Project Description

This surgical animation depicts step-by-step instructions of the pterional approach starting from patient positioning and ending at craniotomy. Because there are many versions of the pterional approach with illustrations that only focus on key points, such illustrations may not be adequate for teaching residents nuances in practice. This animation provides detailed explanations of how instrument technique and hardware placement can enhance the safety of the procedure. Each surgical instrument is specific to the client’s current practice and is carefully animated to follow their techniques; The angle and direction of each blade, the alternating use of the curved Metzenbaum scissors to cut and dissect, and the rotation of the broad periosteal dissector are all examples of such.  Simple textures are used to isolate anatomic structures by eliminating unnecessary detail. The combination of insets and superimposed anatomy aids the visualization of head anatomy relevant to the procedure. In addition, the camera angle is kept consistent to keep the viewer oriented to head positioning. This animation is not intended to show diversity as the patient is represented as a generic person with no identifiable ethnicity. This animation aims to make content more accessible for viewers to hear as the background music was kept significantly lower than the audio speech. All text in this animation has a contrast ratio of at least 5.5: 1, most being 9.5: 1
