Two cases of orbital dystopia: Tessier III cleft and craniofacial osteomas

Two cases of orbital dystopia are reported. One was caused by a Tessier III cleft and was treated by cranio-facial osteotomies of three walls of the orbit, allowing the left to be moved upward. The second involved multiple craniofacial osteomas and was treated by extractional osteotomies of four walls of the orbit including a transverse split of the roof. These osteotomies were entirely extramucosal.
