ABSTRACT
OBJECTIVE@#To evaluate the feasibility of surface tractotomy of trigeminal nerve sensory root (STS) for the treatment of trigeminal neuralgia (TN).@*METHOD@#Seven patients with TN were operated on using the STS. The six patients were followed up for 4.8-9.8 years. The trigeminal nerve root (TNR) obtained from 30 cadavers were performed microanatomical research using paraffin embedding and hematoxylin-eosin staining technique.@*RESULT@#Clinically, the patients' symptoms, such as face ache, disappeared after the surface nerve fiber bundles of trigeminal nerve sensory root (TNSR) were cut off. Only one patient died of brainstem bleeding on postoperative day 18. Histological examination The common type of sensory root fibers were arranged parallel for 3-6 mm at its exit of brainstem, and then the glial myelin transformed to Schwann cells. The axon bifurcated from outer layer to middle region, and gradually formed the tiny nerve fiber bundles in the surface layer and the giant nerve fiber bundles in the center of the root.@*CONCLUSION@#TN can be radical cured by STS without lesioning of nerve functions. Therefore,this new approach is an effective, advanced surgical technique for TN treatment.
