Comparative StudyProspective comparative study of lumbar sequestrectomy and microdiscectomy.
During microsurgical disc operation, usually a sequestrectomy and a nucleotomy are performed. Whether a nucleotomy is necessary in any case is disputed. The aim of this study is to examine this question on the basis of clinical results and to compare rates of recurrence between the two groups. ⋯ Sequestrectomy alone is a safe operative modality. Sequestrectomy does not seem to entail a higher rate of recurrences compared with microdiscectomy and the results are as favourable as or better than results after discectomy.

The minimally invasive supraorbital subfrontal key-hole approach for surgical treatment of temporomesial lesions of the dominant hemisphere.
Surgery in the temporomesial region is generally performed using a subtemporal, transtemporal, or pterional-transsylvian approach. However, these approaches may lead to approach-related trauma of the temporal lobe and frontotemporal operculum with subsequent postoperative neurological deficits. Iatrogenic traumatisation is especially significant if surgery is performed in the dominant hemisphere. ⋯ In selected cases, the minimally invasive supraorbital craniotomy offers excellent surgical efficiency in the temporomesial region with no approach-related morbidity compared to a standard transtemporal or pterional-transsylvian approach.

Case ReportsNeuronavigation in the minimally invasive presacral approach for lumbosacral fusion.
Intraoperative 3D navigation (3D NAV) is gaining importance in spinal surgery, especially with the advancement of minimally invasive techniques in this field. We hypothesized that 3D NAV may be of benefit in the recently described minimally invasive presacral approach for L4-S1 fusion (AxiaLIF). ⋯ The minimally invasive presacral approach to L4-L5-S1 fusion can be performed safely and accurately with intraoperative 3D NAV. This is especially the case in two-level AxiaLIF procedures, where computer guidance can provide better planning possibilities for optimal screw trajectory.

Minimally invasive awake craniotomy using Steiner-Lindquist stereotactic laser guidance.
Awake craniotomy permits the continuous assessment of intraoperative neurological functions. In addition, stereotactic laser guidance aids in performing minimally invasive procedures related to the radical resection of lesions located in eloquent and non-eloquent brain regions. ⋯ Awake craniotomy with the aid of stereotactic laser guidance is a safe procedure that assists in performing minimally invasive resection of lesions in eloquent and non-eloquent brain regions. Although direct intraoperative stimulation was not performed, detection of the functioning areas of the brain with fMRI decreased additional postoperative neurological deficits. Overall, this method decreased the operation time and hospital stay.

Technique for shaping microcatheter tips in coil embolization of paraclinoid aneurysms using full-scale volume rendering images of 3D rotational angiography.
In coil embolization of paraclinoid aneurysms, it is sometimes difficult to introduce and stabilize microcatheter tips in the aneurysms. We report a new technique for shaping microcatheter tips in the coil embolization of paraclinoid aneurysms. ⋯ This technique is feasible for shaping microcatheter tips precisely for coil embolization of paraclinoid aneurysms.
