Purpose The purpose of this article is to study the relationship between the severity of skeletal Class Ⅲ malformations and the patient's psychosocial and therapeutic requirements and outcomes. The method used is a hierarchical questionnaire. The object of study was 140 patients with skeletal Class Ⅲ malformations. Of these, 67% (40 males and 54 females) completed and returned the questionnaire. Mandibular protrusion was found in 32% of patients, maxillary retraction in 14% of patients, maxillary retrusion and mandibular protrusion in 54% of patients. 15% of the patients underwent maxillary advancement, 8% simple mandibular retrostectomy, and 77% performed maxillary advancement and mandibular retrograde surgery. Results The ANB angle was negatively correlated with the patient's nickname related to facial deformity and negatively correlated with the operative cause. The postoperative lifestyle change was significantly associated with the size of the ANB before surgery. Conclusion The changes of social psychology before and after treatment of skeletal Class Ⅲ malformations are closely related to the severity of skeletal deformity.
