Microorbitalism: a technique for orbital rim expansion.

Abstract

A simple technique for orbital aperture expansion to facilitate placement of ocular prostheses is described. Both superolateral and inferolateral orbital margins are released by means of a single burr hole craniectomy of the frontosphenoid bone behind the orbital process of the frontal bone. Vertical and horizontal marginal lengthenings are performed by a rotatory displacement of one bone segment alongside the other. The expanded osseous aperture is secured with wire and plate-and-screw fixation following a supraorbital rim craniectomy to allow an adequate fit. The result provides for easier access of ocular prostheses and tissue expanders. The method has been applied to a series of patients with microorbitalism due to unilateral or bilateral congenital anophthalmia over the past 3 years without complication and with excellent results. Three-dimensional re-formatted CT reconstructions of the craniofacial skeleton are shown preoperatively and postoperatively.
