After surgery for mediastinal schwannoma, decreased quality of life(QOL) is noted in patients if nerve disorders associated with neurectomy develop. The authors successfully performed thoracoscopic intra-capsular enucleation for mediastinal schwannoma in five patients, three men and two women with a mean age of 44.4 years. All the patients were diagnosed with shwannoma based on the results of preoperative chest computed tomography(CT) and magnetic resonance imaging(MRI), and they underwent surgery. First, the capsule of the tumor was incised to expose the tumor. After blunt detachment of the tumor and the capsule was performed without using electric knife when possible to avoid electrical and thermal damage to the nerves, the tumor was completely removed without any nerve disorder. Thoracoscopic intra-capsular enucleation can lead to problems such as massive hemorrhage from the capsule after tumor removal. However, as it is a less-invasive surgery, it is expected to preserve nerve function.
