“…Even reconstruction of branching structures or foramina is maintained when alternative software packages are used for interactive data processing (Haas and Fischer, 1997). Export in DXF or STL format to CAD systems will create high-accuracy rapid prototypes (Kermer et al, 1998). A rapid prototyping model could valuably serve for resident education and various surgical exercises to be carried out on the 3D stereophysical model.…”

Evaluation of two 3D virtual computer reconstructions for comparison of cleft lip and palate to normal fetal microanatomy

et al. 2006

Cleft lip and palate reconstructive surgery requires thorough knowledge of normal and pathological labial, palatal, and velopharyngeal anatomy. This study compared two software algorithms and their 3D virtual anatomical reconstruction because exact 3D micromorphological reconstruction may improve learning, reveal spatial relationships, and provide data for mathematical modeling. Transverse and frontal serial sections of the midface of 18 fetal specimens (11th to 32nd gestational week) were used for two manual segmentation approaches. The first manual segmentation approach used bitmap images and either Windows-based or Mac-based SURFdriver commercial software that allowed manual contour matching, surface generation with average slice thickness, 3D triangulation, and real-time interactive virtual 3D reconstruction viewing. The second manual segmentation approach used tagged image format and platformindependent prototypical SeViSe software developed by one of the authors (F.W.). Distended or compressed structures were dynamically transformed. Registration was automatic but allowed manual correction, such as individual section thickness, surface generation, and interactive virtual 3D real-time viewing. SURFdriver permitted intuitive segmentation, easy manual offset correction, and the reconstruction showed complex spatial relationships in real time. However, frequent software crashes and erroneous landmarks appearing "out of the blue," requiring manual correction, were tedious. Individual section thickness, defined smoothing, and unlimited structure number could not be integrated. The reconstruction remained underdimensioned and not sufficiently accurate for this study's reconstruction problem. SeViSe permitted unlimited structure number, late addition of extra sections, and quantified smoothing and individual slice thickness; however, SeViSe required more elaborate work-up compared to SURFdriver, yet detailed and exact 3D reconstructions were created. © 2006 Wiley-Liss, Inc.Key words: lip anatomy; velopharyngeal anatomy; serial sections; 3D reconstruction; 3D triangulation; SURFdriver; SeViSe; real-time viewingThe key to excellent static and functional results in cleft lip and palate (clp) reconstructive surgery lies in detailed knowledge of the normal and pathological labial, palatal, and velopharyngeal anatomy. The current therapeutic concepts of clp treatment aim at functional reconstruction or imitation of normal anatomy, as expounded by Kriens

“…They have been extensively used for designing and manufacturing a prototype in the field of engineering and technology [3,4]. In recent years, stereolithography has been applied to create models of the skull, mandible and ear [5,6]. However, these models are not suited for drilling, since the material is solid plastic.…”

The anatomy of the temporal bone is extremely complicated. If a three-dimensional model could be simulated, it would greatly contribute to the stereoscopic understanding of anatomy and surgery. A simulated three-dimensional model of a human temporal bone was prototyped using the selective laser sintering method. The model could be shaved using a surgical drill in the same way as in real surgery. A magnified model was particularly useful for the instruction of anatomy and surgery. When a translucent area was selected, a bony labyrinth could be created together with an internal auditory meatus and facial nerve, which also contributed to the easy understanding of the inner ear structure. The three-dimensional prototyped model using selective laser sintering serves as a good educational material for middle ear anatomy and surgery.

“…Three dimensional data generated from conventional CT or MRI is guided into a manufacturing device to produce the physical model of the image using special manufacturing software packages. The manufactured stereolithographic biomodels improve the quality and precision of essential diagnostic measurements and is useful for surgical preplanning [25], reconstruction of cranial bone, ear or orbital wall defects [26][27][28], primary reconstruction in craniomaxillofacial trauma surgery [29], and for accurate, preoperative adaptation of reconstruction plates or osteosynthesis devices [30]. Although the use of stereolithography in routine cases is quite rare, it is already used in various places with very satisfactory results especially in severe cases of maxillofacial deformities [12,31].…”

Surgical correction of congenital and acquired facial deformities has transcended the primitive era of using non biologic materials to current attempts at own face growing through biotechnology. A summative account of this trend is still lacking in the literature. The objective of this article is to present an update on current knowledge in the strides to achieve functionally and aesthetically perfect facial reconstruction. It highlights the impact of advancements in 3D imaging, stereolithographic biomodelling, microvascular surgical tissue transplantation and tissue biotechnology in the surgical efforts to solve the problems of facial disfigurement whether congenital or acquired.
