Then analysis and segmentation of images were done. All CT, CTA, MRI, and DTI image data were stored in the standard format according to Digital Imaging and Communication in Medicine (DICOM). In every case, patients' imaging data were acquired by various techniques including magnetic resonance imaging (MRI), computed tomography (CT), computed tomography angiography (CTA), and diffusion tensor imaging. Gross total excision, facial nerve preservationįacial nerve location did not correlate intraoperatively. Relation of facial nerve to tumor found accurately.

This is the first reported series of 3D-printed skull base tumors (five cases) in our country as per our knowledge. Researches on 3D-printed tumor models along with cranial nerves are not being frequently reported. The development of 3D models by rapid prototyping technique is being increasingly utilized in many surgical specialities.īenefit of this technology in improving surgical blueprint, aiding in diagnostic quality, decreasing blood loss, and shortening operating time have been favorably reported. Here patients imaging data can be compiled into a 3D-printed model allowing a more practical assessment along with simulation preoperatively. This technology allows surgeons to develop their operative precision. Surgeons have relied on cadaver specimens for better anatomical mileage and honing their surgical skillset, but cadavers are difficult to acquire. Traditionally surgeon's anatomical knowledge, surgical skills, and experience, aided with intraoperative neurophysiologic monitoring and neuronavigation were utilized for proper tumor resection and protecting surrounding structures. Micro-neurosurgical techniques have undergone rapid advancement with shifting of attention in skull base surgery to preserve important cranial blood vessels and nerves along with maximal tumor resection.
Skull base contains many major neurovascular structures in a confined space, along with anatomical variations making surgical approaches to this region challenging.ĭevelopment of surgical training devices to improve the required surgical skills along with the precise diagnosis and proper surgical plans are needed to reduce surgical complications. Tumors of the skull base are commonly benign compared with those in other anatomical locations and complete excision leads to good outcome. Application of three-dimensional (3D) printing technology in neurosurgery have gained popularity nowadays.
