Summary
Horizontal osteotomy provides wide surgical access to the central skull base and clivus. This approach enhances tumor removal while preserving function and cosmetic outcomes.
Area of Science:
- Neurosurgery
- Surgical Oncology
- Anatomy
Background:
- Tumor resection in the central skull base presents challenges due to limited surgical access.
- Minimally invasive techniques are crucial for preserving neurological function and cosmetic appearance.
Purpose of the Study:
- To evaluate the efficacy of horizontal osteotomy for central skull base tumor resection.
- To assess the extent of surgical exposure and complication rates associated with this technique.
Main Methods:
- A horizontal osteotomy of the maxilla was performed to facilitate down-fracture.
- The surgical approach was extended posteriorly to include the clivus and C1 arch.
- Tumor removal was performed with a focus on achieving wide operative exposure.
Main Results:
- The horizontal osteotomy provided extensive anterior (8 cm) and posterior (5 cm) exposure of the central skull base.
- The technique allowed for safe down-fracture of the maxilla.
- A low rate of complications was observed.
Conclusions:
- Horizontal osteotomy is an effective surgical approach for central skull base tumors.
- This method offers superior functional and cosmetic preservation.
- The technique provides wide operative exposure with minimal complications.
