Exenteration of the orbit using a frontal periosteal flap

The technique of exenteration of the orbit described is used for orbital malignancies confined to the orbit without lid involvement and without overt evidence of metastases. The exenterated orbit is covered by a periosteal flap derived from the frontal bone. The procedure is simple, shortens the duration of the operation and allows for both pre- and postoperative radiotherapy. The procedure is particularly useful in children because of the minimal blood loss compared with exenteration using a temporalis muscle flap.
