To investigate the advantages, disadvantages and indications of hemilaminectomy for microsurgical resection of intraspinal tumors.
We retrospectively reviewed and analyzed the clinical data of 542 cases of intraspinal tumors microsurgically resected by hemilaminectomy during the period from January 2005 to December 2008.
The tumors were totally removed in 501 cases (92%). The average postoperative stay was 5.2 days. Postoperative follow-ups ranged from 6 months to 3 years (mean 9 months). The clinical symptoms of 495 cases (91%) improved. No tumor recurrence was reported in the totally removed cases. The stability of vertebral column was excellent and there was no spinal deformity in these patients.
With many advantages of minimal trauma, milder postoperative reaction, shorter length of recovery and better spinal stabilization, hemilaminectomy can be used for microsurgical resection of all lateralized epidural, subdural-extramedullary and some benign intramedullary tumors.
探讨半椎板切除术在显微手术切除椎管内肿瘤中的优缺点及适应证。
回顾性分析2005年1月至2008年12月期间采用半椎板切除术显微手术切除的542例椎管内肿瘤患者的临床资料。
501例（92%）肿瘤完全切除。术后平均住院时间为5.2天。术后随访6个月至3年（平均9个月）。495例（91%）患者临床症状改善。肿瘤完全切除的病例未报告复发。这些患者的脊柱稳定性良好，无脊柱畸形。
半椎板切除术具有创伤小、术后反应轻、恢复时间短和脊柱稳定性好等诸多优点，可用于显微手术切除所有侧方硬膜外、硬膜下髓外及部分良性髓内肿瘤。
