Purpose: The aim of this article was to demonstrate a novel approach to designing facial prostheses using the transplantation concept and computer-assisted technology for extensive, large, maxillofacial defects that cross the facial midline. Materials and methods: The three-dimensional 3D facial surface images of a patient and his relative were reconstructed using data obtained through optical scanning. Based on these images, the corresponding portion of the relative's face was transplanted to the patient's where the defect was located, which could not be rehabilitated using mirror projection, to design the virtual facial prosthesis without the eye. A 3D model of an artificial eye that mimicked the patient's remaining one was developed, transplanted, and fit onto the virtual prosthesis. A personalized retention structure for the artificial eye was designed on the virtual facial prosthesis.

With advances in magnetic resonance imaging MRI and molecular biology and the availability of mutant mouse models of human cortical malformations, many malformations of brain development have been reclassified. This chapter addresses malformations seen most often in clinical practice and those malformations that are less common but are distinctive and have a profound impact of early childhood development. The malformations presented here are grouped according to presumed dominant defect in embryologic or fetal development. Diffusion tensor imaging DTI is included in the diagnosis of malformations in which aberrant white matter tracts are a dominant feature. A rudimentary description of relevant embryology is needed. Around 26 to 28 days after conception, the process of neurulation, in which the lateral edges of the neural plate elevate into neural folds, takes place. At the cranial end of the neural tube, the primitive brain vesicles form and include the prosencephalon, mesencephalon, and rhombencephalon.

Associated anomalies include ocular features hypertelorism, microphthalmia, eyelid coloboma , facial clefts, midline defects and microtia. Septo-optic dysplasia, a variable combination of abnormalities of cerebral midline structures, is a clinically heterogeneous syndrome in which the midline defects may be implicated [ncbi. It may also be accompanied by other malformations, including multiple facial dysmorphism, midline defects , cleft lip and palate, musculoskeletal and other non-neurological [ncbi. Prenatal detection of an abdominal wall defect associated with multiple midline defects should alert one to the possibility of OEIS complex and pentalogy of Cantrell and prompt [ncbi.
Do you know anyone in your life who has some of the issues discussed in that video or listed in this article. Large head with overly large eyes sometimes open and a severe cleft palate underdeveloped extremities and almost no tail. Midline birth defects. Back to cleft palate. Numerous reports of ventral developmental defects problems that occur before the baby is born have been described in association with phace syndrome.
