title: Patient's Satisfaction in Skeletal Class III Cases Treated With Two-Jaw Surgery Using Orthognathic Quality of Life Questionnaire: Conventional Three-Stage Method Versus Surgery-First Approach.
abstract: OBJECTIVE
  To compare the quality of life (QoL) of Class III patients between conventional three-stage method (CTM) and surgery-first approach (SFA) using Orthognathic QoL Questionnaire (OQLQ).
  
  
  METHODS
  The subjects consisted of 26 Class III patients treated with nonextraction and two-jaw surgery. They were divided into CTM group (N = 15) and SFA group (N = 11). They retrospectively rated the OQLQ scores of 4 domains (social relationship, facial esthetics, function, and awareness of dentofacial deformity) using 0 to 4 scale at initial (T0), just before surgery (T1), 3 month after surgery (T2), and at debonding (T3). Mann-Whitney test and Wilcoxon signed-rank test were performed for statistical analysis.
  
  
  RESULTS
  After total OQLQ score of CTM group was deteriorated at T1 stage compared with T0 stage, it was improved at T2 and T3 stages (T0 = 53.9, T1 = 58.1, T2 = 23.5, and T3 = 11.6). Total OQLQ score of SFA group, however, was improved at T2 and T3 stages compared with T0 stage (T0 = 51.6, T2 =  3.1, and T3 = 11.4; T1 was omitted.). Orthognathic QoL Questionnaire scores and their amounts of change did not show any significant difference in each domain and at each stage between 2 groups (T0, T2, T3, ΔT2 - T0, ΔT3 - T2, ΔT3 - T0; all P > 0.05). Both groups showed large change in effect size (ES) of all domains with descending order during T3 - T0: facial esthetics, oral function, social relationship, and awareness of dentofacial deformity (CTM group: -3.97, -3.40, -2.23, -1.25; SFA group: -2.83, -2.33, -1.76, -1.73) CONCLUSIONS: SFA might have an advantage over CTM group in terms of no deterioration stage of OQLQ score.
