Exploring 3D Printed Implants With Anti-Dropout Function to Overcome Time Constraints in Acute Orbital Fractures for Patient-Specific Implants.
Orbital wall reconstruction and implant insertion are crucial procedures for temporarily replacing the orbital walls in cases of significant fractures. Traditional methods using planar orbital implants have faced challenges owing to their flat shape, which increases the risk of dislocation from improper cuts and necessitates the use of screws in the orbital rim. This study aims to improve outcomes by employing customized 3-dimensional implants, thereby reducing complications and risk of dislocation resulting from external shock or implant weight postinsertion. This prospective study included 12 Korean individuals diagnosed with facial fractures (orbital wall injuries). Surgeries were performed on 12 patients, and follow-up CT scans were conducted on 10 of them. Therefore, the authors could only address the results for the 10 patients. The authors used bioactive glass ceramics and medical-grade poly-e-caprolactone to 3D print personalized implants, completing the manufacturing process in an average of 4.6 days. Computed tomography scans guided measurements of orbital volumes and exophthalmos. After surgery, we found that the difference values for bone orbital volumes (<0.1 mL) and exophthalmos (<1 mm except one) decreased compared with presurgery values. Independent t tests and Pearson correlation analysis revealed no significant changes between normal and affected sides in both phases. However, R-values increased in the postsurgery phase. Patients monitored postsurgery at 2 weeks, 3 months, and 6 months showed no complications. The 3D-printed patient-specific implants, customized to individual fracture shapes and featuring distinct implants and locking parts with notches, effectively restore bony orbital volumes and reduce exophthalmos. They have been proven feasible and applicable for reconstructing acute orbital wall fractures.
期刊介绍:
The Journal of Craniofacial Surgery serves as a forum of communication for all those involved in craniofacial surgery, maxillofacial surgery and pediatric plastic surgery. Coverage ranges from practical aspects of craniofacial surgery to the basic science that underlies surgical practice. The journal publishes original articles, scientific reviews, editorials and invited commentary, abstracts and selected articles from international journals, and occasional international bibliographies in craniofacial surgery.
