Objective: The aim of this study was to compare the degrees of satisfaction with orthognathic surgery and orthodontic treatment between skeletal Class III and cleft patients.

Materials and Methods: The samples consisted of Class III group (N = 25) and Cleft group (N = 16). The Modified Orthognathic Quality of Life Questionnaires, which had 5 domains (oral function [OF], awareness of dentofacial deformity [ADD], social relationship [SR], facial esthetics [FE], and nose/lip esthetics [NLE]), were evaluated with 5 rates (0 [very satisfactory] to 4 [very unsatisfactory]) at initial visit (T1), just before surgery (T2), 3 to 6 months after surgery (T3), and at debonding or 1 year after surgery (T4). The scores at each stage, amount of change between stages, and effect size (ES) in the 5 domains were investigated.

Results: Compared to Class III group, Cleft group exhibited lower satisfaction scores of NLE domain during all stages (all P < 0.001) and of SR domain and total domains at T4 stage (P < 0.05, P < 0.01). Cleft group showed significant improvement of satisfaction scores in FE domain during T1-T2 (P < 0.01), in SR, FE, NLE, and total domains during T2-T3 (all P < 0.01), in OF, SR, and total domains during T3-T4 (P < 0.05, P < 0.01, P < 0.01), and in all domains during T1-T4 (ADD, P < 0.05; OF, SR, and NLE, P < 0.01; FE and total, P < 0.001). Cleft group exhibited large improvement of ES only at SR and FE domains during T2-T3 (−0.81 and −1.09, respectively).

Conclusions: Owing to lower satisfaction of NLE domain at all stages in cleft patients, clinicians should recommend adjunctive cosmetic surgery for nose and lip after completion of treatment.
