Orbital Roof Decompression and Transposition of Orbital Contents for Treatment of Orbital Deviation Associated With Fibrous Dysplasia.

A 25-year-old male was admitted to our institute complaining of caudal deviation of orbit. Surgery was performed through a coronal incision, a subtarsal incision, and a lynch incision. The periosteum of the orbital roof was raised, and the supraorbital wall was shaved cephalad in reference to the nonaffected side. Then the periosteum was incised from the inferior margin of the orbit to the medial and lateral palpebral ligaments, and the periosteum of the orbital floor was raised until the inferior orbital fissure. After the circumferential intraorbital periosteal detachment, the orbital contents could be readily moved cephalad ward. The outer table of the calvarial bone was transplanted to the orbital floor, and the palpebral ligaments were fixed 5 mm cranially. In the 5-year follow-up, the patient's visual function was normal, and no recurrence of fibrous dysplasia was observed.
