  • oral and dental restoration of wide alveolar cleft using Distraction Osteogenesis and temporary anchorage devices
    Journal of Cranio-maxillofacial Surgery, 2013
    Co-Authors: Adi Rachmiel, Omri Emodi, Zvi Gutmacher, Israel Blumenfeld, Dror Aizenbud
    Abstract:

    Abstract Closure of large alveolar clefts and restoration by a fixed bridge supported by implants is a challenge in cleft alveolus treatment. A major aesthetic concern with Distraction Osteogenesis is obtaining a predictable position of the implant in relation to the newly generated bony alveolar ridge. We describe the treatment of a large cleft alveolus and palate reconstruction by Distraction Osteogenesis utilizing temporary anchorage devices (TADs) followed by a fixed implant-supported bridge. The method consists of segmental bone transport by Distraction Osteogenesis using a bone-borne distractor to minimize the alveolar cleft, followed by closure of the residual small defect by bone grafting three months later. During the active transport Distraction, TADs were used exerting multidirectional forces to control the Distraction vector forward and laterally for better interarch relation. A vertical alveolar Distraction of the newly reconstructed bone of 15 mm facilitated optimal implant placement. The endosseous implants were osteointegrated and supported a fixed dental prosthesis. In conclusion, the large cleft alveolus defect was repaired in three dimensions by Distraction Osteogenesis assisted by TADs, and the soft tissues expanded simultaneously. Endosseous implants were introduced in the newly reconstructed bone for a fixed dental prosthesis enabling, rehabilitation of aesthetics, eating and speaking.

  • treatment of maxillary cleft palate Distraction Osteogenesis vs orthognathic surgery
    annals of maxillofacial surgery, 2012
    Co-Authors: Adi Rachmiel, Michal Evenalmos, Dror Aizenbud
    Abstract:

    Purpose: The purpose of this paper is to compare the treatment of hypoplastic, retruded maxillary cleft palate using Distraction Osteogenesis vs. orthognathic surgery in terms of stability and relapse, growth after Distraction and soft tissue profile changes. th Materials and Methods: The cleft patients showed anteroposterior maxillary hypoplasia with class III malocclusion and negative overjet resulting in a concave profile according to preoperative cephalometric measurements, dental relationship, and soft tissue analysis. The patients were divided in two groups of treatment : S0 eventeen were treated by orthognathic Le Fort I osteotomy fixed with four mini plates and 2 mm screws, and 19 were treated by maxillary Distraction Osteogenesis with rigid extraoral devices (RED) connected after a Le Fort I osteotomy. The rate of Distraction was 1 mm per day to achieve Class I occlusion with slight overcorrection and to create facial profile convexity. Following a 10 week latency period the Distraction devices were removed. Results: In the RED group the maxilla was advanced an average of 15.80 mm. The occlusion changed from class III to class I. The profile of the face changed from concave to convex. At a 1-year follow up the results were stable. The mean orthognathic movement was 8.4 mm. Conclusion: In mild maxillary deficiency a one stage orthognathic surgery is preferable. However, in patients requiring moderate to large advancements with significant structural deficiencies of the maxilla or in growing patients the Distraction technique is preferred.

  • Distraction Osteogenesis for tracheostomy dependent children with severe micrognathia
    Journal of Craniofacial Surgery, 2012
    Co-Authors: Adi Rachmiel, Omri Emodi, Samer Srouji, Dror Aizenbud
    Abstract:

    AbstractObstructive sleep apnea (OSA) in pediatric populations is often associated with congenital craniofacial malformations resulting in decreased pharyngeal airway, which in severe cases leads to tracheostomy dependence. The purpose of this study was to use Distraction Osteogenesis to improve the

  • outcomes analysis of mandibular Distraction Osteogenesis for the treatment of pierre robin sequence
    Plastic and Reconstructive Surgery, 2013
    Co-Authors: Kariuki P Murage, Sunil S Tholpady, Michael T Friel, Robert J Havlik, Roberto L Flores
    Abstract:

    UNLABELLED Mandibular Distraction Osteogenesis is an established technique used to treat infants with Pierre Robin sequence associated with severe airway obstruction. The authors present a 7-year retrospective review of all patients with Pierre Robin sequence treated with mandibular Distraction Osteogenesis. Recorded variables included improvements in apnea/hypopnea index and postintervention tracheostomy. Multiple preoperative variables were assessed for association with successful mandibular Distraction Osteogenesis or tracheostomy. Fifty patients were identified for this study. Four patients (8 percent) required tracheostomy after Distraction. A Fisher's exact test demonstrated no statistical association of tracheostomy with prematurity, low birth weight, preoperative intubation, late intervention, genetic syndromes, cardiac abnormalities, pulmonary abnormalities, or gastrostomy tube. The absence of a cleft palate, gastroesophageal reflux disease, and need for Nissen fundoplication were associated with failure of Distraction. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.
