Mediastinal dumbbell tumors can be resected with a variety of open surgical approaches. Recently, thoracoscopic techniques have been suggested for the treatment of benign neurogenic lesions. Over a 5-year period, three patients with a benign mediastinal dumbbell tumor were treated via a combined microneurosurgical and thoracoscopic approach. The neurosurgical phase consisted of a posterior laminectomy to free the tumor from the spinal cord, followed by an intervertebral foraminotomy. Thoracoscopic resection of the lesion was then performed in the same setting. The operative times were 240, 260, and 280 min, and there were no operative complications. The postoperative stays were 6, 7, and 7 days; the postoperative period was uneventful in all three patients. Pathologic examination revealed a benign schwannoma in two cases and an angiolipoma in one case. One patient reported the onset of paraesthesia in the left hypocondrium on the distribution area of the transected T10 and T11 intercostal nerves; slight paraesthesia still remains 15 months from surgery. We conclude that the combined posterior neurosurgical and thoracoscopic approach is a safe and effective method for the removal of benign mediastinal dumbbell tumors, whether neurogenic or nonneurogenic in origin.
