The purpose of our study is to develop a high-fidelity thyroid education model, that can be utilized for patient education. This model can assist them in gaining a better understanding of the thyroid's structure, providing patients with insights into their own conditions and thyroid fine needle aspiration examinations.

Background： Thyroid nodular disorder is one of the most common diseases in Endocrine clinics. And thyroid fine needle aspiration examination is the most important exam in evaluating the nature of thyroid nodules. In previous studies, 3D thyroid models have been introduced for patient education before thyroid surgery. Nevertheless, thyroid models that can be used to practice thyroid fine needle aspiration examination were scarce.

Study Design： This is a prospective study.

Methods： In our study, 3D printing technology will be used to create the thyroid high-fidelity model. We plan to choose 3D printing materials that explain thyroid fine needle aspiration for patient education efficacy evaluation.

Effect： Through the creation of this thyroid fine needle aspiration model, we hope to enhance patients' comprehension of the thyroid and thyroid nodules. The results of our study could be applied in hospitals to improve patient education.
