ABSTRACT Dentofacial deformities usually are surgically treated, and 3D virtual planning has been used to favor accurate outcomes. Cases reported in the present article show that orthognathic surgery carried out to correct facial asymmetries does not comprise only one treatment protocol. 3D virtual planning might be used for surgical planning, but it should also be used to diagnose the deformity, thus allowing for an analysis of the best-recommended possibilities for the orthodontic preparation that suits each individual case.

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.

Facial asymmetry, following early childhood condylar trauma, is a common complaint among patients who seek surgical treatment. G.D.M., a 27-year-old male patient, sought professional help to correct his cosmetic flaw, caused by a condylar fracture when he was 8-years-old. After the proper orthodontic treatment, he underwent a double jaw orthognathic surgery and, 9 months later, a second one to correct the remaining asymmetry. Two years after this second procedure, the patient is still under surveillance and has no complaints.

Abstract Facial asymmetry is a condition that compromises function and social interactions and, consequently, the quality of life. Orthodontic-surgical treatment may be indicated to achieve a stable occlusion and significant improvement in facial aesthetics. The virtual planning of the maxillary, mandibular and chin movements can be done prior to surgery. These movements can be successfully performed with the use of prototyped guides obtained from virtual planning. The aim of this article is to show the state of the art of treatments of facial asymmetries, and emphasize how important is the multi-disciplinary approach to achieve predictable aesthetic and functionally stable results in a patient with facial asymmetry and chin protrusion.

Objective: The aim of this qualitative study was to analyze the content of posts on Twitter in order to gain an in-depth understanding of patients’ thoughts and experiences surrounding orthognathic surgical treatment. Materials and Methods: Using the Twitter search function, with the keywords “jaw surgery,” the 1,000 most recent posts on Twitter with relevance to a combined orthodontic and orthognathic surgical treatment were extracted. After applying relevant inclusion and exclusion criteria, the selected posts were analyzed using thematic analysis by 2 independent investigators. Distinct themes and subthemes were developed. Results: A total of 689 posts were analyzed; the 3 main themes identified in relation to orthognathic surgery were preoperative engagement, postoperative difficulties, and posttreatment satisfaction. Twelve subthemes were also identified, expressing issues such as anticipation or apprehension of the surgical procedure, postoperative pain and edema, dietary restrictions and weight loss, paresthesia, depression, and satisfaction with improvements in appearance and self-confidence. The 6 terms most frequently used in tweets were “recovery,” “braces,” “swollen,” “eat,” “liquid diet,” and “pain.” Conclusions: The findings from the present study can increase the awareness of clinicians involved in the combined orthodontic and orthognathic surgical treatment of patients with dentofacial deformities, allowing them to better educate and counsel their patients throughout the entire treatment process.

Orthognathic surgery describes the surgical movement of the mandible and maxilla to correct dentofacial deformities that result from congenital or traumatic etiologies. Patients with dentofacial deformity often have malocclusion and functional problems related to breathing, chewing, or speech articulation. Furthermore, facial asymmetries or disproportions resulting from dentofacial deformities can adversely affect the psychosocial health of the patient. The goal of orthognathic surgery is to improve both function and form beyond what can be achieved with orthodontic or medical treatments. Some of the most commonly performed orthognathic surgery procedures include Le Fort I osteotomy of the maxilla, bilateral sagittal split osteotomy of the mandible, and genioplasty. Successful outcome after orthognathic surgery should be judged by achieving an improved dental occlusion, enhanced facial aesthetics, and open upper airway. A number of studies have shown that orthognathic surgery leads to significant improvements in the quality of life of patients with dentofacial deformities. Orthognathic surgery also has a significant impact on the upper airway. In patients with severe obstructive sleep apnea, maxillomandibular advancement has the potential to lead to dramatic improvements in the apnea-hypopnea index and lowest oxygen saturation value. With careful surgical planning and execution, consistent outcomes can be expected.   This review contains 17 figures, 4 tables, and 32 references. Key Words: aesthetic surgery, dentofacial deformity, genioplasty, Le Fort I, malocclusion, orthognathic surgery, sagittal split osteotomy of the mandible, sleep apnea, virtual surgical planning

Abstract Background The elaboration of a precise pre-surgical plan is essential during surgical treatment of dentofacial deformities. The aim of this study was to evaluate the accuracy of computer-aided simulation compared with the actual surgical outcome, following orthognathic surgery reported in clinical trials. Methods Our search was performed in PubMed, EMBASE, Cochrane Library and SciELO for articles published in the last decade. A total of 392 articles identified were assessed independently and in a blinded manner using eligibility criteria, out of which only twelve articles were selected for inclusion in our research. Data were presented using intra-class correlation coefficient, and linear and angular differences in three planes. Results The comparison of the accuracy analyses of the examined method has shown an average translation (< 2 mm) in the maxilla and also in the mandible (in three planes). The accuracy values for pitch, yaw, and roll (°) were (< 2.75, < 1.7 and < 1.1) for the maxilla, respectively, and (< 2.75, < 1.8, < 1.1) for the mandible. Cone-beam computed tomography (CBCT) with intra-oral scans of the dental casts is the most used imaging protocols for virtual orthognathic planning. Furthermore, calculation of the linear and angular differences between the virtual plan and postoperative outcomes was the most frequented method used for accuracy assessment (10 out of 12 studies) and a difference less than 2 mm/° was considered acceptable and accurate. When comparing this technique with the classical planning, virtual planning appears to be more accurate, especially in terms of frontal symmetry. Conclusion Virtual planning seems to be an accurate and reproducible method for orthognathic treatment planning. However, more clinical trials are needed to clearly determine the accuracy and validation of the virtual planning in orthognathic surgery.

Aim Acceptable facial aesthetics is a common desire among patients presenting with dentofacial deformities planning to undergo orthognathic surgeries. Thus, professionals must be alert to their patients’ complaints as well as their desires regarding facial morphology, because this is quite subjective and personal. This research aimed at evaluating the different views of orthodontists and oral maxillofacial surgeons regarding the facial analysis of patients who undergo orthognathic surgery. Methods Thirty individuals were selected with a minimum postoperative period of 6 months and photographed in the frontal and profile norm. Facial morphology characteristics were recorded to observe the agreement of the assessments of four professionals (two orthodontists and two surgeons). Results A significant agreement was seen between the orthodontists regarding the nasolabial angle (80%). In the frontal analysis, the agreement percentage (60%) between orthodontists and surgeons was considerable regarding facial asymmetry assessment. Conclusions Professionals must keep alert to facial analysis, especially in terms of tegumental harmony, for the orthognathic surgery to reestablish, satisfactorily, the facial aesthetics in all parameters set.
