[Reconstructive surgery of the orbit and adjacent paranasal structures (author's transl)].

In reconstruction of the orbital floor, homograft lyophilised dura or cialit-stord rib cartilage are suitable, but the best materials are autologous cartilage or silastic or teflon. Autograft bone from the maxilla or rib is rarely used. The surgery of traumatic hypertelorism and the reconstruction of the medial angle of the eye after orbito-nasal fractures are described and illustrated. With complete destruction of the floor of the orbit, a fronto-temporal pedicled flap combined with auricular cartilage is recommended. In this way, the orbital floor and the lower eyelid can be reconstructed. The epithelial lining of the orbit can be developed from a pedicled flap of maxillary sinus mucus membrane.
