Expert opinion on candidacy for bone conduction hearing implants Osia System and Baha Connect System

Area of Science:

• Otolaryngology
• Audiology
• Biomedical Engineering

Background:

• Bone conduction hearing implants (BCHI) are vital for treating conductive hearing loss (CHL), mixed hearing loss (MHL), and single-sided deafness (SSD).
• Selecting the appropriate BCHI system, such as active transcutaneous (Osia) or passive percutaneous (Baha Connect), is crucial for successful patient outcomes.
• Clinical decision-making is often influenced by economic factors, patient preferences, and specific medical considerations.

Purpose of the Study:

• To present expert-driven candidacy criteria for choosing between the Osia System and Baha Connect System.
• To streamline the decision-making process for bone conduction hearing implants, especially when cost is a significant factor.
• To highlight key considerations for professionals and patients when selecting an optimal BCHI solution.

Main Methods:

• An expert review involving eight specialists in audiology and otolaryngology.
• Two online surveys and two virtual meetings were conducted to gather real-world clinical insights.
• Consensus was reached on key decision-making factors for BCHI selection.

Main Results:

• Candidacy factors include anesthesia requirements (local vs. general), bone thickness, and future Magnetic Resonance Imaging (MRI) needs.
• The Baha Connect System may be less suitable for patients with concerns about skin infections, site management, or limited dexterity.
• The Osia System may offer advantages for patients prioritizing hearing performance, while Baha Connect suits those needing minimally invasive surgery or frequent MRIs.

Conclusions:

• The choice between Osia and Baha Connect depends on a multidisciplinary discussion of individual patient needs and preferences.
• Anesthesia type, MRI compatibility, and implant site care are critical considerations.
• Osia may be preferred for superior hearing outcomes, whereas Baha Connect offers benefits for minimally invasive procedures and MRI accessibility.
