Abstract
Injuries to the inferior and lateral orbital walls are traditionally classified as either "blow-out" or trimalar fractures. This simplified system has helped considerably in the understanding of the causes of the two types of injury and methods of repair. Unfortunately, simultaneous occurrence can cause immediate and delayed problems that potentiate each other. Enophthalmos and globe ptosis, in combination with a depressed malar eminence, present a major challenge to the reconstructive surgeon's efforts to achieve satisfactory function and appearance. This paper reports the results of combined orbital floor and lateral wall injuries as an important clinical trauma syndrome. The interaction of the two fractures with regard to pathophysiology, sequelae, and methods of correction will be discussed. A review of cases will be used to describe the authors' techniques of repair, and to illustrate the preferred methods of bone grafting for correction of retrusion and depression of the globe, muscle entrapment and depression of the malar eminence.
