Orthognathic surgery 1. Orthognathic surgery Dr. Mohamed Rahil ((Maxillofacial surgeon)) Tikrit dentistry college 2015 - 2016 2. Orthognathic surgery is the art and science of diagnosis, and treatment of facial disproportion. These disproportion may be congenital or aquired 3 In general, orthognathic surgery to reposition the maxilla, mandible, or chin is the mainstay treatment for patients who are too old for growth modification and for dentofacial conditions that are too severe for either surgical or orthodontic camouflage Orthognathic surgery to correct these discrepancies can involve a range of surgical movements, which achieve repositioning of the maxilla or mandible within the facial skeleton . Surgery of this kind does not affect any inherent growth capacity that may reside in the jaws and for this reason it is only carried out once skeletal growth has ceased, in the adult

  1. WHY ORTHOGNATHIC SURGERY? 1.When orthodontic treatment alone cannot correct a problem. 2.To improve jaw function. 3.To enhance the long term orthodontic result (stability). 4.Reduction in overall treatment time. 5.Change in facial appearance. 6.Improved breathing. 7.Improved speech. 8.Improvement in jaw pain. 10
  2. American surgeons modify the technique for maxillary surgery that has been developed in europe Epker, bell and wolford developed lefort-1 maxillary downward fracture ,so that we can keep the maxilla stable in all 3 planes of spaces. By 1980 progress has reached such an extent to reposition either or both the jaws to move chin in all 3 planes of spaces. Rigid internal fixation made it possible for comfort and better immobilization was achieved

  7. Even though maxillary surgery requires knowledge of the anatomical variations of the facial sinuses, 15 the literature is still scarce regarding the effects of orthognathic surgery on the MS. 2,4,6 Thus, the aim of this study was to assess the changes in the MS and PAS after bimaxillary surgery using cone-beam computed tomography (CBCT). The null hypothesis was that bimaxillary surgery would not change the MS and PAS dimensions

Once the osteotomy hs been completed, a prefabricated inter-occlusal wafer splint is placed. Then we perform an inter-maxillary fixation with three wire ligatures. The two bony segments should fit passively together without a gap. If they were made to fit un passively, TMJ problems would result postoperatively Orthognathic surgery is performed by maxillofacial or an oral surgeon or a plastic surgeon in collaboration with an orthodontist. It often includes braces before and after surgery, and retainers after the final removal of braces. Orthognathic surgery is often needed after reconstruction of cleft palate or other major craniofacial anomalies. Careful coordination between the surgeon and orthodontist is essential to ensure that the teeth will fit correctly after the surgery These patients had no craniofacial cleft history and were candidates for orthognathic surgery in Maxillofacial Surgery Department of Qaem Hospital of Mashhad (Iran), 2015 to 2017. All of the operations were carried out or supervised by a single surgeon and anesthesiologist using the same protocol The goals of minimally invasive surgery are to reduce tissue trauma and to minimize bleeding, edema, and injury, thereby improving the rate and quality of healing. In orthognathic surgery, there are two minimally invasive techniques that can be used separately or in combination: (1) endoscopic exposure and (2) distraction osteogenesis The orthognathic surgical procedures may include maxillary or mandibular surgery, or both. Concomitant intranasal surgery with septoplasty and reduction of the inferior turbinate may be required to improve nasal airflow dynamics. Genioplasty and neck liposuction may also be considered in select patients to improve the overall aesthetic outcome

  1. Benefit of cephalograph in orthognathic surgery Cephalometric analysis helpful in establishing the relation of: • The maxilla and mandible to the base of skull. • The maxilla to mandible. • The maxillary teeth to maxilla. • The mandibular teeth to mandible. • The upper incisors to lower incisors
  2. Nine studies that evaluated this outcome in a sample 2078 patients were summarized2,14,21-23,26,29-31Overall, on- ly 177 patients (8.5%) experienced some form of complication. Given retro- spective design theincluded studies, this might be considered an underestima- tion
  3. At each appointment, the surgeon must evaluate the patient's ability to perform adequate oral hygiene and wound care and should provide additional instructions if necessary. Postoperatively, patients will have to follow three basic instructions: 1. Diet In orthognathic surgery the internal fixation devices usually do not allow for full.

Orthognathic Surgery (Corrective Jaw Surgery) is a complex surgery and because of the intricacies of occlusion (the way the teeth bite) and the combined effect on the facial appearance when moving the teeth and jaws, orthognathic surgery must be carefully planned. Because of its complexity, a team approach is used Corrective jaw surgery, or orthognathic surgery, is performed by Oral and Maxillofacial Surgeons to correct a wide range of minor and major skeletal and dental irregularities, including the misalignment of jaws and teeth, which, in turn, can improve chewing, speaking and breathing Abstract. Vertical maxillary excess (VME) may be defined as excessive maxillary development in the vertical plane. Patients with VME tend to exhibit a predominantly vertical facial growth pattern, sometimes termed a tall face deformity.
