MnS mandibular setback surgery (amount of setback), Pre preoperative, Post postoperative, mo, months
aThe preoperative state (T0) was set as 100%. T0, preoperative; T1, postoperative 1–4 months; T2, postoperative 5–6 months; T3, postoperative 1 year. The total age indicates that the study did not define the value for individual study groups
