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.

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

Öz

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.
