Computer-Assisted Three-Dimensional Planning for Orbital Decompression.

Thyroid-associated orbitopathy is the most common cause of unilateral or bilateral proptosis in adults. A mainstay of surgical treatment is orbital decompression utilizing osteotomies to increase the size of the affected bony orbit to accommodate the larger soft tissue volume. Over the past several decades, numerous approaches have been described for orbital decompression. However, given the intricate osseous and soft tissue anatomy within the orbit, orbital decompression is a potentially hazardous intervention. With advances in three-dimensional imaging and virtual planning, extensive orbital decompressions can be performed safely and efficiently. In this report, we describe two cases of three-wall orbital decompressions using three-dimensional planning.

Acute Intraorbital Hemorrhage following Reduction of a Displaced Orbitozygomaticomaxillary Complex Fracture.

Orbitozygomaticomaxillary complex (OZMC) fractures are commonly encountered by the craniomaxillofacial trauma surgeon and may, in fact, be the most common type of orbital fracture. Disruption of articulation with the frontal and sphenoid bones causes disruption of the internal orbital skeleton, which can result in diplopia from extraocular muscle swelling or entrapment, or enophthalmos from increased orbital volume. Although there is significant energy transferred to the orbit in these injuries, blindness and intraorbital hematoma are, fortunately, relatively rare complications, typically seen pre- or postoperatively. In this report, we describe the development of acute intraorbital hemorrhage following reduction of a displaced OZMC fracture.
