Application of three-dimensional printing technology in the surgical treatment of nasal skull base tumor / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

Objective@#To explore the application value of three dimensional (3D) printing technique in the surgical treatment of nasal skull base tumor.@*Methods@#Seven patients with complicated skull base tumors admitted in Department of Otorhinolaryngology Head and Neck Surgery and Department of Neurosurgery of Tianjin HuanHu Hospital from Mar. 2017 to Feb. 2018 were selected. According to three sets of DICOM data of patients obtained from enhanced spiral CT scanning, navigation MRI scanning and CT angiography (CTA) magnetic navigation, data information of skull, blood vessel and tumor were extracted and reconstructed with different segmentation methods. The assembly and integration were achieved in the same coordinate system to form 3D visual composite virtual models. Combined with 3D printing technology, 3D visual composite virtual models were substantialized, and were applied for preoperative surgical strategy making and intraoperative reference.@*Results@#Virtual models of the nasal skull base of 7 patients were reconstructed successfully and 3D 1∶1 entity models were produced. The models demonstrated the relationship among the skull, tumors, and adjacent blood vessels.Seven cases were successfully performed.@*Conclusion@#3D virtual model of composite nasal skull base and its dissection model based on 3D printing technology can guide the medical staff to develop and perfect the operation scheme.
