Osseointegrated craniofacial implants have improved retention and patients' perceptions of implant-retained nasal prostheses; however, the determination of the available bone sites for implant placement post-rhinectomy is difficult. This case report describes the use of cone beam computed tomography scanning and computer-assisted virtual planning in conjunction with digital photographs for rehabilitation of a facial defect with an implant-retained silicon nasal prosthesis. Two implants were planned in the anatomical area with adequate bone volume to achieve favorable cosmetic outcomes and accessibility for hygiene maintenance. The implant-retained nasal prosthesis resulted in a meaningful improvement in the esthetics without the need for plastic surgery. In such cases, the post-rhinectomy reconstruction surgery should be limited to preparation of the surgical defect area for an implant-retained prosthesis. Silicone prostheses are reliable alternatives to surgery and should be considered in selected cases.
骨结合式颅面植入物改善了植入物固位以及患者对植入物固位鼻假体的感受;然而,确定鼻切除术后可用于植入物放置的骨位点很困难。本病例报告描述了使用锥形束计算机断层扫描和计算机辅助虚拟规划并结合数码照片,用植入物固位的硅鼻假体修复面部缺损。在有足够骨量的解剖区域计划植入两枚植入物,以实现良好的美容效果并便于进行卫生维护。植入物固位鼻假体在无需整形手术的情况下显著改善了美观。在这类病例中,鼻切除术后重建手术应限于为植入物固位假体准备手术缺损区域。硅胶假体是手术的可靠替代方案,在特定病例中应予以考虑。
