The "Hourglass Facial Deformity" is the result of bilateral irradiation of the orbits and anterior cranial base during infancy. The deformity is uniformly characterized by a distinctly misshapen upper face at the level of the orbits, with depression of the temporal region, hypotelorism, and flattened nasal root. These patients exhibited varying degrees of frontal bossing. Since they had previous enucleation, the orbital soft-tissue can be dissected off the eye socket, lateral orbital walls, and if necessary, the orbital cone, through a bicoronal incision. The deformity is then easily corrected with implantation of acrylic alloplastic material. Four cases are presented which had varying degrees of the same deformity and were successfully corrected using the operative procedure described. No complications have been encountered. Two patients required eye socket revisions.
“沙漏脸畸形”是婴儿期双侧眼眶和前颅底接受放射治疗的结果。这种畸形的特征一致，表现为眼眶水平的上脸明显畸形，颞部凹陷、两眼间距过窄以及鼻根扁平。这些患者有不同程度的额部隆突。由于他们之前已行眼球摘除术，可通过双冠状切口将眼眶软组织从眼眶、外侧眶壁，必要时从眶锥分离。然后通过植入丙烯酸类异体材料很容易矫正畸形。本文介绍了4例有不同程度相同畸形且使用所述手术方法成功矫正的病例。未出现并发症。2例患者需要进行眼眶修复。
