Most of these tumors are neurogenic and include schwannomas, neurofibromas, ganglioneuromas and neuroblastomas. 1.Fortunately, more than 90% of these tumors are benign.2. Dumbbell tumors of the thoracic spine are particularly difficult to expose and remove by virtue of their location and relationship with vital structures of the thoracic cavity. The traditional surgical approach for removing these tumors has been using either combined anterior thoracotomy and posterior neurosurgical procedures or the lateral extracavitary approach. We present our experience with resection of three dumbbell tumors with a combined microneurosurgical and thoracoscopic procedures in a single stage.展开更多
