Recently, endoscopic pituitary surgery is increasingly being used in pituitary surgery. Compared to conventional microscopic pituitary surgery, outcomes have been non-inferior, so endoscopic pituitary surgery has become an established surgical technique. However, this is a highly specialized surgery and sophisticated surgical techniques are required. We report our development of a training model for endoscopic endonasal transsphenoidal surgery.
Our training model is constructed using a skull model and eggs. The sella turcica of the skull model is hollowed out and an egg is placed. The bottom of the egg simulates the sella turcica floor and the egg contents simulate a tumor. Training is conducted using this model in an actual operating room with actual surgical instruments.
This model is highly realistic and is within acceptable limits as a surgical simulation. Since practice can be repeated, this model is effective for familiarization with endoscopic imaging and to increase technical skills such as drilling and curetting. In addition, variations in eggs, ranging from raw eggs to boiled eggs, can be used to simulate various tumors for training.
This training model using a skull model and eggs is useful to improve surgical techniques in endoscopic endonasal transsphenoidal surgery.
最近，内镜经鼻蝶窦垂体手术在垂体手术中越来越多地被应用。与传统的显微镜下垂体手术相比，其结果并不逊色，因此内镜经鼻蝶窦垂体手术已成为一种成熟的手术技术。然而，这是一项高度专业化的手术，需要精湛的手术技术。我们报告了我们开发的内镜经鼻蝶窦垂体手术训练模型。
我们的训练模型是使用颅骨模型和鸡蛋构建的。颅骨模型的蝶鞍被掏空，放入一个鸡蛋。鸡蛋的底部模拟蝶鞍底部，鸡蛋内容物模拟肿瘤。使用实际手术器械在实际手术室中使用该模型进行训练。
该模型非常逼真，可作为手术模拟的有效手段。由于可以重复练习，因此该模型有助于熟悉内镜成像，并提高钻孔和刮除等技术技能。此外，还可以使用各种鸡蛋，从生鸡蛋到煮鸡蛋，来模拟各种肿瘤进行训练。
使用颅骨模型和鸡蛋的这种训练模型有助于提高内镜经鼻蝶窦垂体手术的手术技术。
