PROBLEM: This study explores contribution of the orbital floor to mechanical outcomes of orbital decompressions. METHOD OF STUDY: Endoscopic medial wall orbital decompressions with and without extensive medial orbital floor removal (OFR) were performed on opposite sides of ten thawed fresh-frozen cadaver heads Bone removal was compared on pre- and post-dissection CT scans and after orbital exenteration. RESULTS: Bony removal in the anterior orbital apex was significantly better after OFR (117 vs 66, p 60% more orbital bone and an additional 51 of orbital apex bone. Extensive endoscopic removal of the mid-portion of the medial orbital floor results in bone loss beneath the globe itself.
