AIM Multilayer reconstruction of skull base using nasal pedicled mucosal flap has been widely accepted as a standard method for repairing high flow cerebrospinal fluid [CSF] leakage. In this study, we analyzed our outcome and summarized several valuable operation experiences from this technique. MATERIAL AND METHODS This study included 20 consecutive patients who underwent endoscopic endonasa...

PURPOSE To assess implant leakage under static conditions as well as during and after dynamic loading. Materials and methods : Implants (Astra Tech (A), Biomet 3i (B) and Nobel Biocare (C)) were evaluated for leakage (n=8/group). Testing to assess the gas pressure change over time (hPa/min) and infiltrated fluid volume, was performed in a Gas Enhanced Permeation Test (GEPT) to qualify embedding...
