Neuronavigation-guided 3D neurovascular reconstruction has shown promising results in the treatment of trigeminal neuralgia and hemifacial spasm, allowing for better identification and reduction of nerve and blood vessel compression.
Object:Microvascular decompression (MVD) is the best curative treatment for trigeminal neuralgia and hemifacial spasm. We used the neuronavigation to reconstruct the 3D image of cranial nerve and blood vessel to identify the neurovascular compression, and to reconstruct the venous sinus and skull to optimize craniotomy.Patients and Methods:A total of 11 trigeminal neuralgia and 12 hemifacial spasm cases were selected. All patients had preoperative MRI which included 3D Time of Flight (3D-TOF), Magnetic Resonance Venography (MRV) and computer tomography (CT) for navigation. Imaging sequences were fused and reconstructed by navigation system before operation. The 3D-TOF images were used to delineate cranial nerve and vessel. The CT and MRV images were used to mark transverse sinus and the sigmoid sinus for craniotomy. All patients underwent MVD and have the preoperative view compared with intraoperative findings.Results:Approaching to the cerebellopontine angle right after opening the dura and got no cerebellar retracion or petrosal vein rupture during craniotomy. Ten of 11 trigeminal neuralgia and all 12 hemifacial spasm patients got excellent preoperative 3D reconstruction fusion images, which were also confirmed by intraoperative findings. All 11 trigeminal neuralgia patients and 10 of 12 hemifacial spasm patients were symptom free without any neurological complications just after the surgery. Other 2 hemifacial spasm patients got delayed resolution in 2 months after surgery.Conclusions:Through the neuronavigation guided craniotomy and the 3D neurovascular reconstruction, surgeons can better identify the compression of nerve and blood vessel, and reduce complications.
