Precise knowledge of localization, size, histopathological features, and involved anatomical structures are important while pianning the approach to lesions of thoracic or lumbar regions. İn lesions affecting the vertebral body and exerting ventral compression to the spinal cord, an anterior approach is preferred, while a posterior approach is considered for treatment of lesions located in the posterior structures of the vertebrae and compressing the cord posteriorly. Combined posterior and anterior approaches to lesions compressing the cord laterally or expanding in between the natural compartments carry the disadvantages of both a prolonged time of surgery and increased morbidity rates. The extended posterior approach which is becoming popular and vvidely accepted for this kind of lesions is discussed with presentation of two cases. The first case is a patient who had an aneurysmal bone cyst extending into paraspinal structures unilaterally, and the other one is a patient with a mesenchymal sarcoma, who were both operated using a lateral extra-cavitary route to remove the lesions extending to the vertebral body and stabilized by posterior instrumentation though a posterior approach,
