The best approach for repairing breaks in the thin bone that separates the brain from the nasal cavity is through the nasal cavity, according to an analysis of 92 patients who had this increasingly common approach to treating a fortunately rare problem.
The intranasal endoscopic approach is the best way to treat a potentially very bad problem," says Dr. Stilianos E. Kountakis, vice chair of the Medical College of Georgia Department of Otolaryngology-Head and Neck Surgery and principal author of the study published in the October issue of The Laryngoscope. The alternative is opening the skull, moving the front portion of the brain out of the way – destroying smell nerves in the process – and approaching the defect from the top, an approach that may be necessary if the defect is too big to treat endoscopically, Dr. Kountakis says.
However, Dr. Kountakis suggests trying the endoscopic approach – which uses small cameras and monitors so surgeons can operate with minimal trauma – several times before resorting to the open procedure. The condition, called cerebrospinal fluid rhinorrhea, results when trauma or high pressures inside the skull cause a break that allows a direct communication between the nose and brain, potentially causing meningitis and even death.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
