RESUMEN
Objective To study the clinic value of digital three-dimensional shaping titanium mesh in repairing skull defects and reconstructing temporal muscle attachment points. Methods Eighty-two patients with skull defects from December 2013 to January 2016 were enrolled in this study. They were divided into two groups according to patients' will with 41 patients in each group. The patients in control group received traditional hand-shaping titanium mesh repair, the patients in observation group received individual digital forming technology to produce titanium mesh repair and reconstruct the temporal muscle attachment points at the titanium mesh temporal corresponding position. The rate of appearance satisfaction, operation time, the number of titanium nail and the rate of postsurgery adverse reaction was compared between the two groups. Results The rate of appearance satisfaction in observation group was significantly higher than that in control group: 97.56%(40/41) vs. 80.49%(33/41), P<0.05. The operation time and the number of titanium nail and in observation group was significantly lower than that in control group:(8.9 ± 1.6) h vs. (12.4 ± 2.4) h, (10.3 ± 0.9) pieces vs. (11.8 ± 1.8) pieces, P < 0.01. The rate of postsurgery adverse reaction in observation group was significantly lower than that in control group: 0 vs. 9.8%(4/41), χ2 = 4.21, P < 0.05. Conclusions The operation of repairing skull defects and reconstructing temporal muscle attachment points with digital three-dimensional shaping titanium mesh is simple. It can shorten the operation time, decrease the postsurgery adverse reaction, and increase the appearance satisfaction.
RESUMEN
Objective To investigate the clinical value of digital three-dimensional shaping titanium mesh and traditional hand-shaping titanium mesh in the repairing of skull defect surgery.Methods The clinical data of 78 patients with skull defect were retrospectively analyzed,they were divided into digital three-dimensional shaping titanium mesh group (41 cases) and traditional hand-shaping titanium mesh group (37 cases) according to the different titanium net,then the hospital stay,operative time,hospital costs,shaping satisfaction and postoperative complications between two groups were compared.Results The hospital costs and shaping satisfaction in digital three-dimensional shaping titanium mesh group were significantly higher than those in traditional hand-shaping titanium mesh group [(12 978.1 ± 4 765.7) yuan vs.(9 436.6 ±3 798.7) yuan,(9.87 ±0.13) scores vs.(9.41 ±0.09) scores],the complication rate was significantly lower than that in traditional hand-shaping titanium mesh group [4.9％ (2/41) vs.29.7％ (11/37)],there was significant difference (P ＜ 0.05).The hospital stay and operative time between two groups had no significant difference (P ＞ 0.05).Conclusion The digital three-dimensional shaping titanium mesh repair is convenient to operate,it can largely reduce the risks and complications of surgery,and can also achieve a high standard of modeling results,so is worthy of promotion.
