The Role of Orbital Buttress for Treatment of Post-Traumatic Enophthalmos and Thyrotoxie Exophthalmos

摘要

The orbital buttress plays an important role in maintenance of the thin medial and inferior orbital wall. Severe post-traumatic enophthalmos is often seen in extensive destructed cases of orbital buttress. We inserted one or two absorbable screws in the site of orbital buttress, and bone grafting was placed above them. The grafted bone was stable, and enophthalmos was well repaired postoperatively. In contrast, we performed orbital wall decompression with wide resection of the orbital buttress in the patients with thyrotoxie exophthalmos. To avoid post-operative complications, orbital periosteum was preserved as much as possible and orbital fat was resected minimally. Management of orbital buttress is emphasized to be the key of orbital surgery.
