Summary
The pre-auricular lateral subtemporal approach is effective for treating extensive angiofibroma with skull base invasion. This surgical technique achieved complete tumor removal with no complications in pediatric patients.
Area of Science:
- Neurosurgery
- Otolaryngology
- Pediatric Oncology
Background:
- Extensive angiofibroma with intracranial extension presents surgical challenges.
- Skull base surgery advancements enable effective treatment of these complex tumors.
Purpose of the Study:
- To evaluate the efficacy of the pre-auricular lateral subtemporal approach for extensive angiofibroma with intracranial extension (Radkowski staging IIIb).
Main Methods:
- Retrospective analysis of seven pediatric patients with Radkowski staging IIIb angiofibroma.
- Four patients underwent surgical resection: three via pre-auricular lateral subtemporal approach, one via maxillary swing approach.
- Preoperative embolization was performed in all surgical cases.
Main Results:
- Gross total tumor removal was achieved in all three patients who underwent the pre-auricular lateral subtemporal approach.
- No permanent complications were observed in these patients.
- Follow-up of at least one year showed no tumor recurrence.
Conclusions:
- The pre-auricular lateral subtemporal approach offers a direct and shallow route for skull base tumor visualization and resection.
- This approach is recommended for treating angiofibroma with Radkowski staging IIIb due to its effectiveness and safety.
