Abstract

Enophthalmos is a common result of orbital fractures and zygomatic fractures. Reconstruction of the orbita is very important, because enophthalmos leads to not only functional but also cosmetic problems. We have experienced cases in which the eyeball became recessed following an operation or trauma. Even when we performed an overcorrective reconstruction surgical procedure, several patients showed tardive enophthalmos. The purpose of this study was to investigate the changes in eyeball position after operation or trauma. We measured the degree of eyeball displacement in 16 patients by using computed tomographic data collected immediately after operation and at one year. In 12 patients, enophthalmos was progressed, and the average change was 1.38mm. We propose that the progression of enophthalmos was primarily caused by atrophy and cicatrisation of the soft tissue of the orbita. This change in the soft tissue is the result of traumatic hemorrhage, edema and the operative procedure. These findings suggest that we should perform an even more overcorrective reconstruction surgical procedure than in the past.
