Objective: To evaluate the long-term medical and technical results, implant survival, and complications of the semi-implantable vibrant soundbridge (VSB), otologics middle ear transducer (MET), and the otologics fully implantable ossicular stimulator (FIMOS).

Study Design: Retrospective cohort study.

Patients: Patients with chronic external otitis and either moderate to severe sensorineural or conductive/mixed hearing loss.

Objective: To evaluate the transcanal surgical implantation of the semi-implantable Vibrant Soundbridge (VSB) device in patients with severe external otitis.

Study Design: Retrospective analysis.

Methods: Long-term postoperative complications and postoperative hearing thresholds were evaluated in 13 adults with bilateral sensorineural hearing loss (average of between 40 and 55 dB HL) and therapy-resistant external otitis after implantation of the VSB by a transcanal surgical method.

Objective: To determine the inter-observer reliability in localization of recorded stridor sounds in children.

Method: The stridor sounds of 28 children programmed for laryngobronchoscopy were recorded with a high quality digital recorder. Nineteen of these recordings with a diagnosis confirmed by endoscopy, were presented to otorhinolaryngology residents, academic specialists and non-academic consultants (n=38) in different situations with and without additional information about the subject.
