Assessment of the impact of orthodontic-surgical treatment on the quality of life of patients with mandibular prognathism

Abstract

Background/Aim. Mandibular prognathism as one of the more severe forms of dentofacial deformities impairs the oral functions and appearance of the patient's face and represents a psychosocial handicap with a negative impact on their quality of life. This study aims was to assess the impact of orthodontic-surgical treatment on the quality of life of patients with mandibular prognathism. Methods. The study involved 40 patients (19 men and 21 women, mean age 24.1 ? 4.10) who underwent orthodontic-surgical treatment of mandibular prognathism. All patients completed two questionnaires, the Oral Health Impact Profile (OHIP-14) and the Orthognathic Quality of Life Questionnaire (OQLQ), before the start of treatment and 12 months after the completion of treatment. Results. Both questionnaires showed an improvement in the quality of life compared to the condition before the start of treatment. According to the OQLQ questionnaire, there was a postoperative improvement in quality of life (M = 24.83 ? 12.99) compared to the preoperative period (M = 51.28 ? 15.2). According to the OHIP questionnaire, there was a postoperative improvement in quality of life (M = 11.34 ? 2.99) compared to the preoperative period (M = 20.8 ? 6.88). The improvement of quality of life 12 months after treatment occurred in all segments measured by both questionnaires. Conclusion. Orthodontic-surgical treatment of mandibular prognathism improves all oral functions, the appearance of the patient's face, and thus improves the quality of life.
