Unveiling the Intricacies of the Inner Ear Anatomy: Novel 3D-Printed Model for Detailed Visualization and Functional Demonstrations.

Objectives: This research aimed to print realistically detailed and magnified three-dimensional models of the inner ear, specifically focusing on visualising its complex labyrinth structure and functioning simulation.

Methods: Temporal bone computed-tomography data were imported into Mimics software to construct an initial three-dimensional inner-ear model. Subsequently, the model was amplified and printed with precision using a three-dimensional printer.

Association of changes in lipids with risk of myocardial infarction among people without lipid-lowering therapy.

Background And Aims: Although serum lipids are widely accepted as independent predictors of myocardial infarction (MI), there is insufficient evidence for associations of changes in lipid levels with MI. The present study aimed at investigating the associations between changes in lipids and incidence of MI in people without lipid-lowering therapy.

Methods: 64,031 Chinese participants (mean age: 53.

Associations between changes in serum uric acid and the risk of myocardial infarction.

Background: The role of serum uric acid (SUA) in development of myocardial infarction (MI) is controversial. The current study aimed to investigate the association between both baseline SUA and changes in SUA and the risk of MI.

Methods: The current study included 71,449 Chinese participants (mean age, 50.

A novel three-dimensional-printed paranasal sinus-skull base anatomical model.

Purpose: A novel precision three-dimensional (3D)-printed paranasal sinus-skull base anatomical model was generated with a commercial grade desktop 3D printer. A specific page-turning pattern was employed in this model, to display the internal spatial structure of the paranasal sinus.

Methods: The CT image data of paranasal sinus were imported into the Mimics software to construct a 3D digital paranasal sinus-skull base model.
