Abstract: Objective: To analyze the clinical characteristics and pathological types of posterior fossa tumors in children, and discuss related problems about surgical methods and surgical treatment.Methods: Clinical data on 58 patients with posterior fossa after surgery were retrospectively analyzed. Results: Children with intracranial tumors were more common in male, less in female. The Pathological diagnoses of brain tumor included medulloblastoma, ependymoma and astrocytoma. Clinical manifestations were determined by age and location of the tumors. Surgical approaches included craniotomy through suboccipital opening via middle road for the fourth ventricle and cerebellar vermis tumors, paramedian opening for cerebelar hemisphere tumors, and retrosigmoid approach for cerebellopontine angle area tumors. . Conclusion: Surgical resection is the main treatment of posterior fossa tumors. Proper operation method based on tumor locations and the specific situations can reduce the occurrence of postoperative complications. Malignant tumors often need radiotherapy, and chemotherapy after surgery.
