Application Of Improved 3D Digital Guide Plate Assisted Puncture In Microballoon Compression For Primary Trigeminal Neuralgia

ObjectiveTo investigate the clinical efficacy and application value of an improved 3D-printed guide plate for the treatment of primary trigeminal neuralgia(PTN)by percutaneous microballoon compression(PMC).MethodsThis prospective study included 42 patients with primary trigeminal neuralgia treated at the Depatment of Stomatology,Xuzhou Central Hospital from September 2019 to January 2022.The Group was randomly divided by random number table method into the research group(adopting 3D printing technology to make guide plate to guide punture,22 cases)and the control group(adopting the traditional Hartel anterior approach to position puncture,20 cases).The intraoperative success rate of the first puncture,puncture time,operative time,radiation exposure of patients and postoperative complications were compared between the two groups.Postoperative Barrow Neurological Institute Scale(BNI)scores,facial numbness,diminished corneal reflexes and chewing weakness were recorded.The t-test,rank sum test and chi-square test were used for statistical analysis,with P<0.05 indicating a statistical significant difference.ResultsThe research group was significantly better than the control group in terms of the success rate of the first puncture(χ2=21.51,P<0.001),puncture time(Z=-5.51,P<0.001),operative time(t=9.37,P<0.001),and number of C-arms scans(Z=-4.59,P<0.001).Postoperative BNI scores of the research group included 21 cases of grade I(95.5%)and 1 case of grade Ⅱ(4.5%),while the control group included 17 cases of grade Ⅰ(85.0%),2 cases of grade Ⅱ(10.0%)and 1 case of grade Ⅲ(5.0%),with no statistical significance(P>0.05).In the research group,16 patients had postoperative masseter weakness,1 had keratitis and 10 had perilabial heres,while in the control group,18 patients had postoperative masseter weakness,2 had keratitis,11 had perilabial heres and 1 had monocular blindness.There was no significant difference in postoperative complications between the two groups(P>0.05).At 12 months of follow-up,there was no recurrence in either the research or control group.ConclusionsImproved 3D digital guide plate guided percutaneous microballoon compression for primary trigeminal neuralgia can improve the accuracy and safety of puncture to a certain extent,obviously shorten the operation time,reduce radiation exposure of the patients,improve the success rate of the operation,and is easy to promote,which has a high clinical application value.
