Facial Reconstruction Based on Combined Three-Dimensional Printing and Microsurgical Free Transfer

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 cran...
