AI Article Synopsis
- A study was conducted to evaluate the use of mixed reality (MR) technology, specifically the HoloLens, for assisting in Baha Attract implant surgeries by visualizing essential structures for better precision.
- The research involved a cadaveric case study where surgeons successfully performed bilateral Baha Attract implants, and the accuracy of the MR guidance was assessed using target registration error (TRE) measurements.
- The results indicated that the MR system improved the accuracy of implant placement, showing a median TRE of 2.97 mm and suggesting potential benefits in surgical confidence, safety, efficiency, and precision.
Article Abstract
Objective: To test the feasibility of image-guided Baha Attract implant surgery with mixed reality (MR) in the form of the HoloLens to visualize critical structures and facilitate precise Baha implant placement.
Methods: A cadaveric case study of bilateral Baha Attract implant approaches was conducted using Star Atlas MR three-dimensional (3D) medical interaction system guidance at the Otolaryngology Department of PUMCH, Beijing, China. The accuracy of visual surface registration was determined by the target registration error (TRE) between the predefined points on the preoperative 3D holographic Baha Attract implant model and the postoperatively reconstructed 3D model.
Results: Bilateral Baha Attract implantation was completed successfully for all four cadaveric heads using the Star Atlas MR 3D medical interaction system with the HoloLens. The preoperative 3D digital model characteristics (including bone quality and thickness and avoidance of cranial vessels, air cells, and cranial sutures) corresponded well with the 3D model of the actual implantation reconstructed postoperatively. The median TRE of our system was 2.97 mm (ranging from 1.98 to 4.58 mm) in terms of distance and 2.76 degrees (ranging from 0.59 to 6.4 degrees) in terms of angle.
Conclusions: Applying MR technology in the form of the HoloLens in Baha Attract implant surgery is feasible and could improve the accuracy of the surgery. The described MR system for Baha Attract implantation has the potential to improve the surgeon's confidence, as well as the surgical safety, efficiency, and precision.

Objectives: Implantable bone conduction hearing devices offer excellent auditory rehabilitation. Transcutaneous devices, which use an implanted magnet, are gaining popularity due to higher skin complications associated with traditional percutaneous devices. The Cochlear Baha® Attract System (Cochlear Corporation, Sydney, Australia) is a transcutaneous device and is regarded as a passive transcutaneous implant.

Article Synopsis
- Bone Anchored Hearing Aids (BAHAs) are effective for treating hearing issues, particularly in patients with single sided deafness (SSD), and this study evaluates the BAHA Attract system's outcomes.
- A prospective observational study involving 15 patients over two years analyzed surgical success, functional improvements, audiological results, and cosmetic outcomes.
- Results showed a mean surgical time of 39 minutes, with 73% of patients healing well, significant enhancements in hearing abilities (especially sound localization), and strong cosmetic acceptance, marking the BAHA Attract as a safe option for SSD.

Article Synopsis
- Hearing loss impacts communication and quality of life, and the bone-anchored hearing aid (BAHA) helps by directly stimulating the cochlea through bone conduction.
- This study compared the effectiveness of two types of BAHA (transcutaneous and percutaneous) in improving hearing performance and subjective auditory abilities among 29 users over 6 months.
- Results showed both BAHA types led to significant improvements in speech recognition and overall hearing satisfaction without notable differences between them, confirming BAHA's effectiveness in hearing rehabilitation, particularly for those with conductive hearing loss.

Objective: This prospective study assessed the efficacy of the Cochlear™ Osia 2 System compared to the previous Baha Attract System in patients with mixed or conductive hearing loss (MHL/CHL).
Methods: In this prospective case-control study, 10 patients (2 men and 8 women) with MHL/CHL were implanted with the Osia 2 System. Their audiological outcomes were compared with 13 patients (2 men and 11 women) who had previously been implanted with the transcutaneous Baha Attract system.
