OBJECTIVE To evaluate the outcomes of younger (<60 yr) and older (≥60 yr) patients implanted with the Vibrant Soundbridge (VSB). The aim was to determine if there were differences between groups. METHOD A retrospective study was used to evaluate all patients who were implanted and fit with a VSB during 2008 and 2009 at the Department of(More)
Active middle ear implants, such as the Vibrant Soundbridge, are used as an important part in the rehabilitation of sensorineural, conductive hearing, or mixed hearing loss. The attachment of the Vibrant Soundbridge at the round window and the usage of the Vibroplasty couplers strongly expanded the application of the Vibrant Soundbridge.The Vibrant(More)
Helmet use on ski slopes has steadily increased worldwide over the past years. A common reason reported for helmet non-use, however, is impaired hearing. Therefore, an intra-subject design study was conducted to compare hearing thresholds and sound source localization of 21 adults with normal hearing in an anechoic chamber when wearing a ski helmet and ski(More)
CONCLUSIONS Patients, who are bilaterally supplied with active middle ear implants, perform slightly better in sound localization tasks than when unilaterally aided or unaided. OBJECTIVES To investigate the impact of bilateral use of active middle ear implants on sound source localization in the horizontal plane in patients with a sloping(More)
Binaural sound reception has advantages over unilateral perception, including better localization and sound quality as well as speech and tone reception in both quiet and noisy environments. Up to now, most active middle ear implant (AMEI) users have been unilaterally implanted, but patient demand for an implant on the other side is increasing. Ten(More)
OBJECTIVE To investigate the safety and efficacy of a new bone conduction hearing implant in children, during a 3-month follow-up period. STUDY DESIGN Prospective, single-subject repeated-measures design in which each subject serves as his/her own control. SETTING Otolaryngology departments of four Austrian hospitals. PATIENTS Twelve German-speaking(More)
Excretion of attenuated polioviruses after controlled type 3 poliovaccine administration was studied in the district city of Cheb. The usual type 3 dose, 10(5) TCD50, was doubled in some vaccinees. A total of 972 stool samples collected from primary vaccinees and their family members were examined; three samplings were carried out in most of the subjects.(More)
