Dentofacial deformity and orthognatic surgery: Influence on self-esteem and aspects of quality of life.

This study aimed to assess the extent to which psychosocial and functional aspects are affected in orthognathic surgery patients. The Oral Health Impact Profile (OHIP-CRO14), Orthognathic Quality of Life Questionnaire and Self-Esteem (SE) Scale were used. The sample included 110 Caucasian subjects (73% females) aged 19-54 years. Fifty-five patients with dentofacial deformities were treated by combined orthodontic-orthognathic surgical treatment, and 55 others, matched by sex and age, were untreated controls without dentofacial deformities. In comparison with the untreated subjects, patients before surgery had a poorer quality of life, with the largest effect size in oral function (OF) and OHIP (average differences 8.0 and 14.7, respectively; p < 0.001; r = 0.65 and 0.63), while the lowest effect sizes were in awareness of facial aesthetics (AW) and SE. The treatment induced statistically significant changes in all psychosocial and functional aspects, mainly with a large effect size (p < 0.001; r = 0.48-0.78). The major effect size was a decrease in facial aesthetic concerns (FE; 7.6 +/- 6.2; p < 0.001; r = 0.78), followed by a decrease in impairment of OF and OHIP (8.0 +/- 7.1 and 16.6 +/- 14.6; p < 0.001; r = 0.75). The lowest effect size was in the decrease in AW and increase in SE. After surgery, all aspects were similar to those in the untreated subjects. In conclusion, facial deformity raises many issues, primarily related to aesthetic concerns and functional impairment; however, orthognathic surgery manages to improve quality of life to be similar to that of the population without deformities.
