Reconstructive Surgery / Orbital Reconstruction

Orbital Reconstruction

Deformities of the orbit include:

1. Orbital dystopia-The bony orbital cavities do not lie in the same horizontal plane (Horizontal Dystopia) or the same vertical plane (Vertical Dystopia`).
2. Exorbitism- Normal orbital soft tissue exists (fat, muscles and the globe or eye) but a small bony orbit results in proptosis (eyes bulging). This may occur in patients with Crouzon, Apert and other syndromes.
3. Posttraumatic enophthalmos-Recessed globe (eye) results from discrepancy between the orbital volume and bony orbital cavity.

Correction of these deformities requires proper diagnosis and preoperative planning with the help of CT scans. Orbital bony and soft tissue reconstruction are often required. Surgical techniques used (many devised by Dr. Paul Tessier) include:

1. Box osteotomy
2. Facial bipartition
3. Midface Advancment
4. Repositioning of the sygomatic maxillary complex.

At the UCLA Craniofacial Clinic the decision as to which procedure(s) will be most effective in correcting a patient's orbital deformity depends on the patient's diagnosis, the severity of deformity and the team's evaluation.
