Abstract

Son yıllarda kullanımı gittikçe yaygınlaşan üç boyutlu görüntüleme ve modelleme yöntemleri, iki boyutlu çalışmaların yerini almaktadır. Tıp alanında da yaygın kullanımı olan üç boyutlu görüntüler özellikle nöroşirurji pratiğinde cerrahi açıdan kolaylıklar sağlamaktadır. Üç boyutlu görüntüler esas alınarak epilepsi, kranioplasti, vasküler ve intrakranial lezyonların cerrahisi şekilllendirilebilmektedir. Daha önceki ameliyata ya da travmaya bağlı olarak kemik doku kaybının yerine konup, beyin dokusunun korunması kranioplastinin asıl amacıdır. Bu amaçla otolog greftler kullanılabileceği gibi polimetilmetakrilat gibi maddeler de kullanılmaktadır. Bu çalışmada kranioplasti planlanan hasta için üç boyutlu yazıcı kullanılarak PLA kalıbı üretilmiştir ve PMMA ile kranioplasti işlemi gerçekleştirilmiştir. Hastanın perop gözleminde kalıbın tam olarak oturduğu görülmüştür. Hasta takiplerinde kozmetik açıdan memnundu. Teknolojinin ilerlemesi ile birlikte üç boyutlu yazıcıların nöroşirurji pratiğinde kullanımı daha da artacak, kişisel tedavi yöntemleri geliştirilecek, daha az maliyet ve komplikasyon oranları ile daha iyi sonuçlar elde edilecektir.

Polymethylmethacrylate cranioplasty implant customized using a polylactic acid mold and prepared with a 3D printer: an example case

Abstract

In recent years, the use of three-dimensional imaging and modeling methods has become increasingly frequent, replacing two-dimensional studies. Three-dimensional images, which are widely used in medicine, provide surgical facilities, especially in neurosurgical practice. Surgery for epilepsy, cranioplasty, vascular and intracranial lesions could be shaped based on three-dimensional images. The main purpose of cranioplasty is to replace bone tissue loss due to previous surgery or trauma to protect brain tissue. For this purpose, autologous grafts could be used as well as materials such as polymethylmethacrylate. In this study, a PLA mold was produced using a three-dimensional printer for the patient who was planned for cranioplasty and cranioplasty was performed with PMMA. The perioperative observation of the patient revealed that the mold was fully seated. The patient was satisfied cosmetically in the follow-up. With the advancement of technology, the use of three-dimensional printers in neurosurgery practice will further increase, individual treatment methods will be developed and better results will be obtained with less cost and complication rates.
