Abstract

Study Design: A retrospective study of intradural extramedullary schwannoma. Objective: The purpose of this study was to compare treatment results in the differential surgery of intradural extramedullary schwannoma. Background: A reference guide to the surgical procedures available to treat intradural extramedullary schwannoma has not yet been established. Methods: The study retrospectively reviewed 110 patients: Group A: laminectomy+microscopic excision; Group B: hemilaminectomy+microscopic excision; Group C: laminectomy+microscopic excision+pedicle screw fixation. Researchers selected patients for this retrospective review by applying the following criteria: 1) back pain spread out from the tumor level, sensory and motor loss; 2) treatment by surgery; 3) clinical diagnosis made by physical examination, magnetic resonance imaging (MRI), and pathology; 4) a minimum clinical and radiologic follow-up of 12 months. The clinical outcomes were assessed by comparing the Visual Analogue Pain Scores (VAS) and the Japanese Orthopedic Association Scores (JOA score). The study also performed a cost-effectiveness analysis. Results: Cervical vertebrae: The estimated blood loss in Group B was significantly less than in Group C (P
