The transantral approach of Ogura and Walsh is the most acceptable technique, since if allows the orbital contents to expand into maxillary and ethmoid sinuses which are the actual spaces. The authors presented two cases of Graves’ ophthalmopathy which underwent the orbital decompression by lateral rhinotomy approach. This approach provided a removal of the medial and lateral orbital wall as same as Ogura’ s technique. But our technique is more simple and more direct visualization of the surgical landmarks and does not need the microscope. By this way, the complications after orbital decompression could also be minimized and it yields a highly efficiency in reducing the malignant exophthalmos and should be further studied.
