Abstract: Objective    To reconstruct the skull base and neck of children and create three-dimensional visual model.    Methods    The digital anatomical image dataset of a 6-year-old Chinese boy was obtained by freezing numerical control milling and digital photography. The cross sections from the skull base to the upper edge of T1 were selected and manually  segmented by using PhotoShop.2021. The Digihuman Reconstruction System was used to directly reconstruct the manually segmented structure, and then imported into 3-Matic Research 13.0 software for adjustment and modification.   Results   The first three-dimensional visualization model of skull base and neck of a Chinese boy was established successfully. The three-dimensional morphology and spatial position of the segmented structures were clearly explained in multiple directions and multi-angles. And detailed observation of skull base, vertebrae, blood vessels, nerves and muscles of neck was completed. The anatomical characteristics and surgical precautions were preliminarily analyzed by measuring carotid and venous nerves and vertebral body data.   Conclusions   The three-dimensional visualization model of skull base and neck of digital children can display the detailed anatomical structure and adjacent relationship, which provides important reference for clinical diagnosis and treatment, virtual surgery and medical teaching of pediatrics.
