Reconstructing maxillofacial defects is quite challenging for most surgeons due to the region's complex anatomy and cosmetic and functional effects on patients. The use of pre-made alloplastic implants and autogenous grafts is often associated with resorption, infection, and displacement. Recent technological advances have led to the use of custom computer-designed patient-specific implants (PSIs) in reconstructive surgery. This study describes our experience with PSI, details the complications we faced, how to overcome them, and finally, evaluates patient satisfaction.
Six patients underwent reconstruction of various maxillofacial defects arising due to different etiologies using PSI. A combined total of 10 implants was used. PEEK was used to fabricate 8, while titanium was used to fabricate 2. No complications were seen in any patient both immediately post-op and in subsequent follow-ups. All patients reported a high level of satisfaction with the final result both functionally and cosmetically.
The use of computer-designed PSI enables a more accurate reconstruction of maxillofacial defects, eliminating the usual complications seen in preformed implants and resulting in higher patient satisfaction. Its main drawback is its high cost.
由于颌面部区域解剖结构复杂,且对患者的美观和功能有影响,因此对大多数外科医生来说,重建颌面部缺损极具挑战性。使用预制的异体植入物和自体移植物常常会出现吸收、感染和移位等问题。最近的技术进步使得定制的计算机设计的患者特异性植入物(PSI)在重建手术中得到应用。本研究描述了我们使用PSI的经验,详细介绍了我们所面临的并发症、如何克服这些并发症,最后评估了患者的满意度。
6例患者因不同病因导致的各种颌面部缺损,使用PSI进行了重建。总共使用了10枚植入物。其中8枚采用聚醚醚酮(PEEK)制作,2枚采用钛制作。术后即刻及随后的随访中,所有患者均未出现并发症。所有患者对最终结果在功能和美观方面均表示高度满意。
使用计算机设计的PSI能够更准确地重建颌面部缺损,消除了预制植入物中常见的并发症,提高了患者满意度。其主要缺点是成本高昂。
