Mandibular distraction osteogenesis (MDO) is currently an accepted method of treatment for patients requiring reconstruction of hypoplastic mandibles. To date one of the unsolved problems is how to assess the quantitative increase of mandible length needed to achieve a significant change in the volume of the posterior airway space (PAS) in children with mandibular micrognathia following distrac...

The purpose of this study was to develop an improved technique of alveolar ridge augmentation by distraction osteogenesis using distraction screws, and to investigate tissue reactions to titanium implants at the distraction site. The left mandibular premolars were extracted from 6 adult dogs. After 12 weeks, a box-shaped osteotomy of the alveolar bone was carried out, and distraction devices we...

PURPOSE This report presents the results of distraction osteogenesis using unidirectional extraoral and intraoral devices in 8 patients with different grades of vertical mandibular ramus hypoplasia. PATIENTS AND METHODS Eight patients with hypoplastic mandibles underwent unilateral lengthening of the ascending ramus using unidirectional extraoral or intraoral devices. Intraoral mandibular dis...

OBJECTIVE Posterior vault remodeling by distraction osteogenesis is a relatively new technique used for initial correction of turribrachycephaly in children with bicoronal craniosynostosis. We present a new potential complication from this procedure; a case of pan-suture synostosis subsequent to posterior vault distraction. METHODS We report an infant girl who presented with bicoronal synosto...

OBJECTIVE Distraction osteogenesis is a well-accepted technique in the treatment of patients with hypoplastic craniofacial components. Complications of distraction osteogenesis are well described in the literature. We describe a complication of using an external distraction device in a 9-year-old girl with Pfeiffer. INTERVENTION AND RESULTS A modified Lefort III osteotomy was performed for ma...

OBJECTIVE Distraction osteogenesis is an alternative treatment method for the correction of mandibular hypoplasia. In this case report, distraction with a multidirectional extraoral device was performed to gradually lengthen the corpus and ramus of a patient who had a severe hypoplastic mandible. MATERIALS AND METHODS The patient underwent bilateral extraoral ramus and corpus distraction oste...

In this study the literature dealing with various aspects of two different surgical treatment modalities i.e. distraction osteogenesis and conventional orthognathic surgery were reviewed. The keywords used were distraction osteogenesis; conventional orthognathic surgery; cleft lip and palate; velopharyngeal insufficiency; speech; stability; relapse; complications; quality of life. Apart from th...

BACKGROUND Historically, surgical treatment of children with a delayed presentation of cranial synostosis required complex cranial vault reconstruction. Recently, less invasive options for surgical correction, such as internal distraction osteogenesis, have been explored. In this study, we describe the successful management of delayed presentation of sagittal synostosis using distraction osteog...
