Orbital Roof and Lateral Wall Reconstruction Using Split-Thickness Calvarial Bone Graft with Titanium Mesh Complex for a Spheno-Orbital Meningioma
Keywords:orbit, sphenoid wing meningioma, calvaria, bone grafting
Objective: To describe our reconstruction of an orbital roof and lateral wall defect using a split- thickness calvarial bone graft with titanium mesh complex after resection of a meningioma of the left greater wing of the sphenoid with extension to the left frontotemporal bone and left orbital roof and lateral wall.
Study Design: Surgical Innovation
Setting: Tertiary Private University Hospital
Results: A 44-year-old woman with a left frontotemporal mass associated with left eye proptosis and epiphora underwent reconstruction of the left orbital roof and lateral wall defect using split-thickness calvarial bone graft with titanium mesh and screws after a left frontotemporal craniectomy, superior and lateral orbital wall resection of a mass of the sphenoid wing with orbital and frontotemporal extension. Final histopathology was consistent with meningioma. Surveillance of the mass and orbital reconstruction showed evidence of bone growth and osteointegration of the titanium mesh into the bone grafts.
Conclusion: The initial good outcome of orbital roof and lateral wall reconstruction using split-thickness calvarial bone graft with titanium mesh is evidenced by osteointegration of the titanium mesh and revascularization leading to new bone growth. This autogenous-alloplastic complex may provide a more stable option for orbital reconstruction, but long term follow-up is needed for surveillance of recurrence and monitoring the status of orbital reconstruction.
