Three-Dimensional Digital Technology: A Powerful Assistant for the Reconstruction of Complex Craniofacial Deformities.

Three-dimensional digital technology has been widely applied in craniofacial surgeries, particularly in conventional procedures such as facial contouring and orthognathic surgery. To some extent, the process has already been standardized. As to reconstruction surgeries of complex craniofacial deformity, however, surgical plans need to be patient-specific. Traditionally, individualized surgical treatment largely relies on the surgeon's clinical experience. The application of digital technology mainly focuses on preoperative planning and postoperative evaluation of surgical outcomes rather than intraoperative patient-specific implants or osteotomy guides. For patients with complex craniofacial deformities, requirements for accurate 3-dimensional digital technology can be much higher. This study presents a favorable surgical reconstruction of the severe craniofacial deformity using 3-dimensional digital technology, providing references for craniofacial surgeons, which could be beneficial to clinical practice and treatment efficacy.
