Infraorbital and zygomatic reconstruction procedures pose challenges to plastic surgeons because of the close location of the operation to the eyes and nose. Failed flap design can lead to distortion of the adjacent organs and tissue, particularly for larger defects. Flaps based on the orbicularis oculi muscle (OOM) can be easily rotated from the lateral or temporal region to cover the infraorbital and zygomatic area. We use a soft-tissue expander to enlarge the size of this flap for larger defect repair. Out of a total of 12 patients whose infraorbital or zygomatic defects ranged from 2.0 × 3.0 cm to 4.0 × 5.0 cm, 11 experienced a successful repair without complications. The size of the pre-expanded rotation flap ranged from 3.0 × 4.0 cm to 5.0 × 7.0 cm. The pre-expanded rotation flap based on the OOM has the advantages of an excellent colour and thickness match to the infraorbital and zygomatic areas, a reliable blood supply, abundant tissue and negligible donor-site morbidity. It has thus become our favourite technique for infraorbital and zygomatic reconstruction.
眶下和颧骨重建手术对整形外科医生来说具有挑战性，因为手术部位紧邻眼睛和鼻子。皮瓣设计不当可能导致邻近器官和组织变形，尤其是对于较大的缺损。基于眼轮匝肌（OOM）的皮瓣可以很容易地从外侧或颞侧旋转覆盖眶下和颧骨区域。我们使用软组织扩张器来扩大皮瓣的大小，以修复更大的缺损。在总共 12 名眶下或颧骨缺损范围为 2.0×3.0cm 至 4.0×5.0cm 的患者中，11 名患者成功修复且无并发症。预扩张旋转皮瓣的大小范围为 3.0×4.0cm 至 5.0×7.0cm。基于 OOM 的预扩张旋转皮瓣具有与眶下和颧骨区域颜色和厚度极佳匹配、可靠的血液供应、丰富的组织和几乎不影响供区的优点。因此，它已成为我们进行眶下和颧骨重建的首选技术。
