NL-NSL (red); mandibular inclination, ML-NSL (purple); skeletal profile, N-A-Pog (yellow). Linear measurements in the soft tissue profile: upper lip length, Sn-Sto (blue), upper lip thickness, A–A’ on NL (black), upper lip to esthetic line, Ls-E-line (red), upper lip length, Sto- Gn’ (yellow), upper lip thickness, B–B′ on ML (purple), lower lip to esthetic line, Li-E-line (green). Angular measurements in the soft tissue profile: facial profile, N′-Prn-Pog’ (black), soft tissue profile, N′-Sn-Pog’ (blue), nasolabial angle, Cm-Sn-Ls (red), mentolabial angle, Pog’-B′-Li (Yellow), lip-chin-throat angle, LiPog’-Gn’H (green)
