Reconstruction of the midface remains a challenging task for even the most experienced surgeon, with a host of reconstructive options including free tissue transfer, allografts, or prosthetic implants. Presented here is a case of idiopathic bony destruction of the right midface in a 19year old female, creating a unique defect requiring repair.
Demonstrate a unique case of severe maxillary degeneration and discuss the associated reconstructive challenges and final repair with a prosthetic implant.
Case report.
The patient presented with a 7month history of an idiopathic progressive deformity of the right cheek. Computed tomography of the paranasal sinuses revealed extensive bone loss of the right midface and orbit. The patient underwent facial reconstruction using a customized Medpor (Stryker Corp, Kalamazoo, MI) implant. At 6month follow-up the patient and physician were both pleased with the patient's overall appearance. The patient did have some residual lower lid retraction present as well as some lateral pull at the lateral canthus outward from the orbit itself.
Preoperative planning for midface reconstruction requires a deep understanding of the aesthetic, functional, and supportive roles this structure holds. Computer assistance allows the creation of custom made implants, providing the reconstructive surgeon with innovative options for reconstruction with minimal morbidity to the patient. As the technology around the design and creation of the custom implants continues to improve, the role of computer assistance in reconstruction will become more prominent.
即使对于经验最丰富的外科医生而言,面中部重建仍然是一项具有挑战性的任务,存在多种重建选择,包括游离组织移植、同种异体移植或假体植入。本文介绍了一名19岁女性右面部特发性骨破坏的病例,该病例造成了独特的缺损需要修复。
展示一例严重上颌骨退变的独特病例,并讨论相关的重建挑战以及使用假体植入的最终修复情况。
病例报告。
该患者有右脸颊特发性进行性畸形7个月的病史。鼻窦计算机断层扫描显示右面部和眼眶广泛骨质流失。患者使用定制的Medpor(史赛克公司,密歇根州卡拉马祖)植入物进行了面部重建。在6个月的随访中,患者和医生对患者的整体外观均感到满意。患者确实存在一些下睑退缩残留,以及外眦从眼眶本身向外有一些侧向牵拉。
面中部重建的术前规划需要深入了解该结构所起的美学、功能和支撑作用。计算机辅助能够制作定制植入物,为重建外科医生提供创新的重建选择,同时使患者的发病率降至最低。随着定制植入物设计和制作技术的不断改进,计算机辅助在重建中的作用将变得更加突出。
