Abstract

The aim of this study was to investigate the surgical methods and efficacies for cervicothoracolumbar spinal schwannoma (CSS). A total of 52 patients who had undergone treatment for schwannoma were retrospectively analyzed. Two methods were employed for the surgical resection of the thoracic and lumbar schwannomas: Type I (posterior midline approach semi‑laminectomy with tumor resection and internal fixation with pedicle screws) was used in 24 cases, and type II (posterior midline approach laminectomy with tumor resection and internal fixation with pedicle screws) was used in 26 cases. Two cases of giant cervical schwannoma were treated via anterior‑posterior combined surgery. Histopathological examination confirmed the diagnosis of schwannoma in all cases (n=52). The clinical status of the patients was evaluated pre‑ and postoperatively using the visual analog scale, Oswestry Disability Index and Japanese Orthopedic Association scale, and the scores associated with the two types of surgical method were compared. Within the follow‑up period, which lasted between 6 months and 3 years, no recurrence was detected, and such preoperative symptoms as radicular pain and spinal dysfunction were improved significantly. The numbness and hyperesthesia were relieved to different extents. In conclusion, methods of exposing and surgically treating CSS should be selected according to the growth site of the schwannoma in order to reduce the blood loss and surgery duration and to improve the surgical safety.
