Filter by: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.
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 purpose of this study is to measure objectively the coupling from direct acoustic cochlear stimulation to the inner ear with a non-invasive technique of auditory evoked potentials.
