摘要
头颈部肿瘤切除引起的软组织缺损会严重影响患者的外貌和心理健康。人体头颈部曲面十分复杂,如何精确修复使术后患者面部实现理想的美学与功能效果,是颌面外科医生一直试图解决的难题。本文以志愿者正常头颈部为对象,基于曲面高斯曲率分析,结合软组织临床处理的力学约束和主曲率分析方法,得到精准的头颈部曲面可展/不可展区域分区图,构建不可展曲面的展平方法。在此基础上,提出头颈部软组织缺损修复皮瓣的数字化设计方法,进行体外模拟手术实验研究。最后选取一例扁桃体肿瘤患者进行临床验证。结果表明,利用数字化技术设计的皮瓣能够提高头颈部软组织缺损修复手术的精度和术后美学效果。本文验证了头颈部肿瘤切除后软组织缺损的数字化精确修复技术的可行性,可有效地辅助外科医生完成皮瓣移植精确重建手术,从而提高患者术后满意度。
Soft tissue defects resulting from head and neck tumor resection seriously impact the physical appearance and psychological well-being of patients.The complex curvature of the human head and neck poses a formidable challenge for maxillofacial surgeons to achieve precise aesthetic and functional restoration after surgery.To this end,a normal head and neck volunteer was selected as the subject of investigation.Employing Gaussian curvature analysis,combined with mechanical constraints and principal curvature analysis methods of soft tissue clinical treatment,a precise developable/non-developable area partition map of the head and neck surface was obtained,and a nondevelopable surface was constructed.Subsequently,a digital design method was proposed for the repair of head and neck soft tissue defects,and an in vitro simulated surgery experiment was conducted.Clinical verification was performed on a patient with tonsil tumor,and the results demonstrated that digital technology-designed flaps improved the accuracy and aesthetic outcome of head and neck soft tissue defect repair surgery.This study validates the feasibility of digital precision repair technology for soft tissue defects after head and neck tumor resection,which effectively assists surgeons in achieving precise flap transplantation reconstruction and improves patients’postoperative satisfaction.
