Watertight Dural Closure in Brain Surgery: A Simple Model for Training

Abstract

The described model represents a new, simple, effective and affordable device to be used for neurosurgical training in the procedures of duraplasty and to test the efficacy of watertight closures.

Theoretical substantiation of the efficiency of biopolymers application in experimental TBI (literature review and own results)

“…Частота виникнення ліквореї після краніотомії становить 7-10 % [3][4][5]. Вважають, що герметичне закрит тя ТМО асоціюється зі зниженням частоти ліквореї і меншою кількістю локальних інфекційних ускладнень [6,7]. У зв'язку з цим застосування біодеградувальних матеріалів, які сприяють репарації дефектів ТМО, є актуальним і має не лише медичне, а і соціальне значення.…”

40 Training in Skull Base Surgery

“…[30][31][32][33][34][35][36] Such models contain colored blood vessels and dural sinuses, cranial nerves, brain, silicon structures that can also be used for bypasses, bone-like structures that can be drilled, and synthetic dura mater that can be sutured. CT/magnetic resonance imaging (MRI)-based 3D models produced using laser-sintered powdered polymers and 3D printers are also used for anatomy training and surgery simulation, [37][38][39][40][41][42] allowing for biomodeling of skull base and associated tumors and other lesions.…”

Composite chitosan/polyethylene oxide film for duraplasty in traumatic brain injury model in rats

“…Hermetic closure of the dura mater correlates with a decrease in the intensity of liquorrhea and a decrease in the rate of infectious complications [2,3]. This issue is especially urgent after the decompression trepanation due to severe traumatic brain injury or acute cerebrovascular accident [4,5]; surgery on the skull and posterior fossa, when DM defect is created as a result of bipolar coagulation; the dural resection following meningioma surgery [6], as well as spinal neurosurgery [7].…”
