Orbitofrontal Reconstruction With a Three-Dimensional Titanium Patient-Specific Implant After Intraosseous Haemangioma Resection


ABSTRACT

Background: Intraosseous hemangiomas are rare benign tumors that can develop in the skull. Orbitofrontal localization is uncommon. The complexity of orbitofrontal anatomy results in difficult reconstruction following trauma or tumoral resection.

Case presentation: A 50-year-old woman with a right orbitofrontal intraosseous hemangioma was referred to our department. The authors decided to perform tumoral bone resection and orbitofrontal reconstruction using virtual surgical planning in collaboration with Materialize engineers (Materialise, Leuven, Belgium). Three cutting guides and a patient-specific 3-dimensional (3D) titanium implant were designed and manufactured in 3 weeks. Surgery was performed with a double surgical team composed of maxillofacial surgeons and neurosurgeons. No perioperative or post-operative complications occurred. Post-operatively, the patient was completely asymptomatic and clinical examination showed symmetrical and satisfactory facial morphology.

Conclusion: Virtual surgical planning, design of patient-specific guides and manufacturing of implants make surgery easier and increase surgical precision. This technique is recommended for wide use in cases of oncological or complex trauma craniomaxillofacial reconstruction.
