Objective To repair secondary orbital zygomatic depression and conjunctival sac stenosis or atresia after enucleation and radiotherapy in order to reshape the middle facial contour and place the prosthetic eye. Methods Incision was made by temporal hairline incision. The conjunctival sac was reconstructed with pedicle flap pedicled behind the ear. The preformed hydroxyapatite block was filled into the orbital zygomatic depression. The superficial temporal pedicel fascia flap covered the surface of the implant block and the shape was improved. The results of a reconstruction of 16 cases, 2 to 3 weeks after the placement of the eye, facial symmetry, good shape. Conclusions Tissue flap and artificial bone can repair radioactive orbital conjunctival sac deformity in one phase, and good results can be obtained.
