Filter by:The objective of this study is to make a comparison between two surgical techniques used when implanting a Ponto bone anchored hearing system.
This study is designed to compare two different surfaces of bone anchored hearing aid abutments in terms of bacterial colonization, inflammatory response and skin reactions.
This study investigates the use of a new healing cap which, through altered design and choice of material, has been improved when it comes to minimizing the risk of it falling off as well as increasing patient comfort.
Objectives - To evaluate the safety of processor loading of the Cochlear BI300/BA400 implant system 1 week after implantation - To evaluate the short term soft tissue healing and the long term skin reaction, with the new Cochlear BI300/BA400 implant system using the linear incision without subcutaneous tissue reduction. - To produce reference data regarding the stability of the BI300/BA400 implant system. Study design: Prospective cohort study. Patients: 24 adults with anticipated normal skin and bone quality eligible for bone anchored implant surgery. Intervention: Loading of the sound processor one week after surgery Main outcome measures: Implant stability, soft tissue reaction, skin overgrowth, pain and numbness will be assessed. It is hypothesized that implant loading can be performed one week after surgery without any changes in implant stability, soft tissue reaction, skin overgrowth, pain or numbness around implant.
An international multicentre, open, comparative, parallel group, prospective clinical investigation with a single 5 year follow up visit.
A bone anchored hearing system is used to improve hearing for patients with e.g. conductive/mixed hearing loss or single sided deafness. With this type of system, a titanium implant is installed in the temporal bone, where it osseointegrates, i.e. integrates with the bone. An abutment (also in titanium) is attached to the implants and penetrates the skin. The sound processor (hearing aid) is then connected to the abutment, and can be attached and removed by the patient via a snap-coupling. This type of system has been successfully implanted in more than 100.000 patients. Recently, a simplified surgical procedure, where no skin thinning around the abutment is made, was approved. The results after using this installation technique, here called soft tissue preservation, are the focus of this study. The objective of the study is to compare the outcomes after a surgical procedure with soft tissue preservation (test) and a surgery with soft tissue reduction (control) for placing Oticon Medical Ponto implants and abutments. The main hypothesis is that patient numbness around the implant is less in the test group compared to the control group.
The rationale behind this post-market clinical follow-up investigation is to collect data regarding the usability and clinical performance of the Baha Attract System in subjects with hearing impairment that are candidates for Baha surgery: - to evaluate the efficacy of the Baha Attract System in terms of hearing performance compared to the unaided situation and compared to a pre-operative test situation using the sound processor on a Baha Softband; - to evaluate the mid- and long-term safety of the Baha Attract System.
The accurate assessment of auditory status is critical for planning treatment for Veterans with hearing loss to include medical and audiological management. Current physiologic tests of auditory function in the standard clinical audiological test battery for Veterans have limited sensitivity in detecting some middle-ear disorders, and do not include a direct test of cochlear function. Recent studies have shown promise for new wide-bandwidth (WB) tests of absorbance for improved sensitivity in the assessment of middle-ear function including acoustic reflex testing. The addition of WB tests of cochlear function included in the WB test battery provides an opportunity to improve audiological diagnosis of a range of hearing disorders in Veterans. The automation provided by the WB test battery could provide additional benefits in reducing the duration of the evaluation, leaving more time for evaluation of test findings and counseling. Results from this study may lead to the improvement of audiological care for Veterans with hearing loss.
The Bonebridge is a new bone conducting implantable hearing aid. The investigators plan to randomize patients to receive either the Bonebridge or a conventional bone conducting hearing device. The investigators will then compare the surgical and audiological outcomes of the two groups.
The rationale behind this clinical performance investigation is to collect data regarding the usability of the Baha Attract System in patients with hearing impairment that are candidates for Baha surgery: - To describe the expected hearing performance with the Baha Attract in comparison to unaided hearing thresholds or a pre-test situation using a sound processor together with a softband - Which sound processor to select, i.e. BP100 vs BP110 - Improve the fitting process for the sound processor - Selection of sound processor magnet at time of fitting and over time
