title: [Materials used in reconstructive surgery of the orbit].
abstract: Orbital traumas and tumour operations may cause defects the operative management of which sets high requirements on the surgeon. For covering defects, transplants or implants are available. There is a risk of inflammation due to the free contact of the implants to the cavity of the inner nose or the sinus. Today, implants made from titanium, porous polyethylene, PDS (poly-p-dioxanon) foils, and ceramic materials are preferred. Alternatively, autogenous transplants can be used. These are immunologically harmless but they are of only limited availability. Moreover, a second operation for taking the transplants with creation of a donor defect is necessary.
