颌骨肿瘤计算机辅助下个性化诊疗的探讨

目的：计算机辅助下个性化诊疗颌骨肿瘤，提高诊断的准确性、手术的精确性，缩短了手术时间。方法：颌骨肿瘤病例40例，分为两组，每组20例。A组在计算机辅助下个性化诊疗，B组经三维重建得到的立体模型，按以往经验，术中切除肿瘤，常规取骨或重建板重建下颌骨。对比两组病例术前、术后三维CT重建效果，从冠状面、矢状面、横断面对比各个标记点较术前移位情况，手术时间，肿瘤复发率。结果：所有患者均顺利完成手术，术后三维CT重建显示A组重建的颌骨外形良好，与术前设计基本一致，颌骨标记点较术前平均移位（1．53±0．17）mm，随访2年均无复发。B组大部分颌骨外形良好，颌骨标记点较术前平均移位（3．53±0．57）mm，随访2年有2例复发。结论：计算机辅助下个性化诊疗颌骨肿瘤，可提高诊断的准确性及修复效果，缩短了手术时间。

A study of computer-assisted personalized treatment of maxillofacial bone tumor

Objective:The applications o of the computer-assisted personalized therapy of maxillofacial bone tumor, may improve the accuracy of diagnosis and surgical precision and reduce surgery time. Method:40 patients with maxillofa-cial bone tumor were collected,and were randomly divided into A,B two group. Patients in group A were treated with com-puter-assisted personalized therapy,the three-dimensional model was obtained after reconstruction of group B patients,ac-cording to past experience,remove the tumor and reconstructed mandible. Then 3D CT reconstructions were performed in every patient The assessments of maxillofacial markers were gained from coronal,sagittal,cross-sectional and the surgery time and the tumor recurrence rate. Result:All patients were successfully operated,three-dimensional CT reconstruction dis-playing all patients in group A reconstruction of the mandible in wonderful shape,consistent with the preoperative design, maxillofacial markers compared with preoperative average shift (1.53±0.17) mm,all patients have been follow-up 2 years, there is no relapse. Group B patients in good shape most of the mandible,maxillofacial markers compared with preoperative mean shift(3.53±0.57) mm,all patients have been follow-up 2 years,2 cases recurring. Conclusion:computer-assisted per-sonalized therapy of maxillofacial bone tumor can effectively improves the accuracy of diagnosis,improved repair effect,re-duce the operation time.
