Abstract：Objective To investigate the feasibility, advantage and significance of no continuous traction in resection of central neurocytoma in the lateral ventricle. Methods Clinical data of 36 patients with central neurocytoma in the lateral ventricle were analyzed retrospectively, including 25 main tumors near to the interventricular foramen and 11 in the body of lateral ventricle. Thirty-one patients underwent surgery via the transcortical frontal horn approach and 5 via interhemispheric transcallosal approach. The brain self-retaining retractor or continuous traction with a brain spatula were not allowed during the surgery. The extent of tumor resection, postoperative neurological deficits and complications were evaluated. Results Total resection was achieved in 35 patients and subtotal resection in 1 patient. Immediate postoperative complications included paralysis in 4 patients, slow reaction in 10 and memory deterioration in 13. All the patients with paralysis recovered in 2 weeks after surgery, and the reaction and memory were improved in 1 month after surgery. The postoperative hydrocephalus occurred in 2 patients (5.6%), who had spontaneous remission 3 month after surgery. There were no intracranial hematoma, subdural effusion and subcutaneous hydrops. All the patients were followed up for 1 to 3 years and no tumor relapse occurred. Eight patients received radiotherapy. Conclusions Application of no continuous traction in the resection of central neurocytoma in the lateral ventricle can expose the tumor completely and make the operation convenient. And this technology could decrease the occurrence of postoperative neurological deficits secondary to the retraction injury.
