RESUMO
OBJECTIVE: Dentofacial deformities can affect patient "quality of life" (QoL), and orthognathic surgery can improve this QoL. The aim of the present study is to assess changes in QoL in Moroccan adult patients with dentofacial deformities undergoing orthodontic surgical treatment. METHODS: 32 patients (21 females and 11 males; mean age 27±5.96 years) completed a specific questionnaire of QoL once the surgical phase is completed. The questionnaire includes 22 questions marked on a 4-point scale depending on how much the question covered by the statement disturbs the respondent. The 22 questions contribute to four aspects: social aspects of dentofacial deformities, facial aesthetic, oral function, and awareness of dentofacial aesthetics. RESULTS: A significant difference in QoL was observed before surgery between men and women. On the other hand, 73.6% stated of patients said that they were uncomfortable by their dentofacial appearance before surgery, and almost half of the patients have made functional limitations before surgery. After surgery, 85.42% of patients reported a positive change in their QoL. Class III patients reported greater pre-surgical aesthetic and functional restrictions than Class II skeletal patients. In post-surgery, patients in both skeletal classes showed significant improvement in their QoL, so improving the aesthetics, oral functions and self-confidence are the main motivators to seek orthognathic treatment for our patients. CONCLUSION: Improving the aesthetics, oral functions and self-confidence are the main motivators to seek orthognathic treatment for Moroccan patients.
