Clinical Efficacy of Neuroendoscope-assisted Microsurgery Through an Anterior Transpetrosal Approach in the Treatment of Meningiomas

Objective: This study probed the clinical efficacy of neuroendoscope-assisted microsurgery through an anterior transpetrosal approach in the treatment of meningiomas.Methods: In this study, we retrospectively analyzed 31 patients with meningiomas who underwent neuroendoscope-assisted microsurgery, operated using the anterior transpetrosal approach, from September 2020 to October 2023.Results: The tumor was totally resected in 5 patients, subtotally resected in 23 patients, and mostly resected in 3 patients.There was one case of postoperative trochlear nerve injury and one case of mild facial paralysis.All patients had no postoperative cerebrospinal fluid leakage or intracranial hemorrhage, with normal hearing.No recurrence or death occurred at the 1-month postoperative follow-up.Conclusion: Neuroendoscope-assisted microsurgery through the anterior transpetrosal approach yields satisfactory clinical outcomes in the treatment of meningiomas, as evidenced by alleviated symptoms, reduced serious postoperative complications, recurrence, and mortality, and increased quality of life of patients with high patient satisfaction.
