Summary
The trans-supraorbital approach provides wide exposure for treating supratentorial aneurysms with minimal brain retraction. This keyhole modification offers safe and effective surgical options with successful patient outcomes.
Area of Science:
- Neurosurgery
- Cranial Base Surgery
- Microsurgery
Background:
- The trans-supraorbital approach merges keyhole principles with cranial base surgery.
- Previous studies demonstrated visualized anatomic fields in cadavers.
Purpose of the Study:
- To describe the trans-supraorbital approach for intracranial supratentorial aneurysms.
- To detail the advantages and surgical applications of this technique.
Main Methods:
- The trans-supraorbital approach was utilized in 22 cases of supratentorial aneurysms.
- A 3.5-cm craniotomy with orbital arch extension and orbital roof drilling was performed.
Main Results:
- The technique provided wide exposure of neurovascular structures with minimal cerebral retraction.
- All 22 patient outcomes were successful, with no serious complications.
- Improved microscopic illumination and access to the supratentorial vascular territory were noted.
Conclusions:
- The trans-supraorbital approach is effective for accessing and treating supratentorial aneurysms.
- This modification of the keyhole procedure offers convenient microsurgical fields and multiple surgical options.
