Rehabilitation of head and neck defects following trauma, oncologic resection, or congenital malformation is a challenging task. Not only is the restoration of three-dimensional form necessary for acceptable cosmesis, but simultaneous restoration of functional speech and swallow is also essential for optimal reconstruction outcomes. While advances in free tissue transfer have allowed surgical reconstruction of head and neck defects once considered inoperable and associated with poor quality of life, not all patients are ideal surgical candidates. As such, nonsurgical solutions to both functional and cosmetic restoration remain a necessary alternative option. Facial prostheses and palatomaxillary obturators have evolved with increasingly biocompatible materials as well as retention systems to address significant defects that challenge the limits of surgical reconstruction.
创伤、肿瘤切除或先天性畸形后头颈部缺损的修复是一项具有挑战性的任务。不仅恢复三维形态对于可接受的美容效果是必要的，而且同时恢复功能性言语和吞咽对于最佳重建结果也至关重要。虽然游离组织移植的进展使得曾经被认为无法手术且与生活质量差相关的头颈部缺损能够进行手术重建，但并非所有患者都是理想的手术候选人。因此，功能和美容修复的非手术解决方案仍然是必要的替代选择。面部假体和腭上颌阻塞器随着生物相容性越来越高的材料以及固位系统的发展而不断演进，以解决挑战手术重建极限的重大缺损。
