Does treatment result in the differential surgery of intradural extramedullary schwannoma of 110 cases? Context: A retrospective study of intradural extramedullary schwannoma. The purpose of this study was to compare treatment results in the differential surgery of intradural extramedullary schwannoma. A reference guide to the surgical procedures available to treat intradural extramedullary schwannoma has not yet been established. 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. Cervical vertebrae: The estimated blood loss in Group B was significantly less than in Group C (P<0.05) (Table 1). Thoracic vertebrae: The duration of hospital stay and estimated blood loss in Group A was significantly less than in Group C (P<0.05) (Table 2, 3). Lumbar vertebrae: The resection rate in Group C was significantly higher than in Group A and Group B (P<0.05) (Table 4). Treatment in Group B was the least expensive, and therefore, the most cost-effective.

In the case of appropriate surgical indications, the study suggests that hemilaminectomy+microscopic excision is advantageous in the removal of cervical schwannoma, and that laminectomy+microscopic excision is advantageous in the removal of thoracic schwannoma; lumbar intradural extramedullary schwannoma can be managed by laminectomy+microscopic excision+pedicle screw fixation. Final Decision: yes
