Fig. 11. A. Lateral canthotomy incision is made with straight iris scissors. B. Periosteum is elevated off of the lateral orbital rim. C. Wide undermining allows retraction of the skin incision to permit superior and inferior osteotomies to be made with the air-driven saw. D. The bony rim has been outfractured. Because of the distensibility of the skin, it is possible to remove a large bone flap through the small canthotomy incision. E. The intraconal mass is extracted with the aid of the cryoprobe. F. The bone fragment is positioned for resuturing.
