Resumen
[EN]A three-dimensional (3D) model of the skull base
was reconstructed from the pre- and post-dissection head CT
images and embedded in a Portable Document Format (PDF)
file, which can be opened by freely available software and
used offline. The CT images were segmented using a specific
3D software platform for biomedical data, and the resulting
3D geometrical models of anatomical structures were used for
dual purpose: to simulate the extended endoscopic endonasal
transsphenoidal approaches and to perform the quantitative
analysis of the procedures. The analysis consisted of bone
removal quantification and the calculation of quantitative pa rameters (surgical freedom and exposure area) of each proce dure. The results are presented in three PDF documents con taining JavaScript-based functions. The 3D-PDF files include
reconstructions of the nasal structures (nasal septum, vomer,
middle turbinates), the bony structures of the anterior skull
base and maxillofacial region and partial reconstructions of
the optic nerve, the hypoglossal and vidian canals and the
internal carotid arteries. Alongside the anatomical model, ax ial, sagittal and coronal CT images are shown. Interactive 3D
presentations were created to explain the surgery and the as sociated quantification methods step-by-step. The resulting
3D-PDF files allow the user to interact with the model through
easily available software, free of charge and in an intuitive
manner. The files are available for offline use on a personal
computer and no previous specialized knowledge in informatics is required.
