1/7. Mandibular distraction osteogenesis with multidirectional extraoral distraction device in hemifacial microsomia patients: three-dimensional treatment planning, prediction tracings, and case outcomes.Distraction osteogenesis of the craniofacial skeleton with the use of several different types of distraction devices (i.e., extraoral, intraoral, unidirectional, multidirectional, and customized) have been documented. However, the details of treatment planning and the method of predicting the distraction of the mandible in patients with hemifacial microsomia have not been published previously. This paper presents a technique for (1) three-dimensional treatment planning for mandibular distraction, (2) three-dimensional prediction tracings with conventional radiographs (panoramic, lateral, and posterior-anterior cephalometric), and (3) correlating the treatment planning and clinical applications. Lastly, 2 patients with hemifacial microsomia planned and treated with this approach are reported.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
2/7. Oro-dental and craniofacial anomalies in leopard syndrome.'leopard syndrome' is a syndrome affecting many systems or organs. The main anomalies are summarized in the acronym LEOPARD in which each letter corresponds to the damage of a given organ. In the presented case, there are oro-dental and craniofacial anomalies. The relationship between the leopard syndrome and the given anomalies and the possibilities of the management and the follow-up of the diseased are studied. The clinical case presented is a 4-year-old boy with leopard syndrome showing retardation of dental development, delayed development and possible agenesis of permanent teeth, and craniofacial anomalies (osseous hypodevelopment). The bibliographical study shows that leopard syndrome is due to damage of the neural crest cells. Thus, the dental and craniofacial anomalies arise since neural crest cells participate in the formation of the teeth and some craniofacial bones. Therefore, dental and craniofacial anomalies might be expected in some cases of the disease. The therapeutic management of the lesions, and the follow-up of the patient would be done by a multidisciplinary team.- - - - - - - - - - ranking = 9keywords = craniofacial (Clic here for more details about this article) |
3/7. Fibrous ankylosis after distraction osteogenesis of a costochondral neomandible in a patient with grade III hemifacial microsomia.Distraction osteogenesis has recently become a mainstay for treatment of craniofacial syndromes with mandibular hypoplasia. This article presents the difficult case of a patient with a previous costochondral rib graft who underwent mandibular distraction and developed a fibrous pseudoarthrosis at the distraction site. This was attributed in part to an associated temporomandibular joint ankylosis. Resorption of the pseudoarthrosis occurred once the distractor was removed. It appears that distraction osteogenesis of a mandible with an ankylosed temporomandibular joint can result in healing with a fibrous union, presumably because of movement at the distraction site when masticating. This can result in a pseudo "temporomandibular joint" at the distraction site. A temporomandibular joint arthroplasty was performed, followed by repeat distraction. We conclude that if there is an ankylosed temporomandibular joint or a stiff temporomandibular joint that may ankylose during the course of the distraction process, then a temporomandibular joint arthroplasty should be performed before or at the time the distractor is placed.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
4/7. Stereolithography for craniofacial surgery.Advances in computer technology have aided in the diagnostic and clinical management of complex congenital craniofacial deformities. The use of stereolithographic models has begun to replace traditional milled models in the treatment of craniofacial deformities. research has shown that stereolithography models are highly accurate and provide added information in treatment planning for the correction of craniofacial deformities. These include the added visualization of the complex craniofacial anatomy and preoperative surgical planning with a highly accurate three-dimensional model. While the stereolithographic process has had a beneficial impact on the field of craniofacial surgery, the added cost of the procedure continues to be a hindrance to its widespread acceptance in clinical practice. With improved technology and accessibility the utilization of stereolithography in craniofacial surgery is expected to increase. This review will highlight the development and current usage of stereolithography in craniofacial surgery and provide illustration of it use.- - - - - - - - - - ranking = 11keywords = craniofacial (Clic here for more details about this article) |
5/7. Freeman-Sheldon syndrome: a case report.BACKGROUND: Freeman-Sheldon Syndrome is a rare craniofacial syndrome that has not been described in the dental literature to date. The main feature of relevance is severe microstomia, which limits access for routine dental care. CASE REPORT: Dental treatment was carried out successfully under local anaesthetic for a young child with Freeman-Sheldon syndrome. A novel coloured compomer material was helpful in the management of the case. CONCLUSION: The importance of early referral of children with rare craniofacial anomalies to Specialist Paediatric Dental services is highlighted.- - - - - - - - - - ranking = 2keywords = craniofacial (Clic here for more details about this article) |
6/7. Nonlethal case of otocephaly and its implications for treatment.Otocephaly is a craniofacial syndrome with a constellation of findings consistent with symmetrically deficient development of the first branchial arch. Characteristically, those affected have ventrally displaced ears, microstomia, and an atrophic to absent mandible. Secondary to oropharyngeal incompetence, ventilatory, difficulties typically lead to the imminent death of these infants shortly after birth. Here we present a patient who survived well beyond the perinatal period with the support of pediatric intensivists and advanced technology available for the diagnosis and treatment of such a complex crajniofacial syndrome.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
7/7. Controlled multiplanar distraction of the mandible: device development and clinical application.Distraction osteogenesis has been shown to be an effective method of lengthening and augmenting endochondral bone. It has also been applied effectively in the reconstruction of the membranous bones of the craniofacial skeleton. With the accumulation of clinical experience in mandibular distraction, the differences between endochondral and membranous bone distraction have become apparent, especially in the limitations of uniplanar distraction for the three-dimensional reconstruction of the deficient mandible. Distraction of the mandible in a single plane cannot satisfy fully the functional and structural requirements of the patient with malocclusion as well as deficiency of the skeletal and soft tissue. This study reports the development and clinical use of a multiplanar mandibular distraction device with the ability to achieve linear distraction (Z-plane or sagittal), angular distraction (Y-plane or vertical), and transverse distraction (X-plane or coronal). The device contains two independent gear arrangements attached to two arms that extend from the central unit. Therefore, the trajectory of the regenerated bone may be changed during the distraction process. The device also allows manipulation of the various planes of movement independent of each other. Furthermore, the rotational points for the multiplanar distraction devices are located at a single point; therefore only a single osteotomy and two pin sites are required. The multiplanar distraction device allows the surgeon to customize and contour the dimensions of the distraction process by controlling the trajectory of the translation of the regenerated bone.- - - - - - - - - - ranking = 1keywords = craniofacial (Clic here for more details about this article) |
