术前(左),术后(右)。5月30日,澎湃新闻记者从上海儿童医学中心获悉,小宇的手术获得成功,脑袋恢复情况很好,外表呈圆润饱满状,五官也较术前端正可爱。
手术影像检查。在此次治疗过程中,医学专家由于在术前运用了3D打印技术,等比还原患儿颅骨,使得术中手术更具精确性、减少出血风险等,并且使重塑后的面容更具家族特征。
医生介绍,手术有两个重要的目的:一是要把患者畸形的颅骨全部拆卸,松解被压迫的大脑;二是对颅骨进行分割,逐个塑成需要的形状,再重新拼接,这个过程就像玩拼图一样。然而,手术不仅需要技术,还要有立体裁剪的艺术美感,对于这个不到1周岁的孩子来说风险很大,也可能存在出血的可能。因此,手术前考虑采用3D建模的形式等比例还原患儿头骨,在模型上预先设定裁剪方案、手术切割线等,确保“精准手术”。
3D建模成功后,医生鲍南一边在脑中想像着裁剪方案,一边在这个立体的、真实的头骨模型上画下了手术切割线。“实物模型不仅为手术方案提供精准指南,还可以通过提前测量父母面部数据,为患儿塑形后的面容体现父母特征提供依据。”他说。
手术过程。鲍南医生介绍,目前,对于狭颅症的治疗方法首选手术,最好的手术时机为6个月-1岁时手术,可尽量减少对大脑发育的影响。
