Trigeminal nerve transposition by sling-pulling technique in combination with macrovascular transposition for giant basilar artery–induced trigeminal neuralgia via a combined transpetrosal approach
To describe a novel surgical technique specifically for treating trigeminal neuralgia (TGN) caused by a gigantic dolichoectatic vertebrobasilar artery (DBA) using a combined transpetrosal approach.
Key Findings:
The sling-pulling technique allowed for effective transposition of CN5 and DBA, with metrics indicating superior outcomes compared to standard techniques.
Postoperative follow-up showed pain-free status at 20 months.
Facial palsy resolved completely within 4 months, while mild hypoesthesia persisted.
Interpretation:
The combined transpetrosal approach with the sling-pulling technique effectively alleviated TGN symptoms caused by a gigantic DBA, demonstrating a potential surgical solution for complex cases and highlighting the innovative nature of this technique.
Limitations:
The rarity of DBA-induced TGN limits the generalizability of the findings.
Long-term outcomes beyond 20 months are not reported, and potential biases in patient selection may exist.
Conclusion:
The novel surgical approach provides a promising option for patients with DBA-induced TGN, emphasizing the importance of adequate decompression and nerve transposition, and suggesting further research to validate these findings.
