Sudden Sensorineural Hearing Loss: MR Imaging

Abstract: Hearing loss greater than 30 dB over three contiguous pure-tone frequencies occurring within a three day period is defined as sudden hearing loss. It is usually sensorineural (SSNHL), unilateral an...

Das maximale Einsilberverstehen als Prädiktor für das Sprachverstehen mit Cochleaimplantat

Abstract: Ziel war die Untersuchung des Sprachverstehens von Tragern eines Cochleaimplantats (CI) mit praoperativ messbarem ipsilateralem Einsilberverstehen. Diese Ergebnisse sollen die individuelle Beratung von CI-Kandidaten unterstutzen. Es erfolgte die Analyse von pra- und postoperativen sprachaudiometrischen Grosen wie dem maximalem Einsilberverstehen (mEV) sowie dem Einsilberverstehen bei einem Umgangssprachpegel von 65 dBSPL, also bei einer ublichen Sprechlautstarke, mit Horgerat einerseits und mit CI andererseits. Hierzu wurden die Daten von 284 erfahrenen erwachsenen CI-Tragern in Abhangigkeit von ihrem praoperativen mEV gruppiert und ausgewertet. Das postoperative Einsilberverstehen ubertraf das praoperative mEV in 96 % der Falle. Im Median lag das postoperative Einsilberverstehen bei 72,5 %. Die Gruppen mit praoperativem mEV uber 0 % erreichten ein signifikant besseres Einsilberverstehen mit CI als die Gruppe mit mEV = 0 %. Die Verbesserung gegenuber dem praoperativen Einsilberverstehen mit Horgerat lag im Median bei 65 Prozentpunkten, unabhangig von der Hohe des praoperativen Sprachverstehens. Das praoperative mEV kann als untere Abschatzung fur das Sprachverstehen mit CI interpretiert werden. Insbesondere fur CI-Kandidaten mit praoperativem Sprachverstehen ist dieser Befund von hoher klinischer individueller Relevanz.

EEG frontal asymmetry related to pleasantness of music perception in healthy children and cochlear implanted users

Abstract: Interestingly, the international debate about the quality of music fruition for cochlear implanted users does not take into account the hypothesis that bilateral users could perceive music in a more pleasant way with respect to monolateral users. In this scenario, the aim of the present study was to investigate if cerebral signs of pleasantness during music perception in healthy child are similar to those observed in monolateral and in bilateral cochlear implanted users. In fact, previous observations in literature on healthy subjects have indicated that variations of the frontal EEG alpha activity are correlated with the perceived pleasantness of the sensory stimulation received (approach-withdrawal theory). In particular, here we described differences between cortical activities estimated in the alpha frequency band for a healthy child and in patients having a monolateral or a bilateral cochlear implant during the fruition of a musical cartoon. The results of the present analysis showed that the alpha EEG asymmetry patterns observed in a healthy child and that of a bilateral cochlear implanted patient are congruent with the approach-withdrawal theory. Conversely, the scalp topographic distribution of EEG power spectra in the alpha band resulting from the monolateral cochlear user presents a different EEG pattern from the normal and bilateral implanted patients. Such differences could be explained at the light of the approach-withdrawal theory. In fact, the present findings support the hypothesis that a monolateral cochlear implanted user could perceive the music in a less pleasant way when compared to a healthy subject or to a bilateral cochlear user.

Bone conduction magnetic retention system

Abstract: An external component of a medical device, including an actuator including a static magnetic flux path that reacts with a dynamic magnetic flux path to actuate the actuator, and a magnetic retention system configured to retain the external component to a recipient via interaction with a ferromagnetic component attached to a recipient, the magnetic retention system including a magnetic flux path that encircles the static magnetic flux path of the actuator

Sphincteric control system

Abstract: A sphincteric control system for controlling the function of a bodily organ, such as the bladder. The system includes a first implanted sphincter disposed about a portion of the bodily organ, a second implanted sphincter disposed about a portion of the bodily organ, and a stimulator unit that is adapted to apply electrical stimulation to each of the first and second implanted sphincters. One of the first or second implanted sphincters is made from a smooth muscle and the other of the first or second implanted sphincters is made from a striated muscle.
