Reconstruction of Orbital Floor Fractures with Autogenous Bone Graft Application from Anterior Wall of Maxillary Sinus: A Retrospective Study

Introduction

Orbital wall fracture implies a situation where disruptions of the walls or floor have occurred. It is a blowout type fracture where bone fragments with torn periosteum are pushed outside of the original bony orbit. There is no intact bone even near the defect area except the thin bone rim surrounding the blowout fracture. The purpose of this defect repair is to support orbital contents, free entrapped tissue, and, especially, restore the original orbital volume.

Material and methods

Ten patients (seven males and three females) who underwent repair of orbital floor factures with maxillary sinus bone grafts were included in this study. Surgical procedure for harvesting graft and its fixation was almost same in all operated cases.

Conclusion

The collection in the maxillary sinus due to fracture of floor of orbit, blood and bony fragments collected in the maxillary sinus can be easily drained and removed after removal of anterior wall of maxillary sinus and through the same approach you can reduce the floor of orbit manually to the proper position which helps to decease the orbital floor defect.
