    Objective: This study aimed to evaluate the feasibility and efficacy of one-piece resection for treatment of ventral intradural extramedullary spinal meningiomas (VIESMs).Methods: Between January 2017 and December 2023, all patients who underwent one-piece resection for VIESMs were retrospectively reviewed with their demographic, intraoperative and postoperative data being recorded. In addition, postoperative neurological status based on the modified McCormick functional schema (mMFS), along with radiological manifestations on the magnetic resonance imaging (MRI) were assessed and compared with that before operation.Results: A total of 27 cases (7 males and 20 females) with an average age of 63.37 ± 10.48 years old were included in the present study with the operation time, blood loss, length of hospital stay as well as follow-up periods being 292.41 ± 42.64 min, 286.85 ± 47.03 ml, 10.37 ± 1.69 days, and 16.81 ± 10.79 months, respectively. Postoperatively, one case experienced cerebrospinal fluid leakage without neurological deterioration. At the final follow-up, the scores of mMFS were unchanged in 7 (25.93%) cases while improved in the remaining 20 (74.07%) cases. Besides, the MRI examinations displayed that one-piece resection was successfully performed for each VIESM without a recurrence.One-piece resection was a feasible, safe and effective procedure of treating VIESMs. Partial removal of ipsilateral pedicle, facet joint, and even posterior vertebral wall to establish a wide surgical corridor and vision, resection of the dentate ligaments to minimize spinal cord traction, and meticulous coagulation of the dural attachment to reduce recurrence were the key technical points.
