Abstract:
Objective:To explore the application value of individualized three-dimensional (3D) printing positioning guides in localization and resection of intracranial lesions.Methods:Fifteen patients with intracranial space occupying lesions underwent resection in our hospital from March 2021 to May 2021 were selected in our study. Brain images by CT and MRI as raw data were used to design individual positioning guides. The positioning guides were placed on the patient's skin before resection to mark the location and boundary of the lesions with a marker, and neuro-navigation was used to verify the accuracy. During the resection, the location of the lesions was identified through microscope by the surgeons. Postoperative CT and MRI were used to evaluate the lesion resection.Results:The individualized positioning guides of 15 patients fit the skin well, and the skin incision and bone window were designed to meet the surgical requirements. All surgeries were completed in one time, and the lesion tissues were successfully removed. During the surgeries, the skin incision was not adjusted for secondary expansion. Brain MRI reexamination within 48 h of surgery showed that the lesions of 11 patients with tumors were removed satisfactorily (total resection in 9 and subtotal resection in 2); brain CT reexamination within 12 h showed that the clearance rate of hematomas in 3 patients was above 80% and that in 1 patient was 70%. No patients had cerebrospinal fluid leakage, intracranial hematoma, intracranial infection or other serious complications. All patients recovered well during the 1-3 months of outpatient/telephone follow-up.Conclusion:The positioning method with personalized 3D printing guides is simple and convenient, enjoying accurate positioning results, which can assist the clinicians to optimize the preoperative planning, optimize the surgical incision design, and is worthy of promotion and application in primary hospitals.
