Application of three dimensional (3D) curved multi‐planar reconstruction images in 3D printing mold assisted eyebrow arch keyhole microsurgery

Abstract

Abstract Objective The application of multi‐planar reconstruction of three dimensional (3D) curved surface in microsurgery of 3D printing mold assisted eyebrow arch keyhole approach was studied. Methods Eighty patients with intracranial aneurysms who underwent treatment at our hospital were enrolled. The patients were divided into two groups: the traditional eyebrow keyhole approach microsurgery group (38 cases in the conventional treatment group) and the three‐dimensional curved surface multi‐plane reconstruction image combined with 3D printing technology assisted eyebrow keyhole approach microsurgery group (42 cases in the 3D printing assisted treatment group). The Hunt‐Hess classification was used to make a preliminary estimation of the patient's condition. The 3D curved multi‐planar reconstruction method was used to assist the surgical plan; CT scan was used to establish a 3D printing mold, and the patient's condition and surgical plan were accurately analyzed before surgery. The operative time and the size of the incision area were recorded; postoperative GOS score and postoperative complications were statistically investigated. Results The 3D printing assisted treatment group (70.13 ± 15.56), (411.26 ± 10.38) mm2, the operative time and incision area were significantly shorter than the conventional treatment group (120.35 ± 20.46), (663.55 ± 13.54) mm2, p < .05); the GOS score showed that the 3D printing‐assisted treatment group was significantly higher than the conventional treatment group (p < .05). The postoperative complication rate was significantly lower in the 3D print‐assisted treatment group (9.52%) than in the conventional treatment group (47.36%, p < .05); the cure of intracranial aneurysms in the 3D printing assisted treatment group was more thorough than that in the conventional treatment group, and the difference was significant (p < .05). Conclusion Compared with the conventional eyebrow arch‐hole approach microsurgery, the 3D surface multi‐planar reconstruction image combined 3D printing assisted technology was safer and more effective, and the postoperative recovery was better and the incidence of complications was lower.
