There are patients with craniofacial deformity that can lead to extensive bone loss and severe disfigurement. Autologous reconstruction may be challenging in these patients, and it is usually associated with flap donor area morbidity and unfavorable aesthetic and functional results. A 51-year-old patient with human immunodeficiency virus infection, developed in the context of immunosuppression a fulminant fungal rhino-sinusitis with the need for surgical debridement, and in consequence extensive destruction of the nasal cavity and upper jaw, resulting in severe disfigurement due to nasal deformity and maxillary collapse. Human immunodeficiency virus disease was controlled and the complex craniofacial defect was posteriorly reconstructed with direct 3-dimensional (3D) printing combined with microsurgical free tissue transfer. The 3D facial implant, in titanium, was individualized and fabricated based on computed tomography images of the patient. A radial forearm free flap was used since a soft-tissue defect was anticipated after scar release and implant placement. It allowed simultaneous coverage of the palate, the anterior surface of maxilla and intranasal lining. The flap survived despite flap venous congestion in the postoperative period probably facilitated because of the complex 3D flap configuration and pedicle tunneling into the neck. After 9 months, the patient showed a tremendous aesthetic and functional improvement. The 3D printing was useful in our patient with craniofacial reconstruction. Its combination with free tissue transfer may improve the surgeon's armamentarium when dealing with complex patients.
有些患有颅面畸形的患者会出现大面积骨质流失和严重毁容。对这些患者进行自体重建可能具有挑战性,而且通常会伴有皮瓣供区并发症以及不理想的美学和功能效果。一名51岁的人类免疫缺陷病毒感染患者,在免疫抑制的情况下患上暴发性真菌性鼻-鼻窦炎,需要进行手术清创,结果鼻腔和上颌骨遭到广泛破坏,因鼻畸形和上颌骨塌陷而导致严重毁容。人类免疫缺陷病毒疾病得到控制后,采用直接三维(3D)打印结合显微外科游离组织移植对复杂的颅面缺损进行了后部重建。3D面部钛植入物是根据患者的计算机断层扫描图像定制制作的。由于预计在瘢痕松解和植入物置入后会出现软组织缺损,因此使用了桡侧前臂游离皮瓣。它能够同时覆盖腭部、上颌骨前表面和鼻内衬里。尽管术后皮瓣出现静脉淤血,但由于复杂的3D皮瓣构型和蒂部隧道通向颈部,皮瓣得以存活。9个月后,患者的美学和功能有了极大改善。3D打印对我们这位进行颅面重建的患者很有用。它与游离组织移植相结合,在处理复杂患者时可能会改善外科医生的技术手段。
