Summary
Orbital schwannoma, a rare tumor, can cause recurrent ptosis and diplopia. Surgical removal via a vertical lid-split incision is effective for superior orbital lesions.
Area of Science:
- Ophthalmology
- Neurology
- Neurosurgery
Background:
- Orbital schwannomas are rare tumors.
- Diagnosis can be challenging due to slow growth and varied presentations.
- Ptosis is an uncommon initial symptom.
Observation:
- A 50-year-old male presented with recurrent unilateral ptosis.
- Initial levator palpebrae resection failed to resolve the ptosis.
- Acute diplopia led to MRI, revealing a superior orbital lesion with orbital roof dehiscence.
Findings:
- The orbital lesion was identified as a schwannoma.
- The frontal lobe was observed protruding through the orbital roof defect.
- Surgical excision was performed using a vertical lid-split incision.
Implications:
- This case underscores the need for diagnostic vigilance with recurrent ptosis.
- The vertical lid-split approach is valuable for anterior superior orbital lesions.
- Early and accurate diagnosis of orbital schwannoma is crucial for effective treatment.

01:14Cranial Bones: Superior and Posterior View
2.5K
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,...

01:27Cranial Bones: Lateral View
2.4K
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...

01:22Sutures of the Skull
7.1K
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...
