Abstract
Three-dimensional (3D) printing technology in neurosurgery has gained popularity nowadays. Skull base contains many major neurovascular structures in a confined space, along with anatomical variations making surgical approaches to this region challenging. 3D-printed model of skull base tumors consists of the patient's bony skull base, actual tumor dimensions, and surrounding major neurovascular structures. We included a total number of five patients with skull base tumors (one case of planum sphenoidale meningioma, two cases of sellar tumor with suprasellar extension, and two cases of cerebellopontine angle tumor) and 3D-printed tumor model of each of them. These models were used for preoperative simulation and served as very true to life training tool. These help in increasing the efficacy of the surgeon, improves surgical safety and ergonomics. They were also used for patient counselling, educating about the disease, the surgical procedure, and associated risks.
