Background -Because of the rare occurrence of thoracic disc herniation and surgery needed treatment the used approaches and their efficiency are still subjects of discussions. In Hungarian practice, the most frequent explorations are costotransversectomy and laminectomy, but there are many other important methods available like thoracoscopic and posterior transdural approaches. This case report will present the benefits and the surgical procedure of posterior transdural sequesterectomy, carry out for the first time in Hungary at the Neurosurgical Department on Szeged University. Case presentation -A 50-year-old female patient with achondroplasic nanism has been operated several times since 2011. She suffered from a progressive, multi-segment affected degenerative discopathy and myelopathy. Finally in the background of the recurrent paraparesis was confirmed thoracic disc herniations at the levels of T8 and T9. The use of intraoperative electrophysiology was not feasable, because the earlier described cervical myelopathy. For this reason we used the posterior transdural approach, as the best and safest, visual control warranted technique. Conclusions -The posterior transdural approach offers an alternative option for experienced surgeons, furthermore in contrast with traditional, technically difficult to implement or special instrumentation demanding approaches this technique seems to be more efficient.
