RESUMO
The aim of the study was to apply an effective treatment protocol with low morbidity for children with syndromic and nonsyndromic micrognathia using curvilinear distractors, intraoral approach and early orthodontic treatment. We report 7 patients aged from 3 to 13 years with bilateral mandibular hypoplasia. These patients were characterized by severe malocclusion, esthetic facial deformation and respiratory disorders. In 3 patients mandibular hypoplasia was combined with anterior open bite. The intraoral surgical approach was used in all cases. Good functional and esthetic results were achieved during treatment. The less traumatic intraoral approach, curvilinear distractors, ultrasound callus formation control and early orthodontic treatment assure the good functional and esthetic results in severe cases facilitating the continuinty in complex rehabilitation of the growing child.

Microstomia presents a unique challenge to the patient. Patients with microstomia who must wear removable dental prostheses often face the difficulty of being unable to insert or remove the prosthesis because of the constricted opening of the oral cavity. A completely edentulous patient, who developed microstomia along with Raynaud's phenomenon induced by scleroderma, is presented. This clinical report describes a quick and easy method for fabrication of a sectional custom impression tray connected by press button and a sectional complete denture retained by magnets. A sectional denture that provides ease in placement and removal can be successfully used in clinical practice for treatment of microstomia patients.

Pierre Robin syndrome is characterized by the triad: micrognathia, cleft palate and glossoptosis. This syndrome, which often undermines several organs and systems, is treated with a multidisciplinary approach that involves several specialists. The AA. present a case of Pierre Robin syndrome in neuromuscular rehabilitation by physiotherapy EMG-assisted.

Micrognathia complicated by edentulous maxilla was treated by performing sagittal-split mandibular osteotomy and immobilizing a subperiosteal implant using transmaxillary screws. The patient was a 42-year-old man who had a birdlike facial deformity caused by significant hypoplasia of the mandible. He also demonstrated significant malocclusion attributable to micrognathia and edentulous maxilla caused by resorption of the alveolar bone. These conditions impaired his mastication and articulation, making it impossible for him to eat regular food or carry out normal conversation. A subperiosteal implant was placed on the edentulous maxilla, and was rigidly immobilized to the maxilla using five transmaxillary screws. A prosthesis was then attached to the implant, and by using the implant as the point of reference and the anchor, the mandible was moved forward by sagittal-split mandibular osteotomy. Intermaxillary fixation was subsequently performed. The postoperative course has been favorable, and his facial complexion has improved significantly. One and a half years after his surgery, there has been no sign of complications or malocclusion caused by mandibular retraction. He is now able to eat regular food and speak normally.
