Abstract
Objective: We have previously published an endonasal endoscopic technique of inferior orbital floor reconstruction, for the surgical management of the “silent sinus syndrome” and “blow-out” orbital fractures. Based on the same principles, we present an alternative version of the technique with the advantage of an “overlay” approach to the bone defect. Method: After creating a large middle meatal antrostomy, an autologous septal bone graft is placed over the orbit floor defect, in the subperiostal plane between orbital contents and bony floor, through an incision on the lamina papyracea. Results: At long-term follow-up we achieve, in most, if not all, cases, resolution of enophthalmos and ipsilateral chronic maxillary sinus atelectasis, with minimal morbidity. Conclusion: This technique provides excellent functional and aesthetic results in the surgical reconstruction of the orbit floor.
