Summary
Analyzing sphenoid wing meningioma (SWM) growth patterns revealed that specific bone infiltration predicts recurrence. Understanding these anatomical patterns aids surgical strategy and patient prognosis for SWM.
Area of Science:
- Neurosurgery
- Radiology
- Oncology
Background:
- Complete resection is vital for managing sphenoid wing meningiomas (SWM).
- Predicting recurrence and prognosis in SWM is challenging.
- Anatomical growth patterns may offer predictive insights.
Purpose of the Study:
- To analyze the extension patterns of sphenoid wing meningiomas (SWM).
- To correlate SWM growth patterns with intraoperative findings, extent of resection, and recurrence rates.
- To identify anatomical predictors for SWM recurrence and prognosis.
Main Methods:
- Utilized MRI for soft tissue and CT scans for bone extension analysis.
- Quantified soft tissue spread using four and bone infiltration using eight anatomical landmarks.
- Assessed extent of resection using Simpson classification (grade I-V) and correlated with growth patterns and recurrence.
Main Results:
- Included 44 patients (37 female, 7 male); 29.5% experienced recurrence.
- Recurrent tumors were associated with significantly worse Simpson scores (p=0.01).
- Cavernous sinus soft tissue spread and superior orbital fissure bone infiltration correlated with poor Simpson grades (p=0.001).
- Orbital roof superior orbital fissure bone infiltration strongly predicted tumor recurrence (p=0.002).
Conclusions:
- Structured radiological and anatomical analysis of SWM growth patterns is crucial.
- These analyses can influence surgical strategy for SWM.
- Growth pattern assessment facilitates improved management and prognostication of SWM patients.

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...

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...
