Summary
This 15-year study analyzed orbital tumors, finding distinct patterns in children versus adults. Optic nerve gliomas and retinoblastomas were common in children, while basal cell carcinomas and meningiomas predominated in adults.
Area of Science:
- Ophthalmology
- Pathology
- Oncology
Context:
- Orbital tumors represent a diverse group of neoplasms affecting the eye socket.
- Understanding the epidemiological characteristics of orbital expansive processes is crucial for diagnosis and treatment planning.
Purpose:
- To describe orbito-sphenoidal expansive processes diagnosed over 15 years.
- To evaluate the relative frequencies of orbital tumors compared to other neoplastic conditions.
Summary:
- A 15-year retrospective analysis identified 82 cases of orbital expansive processes.
- Orbital tumors constituted 0.8% of all tumors diagnosed between 1976-1980.
- Children showed higher rates of optic nerve gliomas, retinoblastomas, and rhabdomyosarcomas, whereas adults more frequently presented with basal cell carcinomas, squamous cell carcinomas, and meningiomas.
Impact:
- Anatomopathological studies are vital for accurate diagnosis and therapeutic strategies in orbital oncology.
- Epidemiological characterization of orbital tumors aids in understanding disease patterns and optimizing patient care.
- Advancements in ophthalmic pathology contribute to improved diagnostic accuracy and understanding of orbital disease mechanisms.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
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,...

01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
