Summary: Surgical correction of dentofacial deformities may produce dramatic results. It is essential that a thorough pre-operative evaluation be performed. Therefore a close working relationship between the oral and maxillofacial surgeon and the orthodontist is essential, however consultation with other professionals is mandatory. Among these are the general dentist, family physician, psychologist, speech clinician and myofunctional therapist. An overview of orthognathic surgery has been presented in order to familiarize the myofunctional clinician with these procedures, so that functional patterns both prior to and after surgical repositioning can be properly evaluated and treated.

INTRODUCTION: A conventional ortho-surgical treatment, although with good clinical results, does not often achieve the desired functional outcomes. Patients with dentofacial deformities, especially those with increased occlusal planes (OP), are also affected by muscle, joint and breathing functional disorders, as well as facial esthetic involvement. The surgical manipulation of the OP in orthognathic surgery is an alternative to overcome the limitations of conventional treatment. OBJECTIVE: To report the importance of assessing the occlusal plane during diagnosis, planning and ortho-surgical treatment of patients with facial skeletal deformities and its main advantages. CONCLUSION: Although both philosophies of ortho-surgical treatment (conventional and by surgical manipulation of the OP) have presented good results, the selective correction of the OP allows a full treatment of these patients, providing better esthetic and functional results.

The decision on whether starting an orthosurgical treatment depends on the negative esthetic, functional and social impact the dentofacial deformity has on the quality of life of each patient. The objective of this article is to demonstrate the importance of assessing the quality of life of these individuals by means of applying specific questionnaires before treatment onset in order to increase the success rate of orthosurgical treatment. These questionnaires assess not only the esthetic factor, but also the functional conditions that may be affected as well as the psychological issues related to self-esteem and sociability, all of which must be assessed in order to enable the development of an individual treatment plan that meets patient's expectations. Thus, a more predictable level of satisfaction can be achieved at treatment completion, not only from a normative standpoint stated by professionals, but also from a subjective standpoint stated by patients. Although not enough comparable data is available in the literature for us to assess the extent of improvements produced by orthosurgical treatment, a few recent reports conducted by different universities around the world reveal a good response from the majority of patients after surgery, demonstrating great satisfaction with regard to esthetic, functional and psychosocial factors. Therefore, it is reasonable to conclude that the current objective of orthodontic treatment associated with orthognathic surgery consists not only in treating the esthetic functional components of dentofacial deformities, but also in considering patients' psychological factor.

BACKGROUND: There is a scarcity in the published literature which evaluates the postoperative inflammatory response and patients’ immunity following orthognathic surgery. AIM: The present prospective study aimed to evaluate the changes in two immunological callipers to measure the traumatic effect of orthognathic surgery METHODS: In the present prospective cohort study, we included women (age range 16-30 years) with severe dentofacial deformities who were scheduled for bimaxillary osteotomy. Blood samples were collected for measurement of transforming growth factor beta one (TGF-β1) and osteoprotegrin (OPG) levels. The statistical analysis was carried with SPSS software. RESULTS: In the present study, nine patients with severe dentofacial deformity were operated successfully under general anaesthesia. All patients reported decreased energy and fatigue in the early days after surgery and had difficulties with nutrition due to pain, oedema and paresthesia; however, no massive weight loss was reported. The levels of OPG started to increase immediately postoperatively (mean = 0.46 ± 0.08; p = 0.001). A significant increase in the concentration of OPG begun postoperatively and continued to rise significantly until the six weeks to reach 2.24 ± 0.30 ng/mL (p < 0.001). Similarly, the concentration of TGF-β1 increased at three days postoperatively and continued to rise until the six weeks to reach 1.28 ± 0.19 ng/mL (p <0 .001). CONCLUSION: In conclusion, orthognathic surgery is associated with a significant rise in the pro-inflammatory cytokines until the six weeks postoperatively. These observed results may indicate a significant alteration in the immunity of the patients to undergoing orthognathic surgery.

Abstract Objective Prevalence of silent obstructive sleep apnea (OSA) in patients with dentofacial deformities is unknown, although OSA is severe risk of airway obstruction in perioperative orthognathic surgery or complication after surgery. The aim of this study was to investigate prevalence and risk factors of silent OSA in patients with dentofacial deformities. Methods We analyzed 72 patients (24 male, 48 female) with dentofacial deformities without previous OSA symptoms. Polysomnography was performed before orthognathic surgery. Prevalence and risk factors of silent OSA were statistically analyzed as related to Apnea hypopnea index (AHI). Results Mean AHI was 1.6 (range: 0-12.1) /h. Three patients of 72 patients (4.1%) were diagnosed silent OSA. AHI during REM sleep phase 3.7 (0-32.3) was higher than AHI during NREM sleep phase 1.0 (0-9.7). AHI of male patients was higher than that of female. AHI was increased according to high BMI. AHI was higher in deep bite than open bite, edge to edge bite and nomal bite. AHI of mandibular asymmetry cases were higher than that of symmetry cases. Conclusions The prevalence of silent OSA was 4.1%. Obesity, male, deep bite, mandibular asymmetry and REM sleep phase were risk factors of silent OSA.
