Abstract: One aspect of the present disclosure relates to a device for simulating a thyroid surgical procedure. The device can include a removable neck model configured to be accepted into a body model. The removable neck model can include a thyroid model that includes a first lobe and a second lobe connected by an isthmus, at least four parathyroid gland models arranged posterior to the thyroid model and spread between the lobes, and a nerve model. The nerve model can include a first superior laryngeal nerve model arranged medial and posterior to the first lobe, a second superior laryngeal nerve model arranged medial and posterior to the second lobe, a first recurrent laryngeal nerve model arranged medial and posterior to the first lobe, and a second recurrent laryngeal nerve model arranged medial and posterior to the second lobe.
