Abstract

Chondrosarcomas are slow-growing tumors with low grade malignancy and unclear histopathogenesis. Surgical excision is the treatment of choice. Combined treatment is usually recommended for high-grade lesions and residual lesions. The oncologic outcome depends on complete resection as well as on the grade of tumor. We experienced 3 cases of the chondrosarcoma of skull base. They were treated by different approaches, which were temporal/infratemporal approach, cervical/mastoid approach and transnasal endoscopic approach. In the first two cases, tumor invaded cranial dura mater. After complete excision with postoperative radiotherapy, tumor had local recurrence. In the third case, tumor invaded sellar region but only palliative surgical excision was done considering the complications of radiotherapy.
