5. Sınıf Öğrencilerine Anlatılan Toraks Anatomisi Dersi Kapsamında 3D Printer ile Basımı Yapılmış Mediasten Modelinin Lenf Nodu İstasyonlarını ve Zonlarını Öğrenmedeki Etkisi

Çalışmamızda mediasten lenf nodlarının BT incelemelerde doğru anlaşılması ve akılda tutulması özellikle tıp öğrencileri için zor bir süreç olup bu süreci kolaylaştırmak adına 3D yazıcı ile basımı yapılmış mediasten modelini beşinci sınıf öğrencilerinin eğitiminde kullanarak öğrenmedeki etkisini ölçmeyi hedefledik. Bu çalışma ESOGÜ Tıp Fakültesi’nde 15.02.2018-15.05.2019 tarihleri arasında prospektif olarak beşinci sınıf öğrencilerinin Radyoloji stajı içerisinde anlatılan Toraks Anatomisi dersi kapsamında iki döngü halinde yapıldı. beşinci sınıf öğrencilerine önce teorik ders anlatılıp, IASLC (International Association for the Study of Lung Cancer) lenf nodu haritasına göre 1-14 aralığındaki lenf nodu istasyonları ve zonları kesitsel iki boyutlu görsellerle desteklenerek anlatıldı. Daha sonra dersin pratik saatinin sonunda yazılı onamı alınmış öğrenciler iki gruba ayrıldı, bir gruba lenf nodu istasyonları ve zonları power point ders materyalleriyle anlatıldı. Diğer gruba Ultimaker 3 Extended üç boyutlu (3D) yazıcı ile katman birikimli modelleme yöntemi ile yapılan mediasten modelinden faydalanılarak anlatım yapıldı. Sonuçlar SPSS’de bağımlı örneklem t testi ile analiz edilip sonuçlar tablo haline getirildi. Bağımlı örneklem t testine göre 3D yazıcı ile basımı yapılan mediasten modeli ile anlatılan öğrenci grubu, power point ile anlatılan öğrenci grubuna göre daha fazla soru sayısı ortalamasına sahip olup anlamlı farklılık saptandı (t: 3.07, p:0.05).3D yazıcı tıp eğitiminde anatomik yapıları göstermede, pratik yaptırmada önemli bir yere gelmiştir. Mediastinal lenf nodları gibi zor, kafa karıştıran anatomik lokalizasyonlarda 3D yazıcı ile ders anlatımını desteklemek öğrenciler için olumlu sonuçlar verecektir.

Effect of Mediastinum Model Printed with 3D Printer on Learning Lymph Node Stations and Zones Within the Scope of Thoracic Anatomy Course Explained to 5th Grade Students

The aim of this study was to determine the effect of mediastinum lymph nodes on CT examinations and to measure the effect of using 3D printer-mediated mediastinum model in the education of fifth grade students in order to facilitate this process. This study was carried out in two cycles in the scope of Thorax Anatomy, which was described prospectively between the dates of 15.02.2018-15.05.2019 in the 5th grade students of ESOGU Faculty of Medicine. Fifth grade students were informed firstly and the lymph node stations in 1-14 range and their zones were supported by cross-sectional two-dimensional images according to IASLC (International Association for the Study of Lung Cancer) lymph node map. Then, at the end of the practical time of the course, students with written informed consent were divided into two groups; one group was told with lymph node stations and zones with power point course materials. The other group was described by using the Ultimaker 3 Extended three-dimensional (3D) printer and the mediastinum model with layer cumulative modeling method. The results were analyzed with dependent sample t test in SPSS and the results were tabulated. According to the dependent sample t test, the group of students described with the mediastin model printed by 3D printer had a higher mean number of questions than the student group described by power point and a significant difference was found (t: 3.07, p: 0.05). The 3D printer has an important place in demonstrating the anatomical structures and practicing in medical education. In difficult, confusing anatomical localizations such as mediastinal lymph nodes, it will give positive results for the students to support the lecture with the 3D printer.
