Summary
A novel en bloc bifrontal craniotomy technique offers improved access to anterior skull base tumors. This method enhances surgical approach without retracting frontal lobes, benefiting craniofacial resection procedures.
Area of Science:
- Neurosurgery
- Surgical Oncology
- Skull Base Surgery
Background:
- Combined craniofacial resection is standard for ethmoid bone and anterior skull base tumors.
- The transbasal approach can be enhanced by mobilizing the medial fronto-orbital ridge using a monobloc bone flap.
Purpose of the Study:
- To describe a novel en bloc bifrontal craniotomy technique.
- To demonstrate its advantages for accessing the anterior skull base.
Main Methods:
- An en bloc bifrontal craniotomy was performed, incorporating the supraorbital ridges and nasal bones.
- This was achieved via extensive periosteal dissection in the coronal scalp area, avoiding facial incisions.
Main Results:
- The described technique provides a wider surgical angle to the anterior skull base compared to existing methods.
- It effectively avoids the need for frontal lobe retraction during the procedure.
Conclusions:
- The en bloc bifrontal craniotomy is a valuable advancement for craniofacial resection.
- This approach offers superior exposure and minimizes complications associated with frontal lobe retraction.
