title: A surgical treatment of severe late posttraumatic enophthalmos using sliced costal cartilage chip grafts.
abstract: The efficacy of sliced costal cartilage chip grafts for the treatment of late posttraumatic enophthalmos was investigated. Surgery was conducted based on the method reported by Matsuo et al. in 1989. After making an incision in the lower eyelid, dissecting the subperiosteum of the medial orbital wall, orbital floor and lateral orbital wall was performed to the posterior of the orbit, and then costal cartilage chips were gradually grafted in a step-like configuration to the subperiosteum from a location posterior to the equatorial plane of the eyeball. At this time, as well as to the area of concave depression in the orbital bone caused by the fracture, grafts were made to the subperiosteum of the non-deformed medial and lateral orbital wall, to move all of the orbital tissue, including the eyeball, forward. This was performed for five cases of severe late posttraumatic enophthalmos. Among the five cases, there were four cases of severe orbital fracture and one case for which malignant orbital tumor extirpation and radiation therapy had been performed. Following surgery, although mild enophthalmos remained in three of the five cases, esthetically satisfactory results were obtained for all cases. Costal cartilage chip grafts were shown to be an effective method for the treatment of late posttraumatic enophthalmos.
