Trigeminal neuralgia is a common cause of facial pain, characterized by shock-like pain affecting one or more branches of the trigeminal nerve. When conservative treatment fails and microdecompression is not indicated, percutaneous procedures are helpful. This percutaneous approach is done by a puncture up to the Gasserian ganglion, through the foramen ovale. Although simple and safe, this puncture demands some expertise from neurosurgeons. For that, a partnership between neurosurgeons and bio-engineers has developed a model for foramen ovale puncture, allowing practice for residents and young neurosurgeons.
A model for foramen ovale puncture has been created by interposition of synthetic materials over a skull, simulating the human face.
This model has shown great similarity with that found in conventional surgeries, even upon repeated testing by experienced functional neurosurgeons and young residents.
This model for foramen ovale puncture training has demonstrated valuable help for initial practicing of this common neurosurgical procedure, particularly in centers where there are not many cadavers available for training.
三叉神经痛是面部疼痛的常见病因，其特征为影响三叉神经一个或多个分支的电击样疼痛。当保守治疗失败且不适合进行显微减压时，经皮手术会有所帮助。这种经皮方法是通过卵圆孔穿刺至半月神经节。尽管这种穿刺简单且安全，但需要神经外科医生具备一定的专业技能。为此，神经外科医生与生物工程师合作开发了一种卵圆孔穿刺模型，供住院医师和年轻神经外科医生练习。
通过在颅骨上放置合成材料模拟人脸，创建了一种卵圆孔穿刺模型。
即使经过经验丰富的功能神经外科医生和年轻住院医师的反复测试，该模型与传统手术中的情况仍显示出高度相似性。
这种卵圆孔穿刺训练模型已证明对这一常见神经外科手术的初步练习有宝贵帮助，特别是在没有很多尸体可供训练的中心。
