[Psychological effects of orthognatic surgery and postoperative dissatisfaction: presentation of a research protocol]. / Effets psychologiques de la chirurgie orthognatique et insatisfaction postopératoire : présentation d'un protocole de recherche.

INTRODUCTION: The causes of postoperative dissatisfaction in orthognathic surgery are difficult to grasp. The aims of our study are to analyze the effects of orthognathic surgery on self-esteem, body image, psychological morbidity, and quality of life. We also want to assess the combined effects of these factors on postoperative dissatisfaction, and to study the interest of personality assessment (especially neuroticism) as a predictive factor of dissatisfaction. METHOD: Three hundred patients candidates for maxillo-mandibular osteotomy will be included in the study. They will answer a questionnaire assessing self-esteem, body image, psychological morbidity, quality of life, and personality. The evaluation will be conducted preoperatively and postoperatively at 3 months and at 1 year. The degree of satisfaction will be measured postoperatively. EXPECTED RESULTS: The results should help evaluate the psychological effects of orthognathic surgery and identify predictors of postoperative dissatisfaction, and especially the role of neuroticism.

Orthognathic surgery improves quality of life and depression, but not anxiety, and patients with higher preoperative depression scores improve less.

This study assessed quality of life (QoL), depression, and anxiety before and after orthognathic surgery and identified risk factors for poorer postoperative outcome. This multicentre prospective study included 140 patients from five French medical centres. We assessed patients before surgery (T1), 3 months after surgery (T2), and 12 months after surgery (T3). We assessed the severity of the orofacial deformity, physical, psychological, social, and environmental QoL (WHOQOL-BREF), and depression and anxiety (GHQ-28). Risk factors for poorer outcome were identified using linear mixed models. Between baseline and 12 months, there was significant improvement in psychological and social QoL and in depression (although below the norms reported in the general population), but not in anxiety. Physical QoL was poorer in patients who were younger, who had a mild orofacial deformity, and who were depressed. Psychological QoL was poorer in younger patients and in depressed patients. Social QoL was poorer in patients who were single, who had a mild orofacial deformity, and who were depressed. Although orthognathic surgery provides a moderate improvement in psychological and social QoL, the systematic screening and treatment of depression could further improve QoL after surgery because it is a major predictor of poor QoL in this population.

[Improving the esthetic results and patient satisfaction in orthognatic surgery]. / Améliorer le résultat esthétique et la satisfaction du patient en chirurgie orthognatique.

The objectives of dental and maxillary defect management have changed over the last decade. Occlusal improvement is required, but it is expected to come with a good esthetic result for patients, especially for adults, and mentioned or not preoperatively. Thus, the maxillofacial surgeon must include complementary data in his therapeutic scheme, beyond the one provided by the cephalometric analysis. This chapter was drafted in pluridisciplinary mode to this end. A psychological approach and post-operative satisfaction are crucial factors that were studied prospectively (MD Battini and Courtois) and are a part of this chapter. Esthetic labial standard are also described, based on the results of a retrospective study (MD Hardy, Laure and Goga). Doctor Belhaouari presents solutions to embellish lips with filling products, initially or later. Finally, the complementary surgical techniques that can be used during orthognatic surgery are listed: lipofilling, rhinoplasty, surgery of mandibular angles, apposition of piriform aperture.
