Summary
This study details a modified far-lateral transcondylar approach for removing hypoglossal neurilemmomas (HGNs). The technique proved effective, achieving high tumor removal rates with manageable patient morbidity.
Area of Science:
- Neurosurgery
- Oncology
- Cranial Nerve Surgery
Background:
- Hypoglossal neurilemmomas (HGNs) are rare tumors.
- Surgical removal is the primary treatment modality.
- The far-lateral transcondylar approach offers a corridor for accessing these tumors.
Purpose of the Study:
- To describe a modified far-lateral transcondylar approach for HGN resection.
- To evaluate the efficacy and safety of this modified surgical technique.
Main Methods:
- A modified far-lateral transcondylar approach was used in 11 consecutive patients with HGNs.
- Key steps include opening the hypoglossal canal and protecting the vertebral artery.
- Patient demographics, tumor characteristics, cranial nerve deficits, and outcomes were assessed.
Main Results:
- Gross-total resection was achieved in 10 of 11 patients.
- Common presenting symptoms included hypoglossal nerve deficits.
- Postoperative morbidity included transient cranial nerve palsies and swallowing difficulties in some patients.
Conclusions:
- The modified far-lateral transcondylar approach is effective for HGN removal.
- This technique achieves a high rate of gross-total tumor resection.
- The approach offers an acceptable morbidity profile for treating HGNs.
