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.
描述了一种用于眼眶孔径扩大以促进眼假体植入的简单技术。通过在额骨眶突后方的额蝶骨进行单孔开颅切除术来松解眶上外侧和眶下外侧边缘。通过一个骨段沿另一个骨段的旋转移位来进行垂直和水平边缘延长。在眶上缘开颅术后，用钢丝以及钢板和螺钉固定来固定扩大的骨孔，以确保合适的贴合度。该结果使眼假体和组织扩张器更容易置入。在过去3年中，该方法已应用于一系列因单侧或双侧先天性无眼球导致小眼眶症的患者，无并发症且效果极佳。展示了颅面骨骼术前和术后的三维重新格式化CT重建图像。
