OBJECTIVE To describe an adaptable method for reconstruction of the orbit following partial orbitectomy. METHODS One horse, one cat, and four dogs. METHODS Following partial orbitectomy for removal of bone and soft tissue affected by pathologic processes, reconstruction was achieved. Cerclage wires were used to reconstitute the orbital rim and other salient facial contours involved in excisions. These wires were then covered with a prolene mesh, first inside the orbit and then outwards over the affected extraorbital areas. Thereafter, a collagen sheet was placed over the mesh. Finally, subcutis and skin were closed over the construct. RESULTS All operated eyes remained visual with normal position, direction, and mobility. Eyelid function, tear production, and nasolacrimal function were preserved. Side effects were mild and temporary, but animals requiring a lateral-posterior surgical approach experienced concavity to the side of the head posterior to the orbital ligament region. One bone tumor out of three recurred. CONCLUSIONS The reconstruction method presented offers excellent results tectonically, cosmetically, and functionally, even following extensive orbitectomy. By adapted application of three reconstruction steps using readily available materials, large defects may be surgically repaired. Once orbitectomy is mastered, reconstruction requires no additional specialized techniques or equipment.

D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.
