Objective Periorbital fracture injury and tumor often cause the dislocation of periorbital bone and the eyeball , and further affecting appearance and vision. A safe and effective operation was developed and presented in this paper. Methods With osteotomy or excision, the fragment bone or tumor in the socket was removed to vacate the space for the normal position of the eye. Replace the eyeball back to its original normal position and implant autograft bone or artificial materials to the rest space. With this technique, we treated 2 cases of periorbital tumor, 4 cases of periorbital fractures. Results The two cases of benign tumor in the socket were excised completely with good contour. Of the 4 periorbital fractures, 3 obtained satisfactory results, 1 case had inner canthus ligament dislocation as the result of nasal fracture. Conclusion The restoration for orbital framework and eyeball dislocation is a very difficult subject. The technique introduced in this paper is practical and reliable for it.
