Reconstruction of the anophthalmic orbit by orbital osteotomy and free flap transfer.
It is challenging to perform an adequate reconstruction of the post enucleation irradiated orbit of patients with rentinoblastoma. Rebuilding of the orbital structure, reconstruction of the eye socket and restoration of periorbital volume are required. We reviewed 12 patients with hypoplastic orbital deformities, who have undergone orbital osteotomy and free flap transfer. Reconstruction of the orbital cavity was achieved using 'C' osteotomy of the lateral portion of the orbit in mild and moderate cases or transverse 'U' osteotomy of lateral wall, roof, and floor by intra-cranial approach in severe cases. Socket reconstruction and periorbital volume restoration was achieved using dorsalis pedis free flap transfer. From our experience the combination of orbital osteotomy and free flap transfer could meet the multi-requirements for the anophthalmic orbital reconstruction, including both orbital bony enlargement and soft tissue restoration.
