Multi-Center Study on Performance of the Ponto Implant System Using Minimally Invasive Ponto Surgery (in Adult Patients)

This prospective, multi-centre study funded by Oticon Medical AB will be conducted at six clinical sites in North America. Patients with a hearing loss and that are already planned for treatment with a percutaneous (through the skin) bone-anchored hearing system (BAHS) will be included in the study. The total number of participants included in the study will be 64. Patients who are withdrawn from the study prior to completion will not be replaced. The purpose of this study is to investigate the rate of successful BAHS use after implantation of the Ponto Implant system using the surgical technique Minimally Invasive Ponto Surgery (MIPS). The implant, coupled to a skin-penetrating abutment, is implanted in the bone behind the ear and is later loaded with a sound processor which transforms sound waves to sound vibrations that can be sent directly to the inner ear via the skull bone. The primary objective of this study is to investigate the proportion of implant/abutment complexes providing a reliable anchorage for a sound processor, 3 months after implantation/surgery.
