Simultaneous Surgical Correction of Skeletal Class III Dentofacial Deformity During Acute Management of Facial Fractures

Skeletal Class III malocclusions are caused by maxillary deficiency, mandibular protrusion, or a combination of the two. This patient, in this case, may have a sunken in face, strong chin appearance. Most persons with Class III malocclusions, which is a dentofacial deformity, show combinations of skeletal and dentoalveolar components. Orthodontic therapy is usually aimed at compensating for the underlying mild-moderate skeletal Class III discrepancy and patients with severe skeletal Class III discrepancies require a combination of orthodontic treatment and orthognathic surgery to correct the underlying skeletal pattern. By considering many factors, the orthodontic treatment can be done on mild to severe skeletal Class III. These factors are facial profile, dental relationship and skeletal pattern. Those factors should be considered a starting point in making a treatment decision. They give the limitation of orthodontic treatment in terms of whether the occlusion could be corrected, or whether the deformity could be camouflage.

Nasal Changes

Abstract Objective: To quantify the changes in the nose after bimaxillary surgery to correct skeletal Class III malocclusion and to test the hypothesis that there is no change in the nasal width following bimaxillary surgical correction of skeletal Class III when a nasal cinch is properly used. Materials and Methods: Sixty-five adult Korean skeletal Class III patients who had received maxillary advancement/impaction and mandibular set-back surgery in conjunction with an alar base cinch suture were evaluated. The anthropometric variables of the nasal region were measured directly on the soft-tissue surface before and 6 months after surgery. Results: After surgery, the alar width and alar base width had increased significantly (P < .001), while the nasal tip projection decreased (P < .001). The nostril morphology also showed widening (P < .001). There was a trend for females with a narrow alar width presurgically to have a larger amount of nasal widening compared with those with a broader alar width (P < .05). Conclusion: There is a high probability of nasal and nostril widening after bimaxillary surgery for skeletal Class III malocclusion in Koreans despite the careful performance of alar cinch suture. Nevertheless, the authors believe that alar cinch suture was positive in limiting the nasal widening to the minimum and would consider routine application during bimaxillary surgery for skeletal Class III especially for female patients with a narrow nose who are susceptible to these changes.

Dental Compensation

ABSTRACT Introduction: Class III malocclusions are some of the most difficult occlusal anomalies to be treated. Some patients with this condition may require orthognathic surgery, while others may be treated with dental camouflage. Proper patient assessment and selection remains critical in order to achieve favorable results. Objectives: This report outlines the case of an 18-year-old male who sought retreatment for a severe skeletal Class III dentofacial deformity after undergoing orthodontic camouflage treatment involving mandibular arch extractions. A treatment plan comprising dental decompensation and orthognathic surgery was implemented in order to achieve optimal facial and occlusal results. Results: After 28 months of treatment, skeletal and dental correction was achieved and facial features were significantly improved. The orthognathic surgery required a 20-mm sagittal maxillomandibular skeletal correction, combined with a 4-mm correction of the midlines and a 2-mm impaction of the maxilla. Conclusion: Dental compensation may be a risky treatment alternative for severe dentoskeletal discrepancies. In these patients, orthodontics combined with orthognathic surgery is the recommended treatment option.
