Transmuscular trocar technique - minimal access spine surgery for far lateral lumbar disc herniations.
Minimal access spine surgery (MASS) is gaining increasing importance in microsurgery of the lumbar spine. From a current prospective series we present data on MASS for far lateral lumbar disc herniations (LLDH) via a transmuscular trocar technique (T(2)). The surgical procedure and operative results are demonstrated in detail. In contrast to conventional percutaneous endoscopic techniques, T(2) allows one to operate in the typical microsurgical fashion combined with the advantages of a minimal endoscopic approach with three-dimensional visualization of the surgical target using the operating microscope. ⋯ The T(2) technique represents an auspicious alternative to standard open microsurgery for LLDH, which allows achievement of excellent clinical and cosmetic results, preservation of segmental spine stability, and avoidance of excessive soft tissue trauma.

A simple technique for bridging small cranial dural defects without the use of grafts: technical note.
A watertight closure of the dura is important in preventing post-operative complications. Various techniques are described to close small dura defects. We present a simple technique that uses on site homologues dura tissue to bridge small dura defects by separating the periosteum from the inner meningeal layer. This provides a low-cost, tension-free repair without the use of synthetic materials or need to harvest autologous materials.

Case ReportsUse of 3DFT-CISS sequences and virtual MR endoscopy for the neuroendoscopic treatment of unilateral hydrocephalus: case illustration.
Intraventricular virtual MR endoscopic imaging of the foramen of Monro region by using three-dimensional Fourier transformation constructive interference in steady state (3DFT-CISS) magnetic resonance imaging in a patient with a unilateral congenital obstruction of the foramen of Monro by a transparent membranous septum was performed to enhance the orientation, achieve a better understanding of the pathology, and plan the surgical intervention in an endoscopic approach to the lateral ventricles. ⋯ Virtual MR endoscopy by using 3DFT-CISS sequences is a feasible method in the planning of intraventricular real-time endoscopic surgery, for the enhancement of orientation in a surgical field, and to achieve a better understanding of the pathology.

A new full-endoscopic technique for cervical posterior foraminotomy in the treatment of lateral disc herniations using 6.9-mm endoscopes: prospective 2-year results of 87 patients.
Anterior cervical decompression and fusion (ACDF) is the standard procedure for operation of cervical disc herniations with radicular arm pain. Mobility-preserving posterior foraminotomy is the most common alternative in the case of a lateral localization of the pathology. Despite good clinical results, problems may arise due to traumatization of the access. ⋯ No serious surgical complications occurred. The recorded results show that the full-endoscopic posterior foraminotomy is a sufficient and safe supplement and alternative to conventional procedures when the indication criteria are fulfilled. At the same time, it offers the advantages of a minimally invasive intervention.

Delayed endoscopic intraventricular hemorrhage (IVH) removal and endoscopic third ventriculostomy may not prevent consecutive communicating hydrocephalus if IVH removal was insufficient.
The aim of this study was to investigate whether delayed endoscopic treatment of intraventricular hemorrhage (IVH) can prevent consecutive communicating hydrocephalus. ⋯ Delayed endoscopic IVH removal and ETV might not prevent consecutive communicating hydrocephalus if IVH removal was insufficient.
