Orbitofrontal bone dysplasia, a newly identified condition causing ocular dystopia and frontal bone defects, can be effectively treated with single-stage fronto-orbital reconstruction, preserving vision.
Area of Science:
- Craniofacial Surgery
- Pediatric Plastic Surgery
- Congenital Abnormalities
Background:
- Orbital dysplasia and frontal bone defects are observed in patients with ocular dystopia and craniofacial differences.
- This condition is distinct from other diagnoses like encephalocele or craniofacial dysostoses.
Purpose of the Study:
- To identify and characterize a previously unreported condition of orbitofrontal bone dysplasia.
- To evaluate the efficacy of fronto-orbital reconstruction for this condition.
Main Methods:
- Retrospective review of craniofacial registries from 2000-2014.
- Analysis of features and treatment outcomes in four patients with congenital orbitofrontal bone dysplasia.
Main Results:
- Four patients identified with unilateral or bilateral frontal bone defects and ocular dystopia.
- Fronto-orbital reconstruction using cranial bone grafting successfully reduced ocular dystopia and preserved vision in three patients.
Conclusions:
- Orbitofrontal bone dysplasia is a novel condition characterized by frontal bone defects and ocular dystopia.
- Single-stage fronto-orbital reconstruction is an effective treatment for this condition.

Association Areas of the Cortex
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
