Objective: To investigate the effect of keyhole surgery under the microscope on the neurologic function and prognosis of patients with intracranial small meningioma, and to verify the clinical efficacy of keyhole surgery under the microscope. 

Methods: As research subjects, 62 patients admitted to our hospital from January 2016 to December 2018 were included. They were divided into a control group and an observation group. The clinical data for the two groups of patients were analysed retrospectively. Patients in the control group underwent routine craniotomy. Observation group patients underwent keyhole surgery under the microscope. The postoperative neurological function and prognosis of the two groups of patients were compared and analysed, to verify the effects of keyhole surgery under the microscope in the treatment of intracranial small meningioma. The blood loss and operation time of the two groups of patients were also compared. In addition, the neurological function, complications, and prognosis of patients after operation were compared. 

Results: The results showed that the patients in the control group experienced more intraoperative blood loss and longer operation times. The probability of postoperative complications was also found to be higher. The neurological function and prognosis of the observation group were significantly better than those of the control group. In the observation group, patients who underwent keyhole surgery under the microscope, neurologic function was less affected, and the operation was smoother. The prognosis and complications were also significantly better than those of the control group. The difference between the two groups was statistically significant (p<0.05). 

Conclusion: Keyhole surgery under the microscope has significantly better effects than routine craniotomy on the treatment of intracranial small meningiomas. Keyhole surgery optimizes the surgical procedure, reduces the risk of complications, reduces the impact on the patient’s neurologic function, and yields improved prognosis.
