Objective: Osia is a new, transcutaneous, active bone-conduction implant. This study aimed to compare the BAHA Attract and the first-generation Osia system after BAHA Attract to Osia conversion surgery. Method: Five patients who had previously used the BAHA Attract system were converted to the first generation of the Osia system. Surgical aspects of the two different systems, audiological performance and subjective opinions of the patients were investigated. Pure tone audiometry and speech audiometry in quiet was performed with each patient's BAHA 5 sound processor on Attract, and the test battery was repeated six weeks after the Attract to Osia conversion and at different time points after the first fitting. Details of the surgery and patients' feedback were analysed. Results: Audiology tests showed significant improvement when using either system; however, the Osia system performance was better. Based on patient feedback, all the five implantees preferred the Osia system. Conclusion: The study results suggest that the Osia system is a safe and powerful hearing implant that provides good clinical outcomes. [ABSTRACT FROM AUTHOR]

Objectives: To review and provide evidence-based recommendations for the diagnosis and treatment of otosclerosis. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on otosclerosis were eligible for inclusion. The American College of Physicians’ guideline grading system and the American Thyroid Association’s guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: 1) Diagnosis – audiologic and radiologic; 2) Treatment – hearing AIDS, pharmacological therapy, stapes surgery, and implantable devices – bone-anchored devices, active middle ear implants, and Cochlear Implants (CI). Conclusions: The pathophysiology of otosclerosis has not yet been fully elucidated, but environmental factors and unidentified genes are likely to play a significant role in it. Women with otosclerosis are not at increased risk of worsening clinical condition due to the use of contraceptives or during pregnancy. Drug treatment has shown little benefit. If the patient does not want to undergo stapedotomy, the use of hearing aids is well indicated. Implantable systems should be indicated only in rare cases, and the CI should be indicated in cases of profound deafness.
