Osteoplastic laminectomy for resection of a ganglioneuroma at the sacral spine: A technical note

Abstract

Osteoplastic laminectomy is a surgical procedure that enables a wide field during the surgery and enables preservation of the posterior vertebral column structure by refixing the lamina once separated. We performed an osteoplastic laminectomy for resection of a ganglioneuroma at the sacral spine, and improved previous lower limb pain. A 33-year-old woman complained of pain in the nerve root region of the left S1. Examination revealed an epidural tumor at the left S2 level and we planned to remove the tumor. By performing an osteoplastic laminectomy at the level of S1–S3, we could secure a wide view of the surgical site and reliably resect the tumor. Pathological examination revealed that the resected tumor was a ganglioneuroma that had a possibility of malignant conversion. The postoperative course of our patient was favorable and no complaint was heard about surgical site pain postoperatively. There has been no tumor recurrence for more than 2 years. Osteoplastic laminectomy is considered to be a useful technique for epidural tumors at the sacral spine.
