Preliminary Investigations for Non-invasive Temperature Change Detection in Thermotherapy by Means of UWB Microwave Radar.

Non-invasive differential temperature monitoring by means of ultra-wideband sensing is a promising approach concerning temperature controlling during thermotherapy. In this paper the principal of temperature difference detection by UWB radar is explained and appropriate phantom measurements are discussed. In a first step, temperature dependent dielectric properties of the phantom materials (sunflower oil and distilled water) are analyzed.

Open-Ended Coaxial Probe Technique for Dielectric Measurement of Biological Tissues: Challenges and Common Practices.

Electromagnetic (EM) medical technologies are rapidly expanding worldwide for both diagnostics and therapeutics. As these technologies are low-cost and minimally invasive, they have been the focus of significant research efforts in recent years. Such technologies are often based on the assumption that there is a contrast in the dielectric properties of different tissue types or that the properties of particular tissues fall within a defined range.

Does attempt at hearing preservation microsurgery of vestibular schwannoma affect postoperative tinnitus?

Background: The aim of this study was to analyze the effect of vestibular schwannoma microsurgery via the retrosigmoid-transmeatal approach with special reference to the postoperative tinnitus outcome.

Material And Methods: A prospective study was performed in 89 consecutive patients with unilateral vestibular schwannoma indicated for microsurgery. Patient and tumor related parameters, pre- and postoperative hearing level, intraoperative findings, and hearing and tinnitus handicap inventory scores were analyzed.

Minimally invasive video-assisted versus minimally invasive nonendoscopic thyroidectomy.

Minimally invasive video-assisted thyroidectomy (MIVAT) and minimally invasive nonendoscopic thyroidectomy (MINET) represent well accepted and reproducible techniques developed with the main goal to improve cosmetic outcome, accelerate healing, and increase patient's comfort following thyroid surgery. Between 2007 and 2011, a prospective nonrandomized study of patients undergoing minimally invasive thyroid surgery was performed to compare advantages and disadvantages of the two different techniques. There were no significant differences in the length of incision to perform surgical procedures.
