Conventional methods of stabilizing fragments in cranial impression fracture include the use of threads, wires, plates, etc. A new approach to facilitate this surgery is the use of titanium clamps, presented here in five cases, including one with frontal sinus fracture. Surgery was performed on admission day, with the exception of the sinus fracture. Compared with the use of mini- and microplates, the procedure was simple and short. The fixation was very rigid and the esthetic result excellent in all five cases. Skin irritation was minimal, compared with that from miniplates. Computed tomography and MRI compatibility due to artifacts are identical to those with miniplates.

Transcranial Direct Current Stimulation (tDCS) is a non-invasive procedure where a weak electrical current is applied across the scalp to modulate brain function. The proliferation of this therapy has been accompanied by isolated reports regarding concern about their safety namely skin irritation. The potential cause of skin irritation has sometimes been attributed to increased scalp temperature during stimulation. We have developed novel technology for tDCS that improves spatial focality at the cost of increased stimulation electrode current density; high density tDCS (HD-tDCS). The goal of this paper was to provide information on the thermal effects of tDCS using a MRI-derived finite element human head model. The tissue temperature increases of tDCS using conventional rectangular-pad (7 x 5 cm(2)) and HD-tDCS using the ring (4 x 1) electrode configurations were compared using a bio-heat model. Our results indicate that clinical tDCS do not increase tissue temperature and 4 x 1 ring configurations leads to a negligible increase in scalp temperature.
