Article Title: Collagen Matrix Combined With Hydroxyapatite and Nasoseptal Flap for Skull Base Reconstruction

doi: 10.1002/lio2.70192

Figure Lengend Snippet: Skull base reconstruction using collagen matrix‐hydroxyapatite (HXA)‐nasoseptal flap (NSF). (A) A collagen matrix is placed as an inlay into the dura defect. (B) An acellular dermal graft is placed as an onlay. (C) Tachosil (Takeda Austria GmbH, Linz, Austria) is placed as the final component to seal the intradural compartment. (D) The bone defect was completely covered using injectable HXA. (E) The NSF was then placed over the HXA to separate it from the nasal cavity. (F) Merocel nasal packing was inserted to stabilize the flap.

Article Snippet: Injectable HXA (Hydroset, Stryker Leibinger, Freiburg, Germany) was applied to completely cover the bony defect.

Article Title: Stereotactic Neurosurgical Treatment Options for Craniopharyngioma

doi: 10.3389/fendo.2012.00063

Figure Lengend Snippet: (A–D) Eleven-year-old boy with a large craniopharyngioma cyst. Planning for a stereotactic biopsy and a cyst puncture with subsequent internal drainage showing the trajectory in an approach oriented view. Stereotactic planning system: STP4 – workstation (Stryker-Leibinger, Freiburg, Germany).

Article Snippet: Optimized planning of the stereotactic approach is accomplished on a stereotactic workstation (STP, Stryker-Leibinger, Freiburg, Germany or Precisis Plus, Inomed, Emmendingen, Germany; Figure ) based on preoperatively acquired high resolution MRI (MP-Rage post contrast and T2 – Space, 1 mm, transversal or longitudinal orientation, Avanto, Siemens, Germany,) and intraoperative computed tomography (1 or 2 mm, transversal, Somatom Plus, Siemens, Germany) following stereotactic head fixation.
