| Tartalmi kivonat: | The CochlearTM Osia® 2 is an active transcutaneous implant designed to treat patients with different types of hearing loss. Due to its size, implantation needs appropriate practice since the necessity of extended flap creation and bone work can be an issue in some cases. The goal of our study was to determine whether fixation of the OSI200 implant was necessary for the performance of patients with conductive or mild mixed hearing loss. The vibroacoustic performance of the Osia 2 system, with and without BI300 fixation, was evaluated through tests conducted on a head model. In addition, three patients underwent surgery using the modified minimally invasive subperiosteal pocket technique; the OSI200 implant was placed in a tight subperiosteal pocket without fixing it with the BI300 implant. To evaluate the audiological performance of the non-fixated Osia 2 system, we compared the preoperative unaided pure tone and suprathreshold testing with the Baha 5 sound processor and the non-fixated Osia 2 system aided thresholds. Initial results indicate that omitting fixation does not significantly impair the function of the Osia 2 system. The findings of the clinical assessment support the fact that the Osia 2 system performed better than the Baha 5 system on Softband, both in pure tone and suprathreshold tests. According to our results, we have found that utilizing the subperiosteal pocket method and implanting Osia 2 without BI300 fixation may be a viable option. This approach has shown promising results in terms of improving hearing ability with minimalization of surgery related complications. © The Author(s) 2024. |
