Summary
Endoscopic microvascular decompression (MVD) with transposition is a feasible minimally invasive surgical technique. This approach offers excellent visualization, protecting vital perforators and improving outcomes for trigeminal neuralgia and hemifacial spasm.
Area of Science:
- Neurosurgery
- Minimally Invasive Surgery
- Endoscopic Techniques
Background:
- Endoscopic microvascular decompression (MVD) provides clear visualization for treating trigeminal neuralgia and hemifacial spasm.
- Transposition techniques aim to improve surgical outcomes by preventing adhesions and granulomas.
- This study evaluates the feasibility and effectiveness of transposition within endoscopic MVD.
Observation:
- A retrosigmoid keyhole approach was used for fully endoscopic MVD with 0- and 30-degree endoscopes.
- A bimanual technique with a pneumatic holding system facilitated instrument manipulation.
- Transposition was achieved using Teflon felt string and fibrin glue.
Findings:
- The 30-degree endoscope clearly visualized neurovascular conflicts and perforators, even behind corners.
- Transposition of the offending artery was safely performed, preserving critical perforators.
- Patients experienced symptom improvement without permanent complications.
Implications:
- Endoscopic MVD combined with transposition is a viable surgical option.
- Enhanced visualization protects perforators, potentially leading to better surgical results.
- This technique is expected to yield excellent outcomes for patients undergoing MVD.
