Summary
Bone-conduction hearing implants (BCHIs) offer benefits for hearing loss. This review provides guidelines and evidence for BCHIs in bilateral hearing loss and single-sided deafness (SSD).
Area of Science:
- Audiology
- Otolaryngology
- Biomedical Engineering
Background:
- Growing availability of percutaneous and transcutaneous bone-conduction hearing implants (BCHIs).
- Limited evidence and varied methodologies hinder optimal device selection for patients.
- Need for updated guidelines and research synthesis for clinical practice.
Purpose of the Study:
- To provide audiological guidelines for the latest bone-conduction hearing implants (BCHIs).
- To review current clinical trial research on BCHIs.
- To address evidence for bilateral BCHI fitting and BCHI use in single-sided deafness (SSD).
Main Methods:
- Literature review of audiological guidelines and recent clinical trials.
- Analysis of evidence for bilateral BCHI fitting in conductive hearing loss.
- Evaluation of BCHI efficacy in single-sided deafness (SSD) using objective and subjective measures.
Main Results:
- Bilateral BCHI fitting improves hearing thresholds in quiet and sound localization, with limited benefit in noise.
- Subjective benefits of BCHIs in SSD are strongly supported by questionnaire studies.
- Objective evidence for BCHI benefit in SSD, particularly for sound localization and speech in noise, is limited.
Conclusions:
- Updated guidelines and evidence synthesis are crucial for BCHI selection.
- Bilateral BCHI fitting shows specific advantages and limitations.
- Further objective research is needed to confirm benefits of BCHIs in single-sided deafness (SSD).

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Gauss' law relates the electric flux through a closed surface to the net charge enclosed by that surface. Gauss's law can be applied to find the electric field and the charge enclosed in a region depending on its charge distribution.
Consider a cross-section of a thin, infinite conducting plate having a positive charge. For such a large thin plate, as the thickness of the plate tends to zero, the positive charges lie on the plate's two large faces. Without an external electric field, the...

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Autorhythmicity is a term that refers to the heart's inherent ability to generate electrical signals and instigate muscle contractions. This self-regulating conduction system within the heart consists of two key components: the pacemaker cells and specialized conducting cells.
The pacemaker cells are located in two primary nodes: the sinoatrial (SA) node and the atrioventricular (AV) node. The SA node pacemaker cells can autonomously depolarize, triggering an action potential that leads to the...

The cardiac conduction system produces and transmits electrical impulses that prompt myocardial contraction, ensuring efficient heart function. This intricate system ensures that the heart beats in a coordinated and efficient manner, beginning with the atria and then the ventricles. The conduction system optimizes cardiac output by maintaining this precise sequence, which is crucial for adequate blood circulation.

1.8K
In perfect conductors, the electric field inside is always zero due to the abundance of free electrons, which nullify any field by flowing. As a result, any residual charge resides on the surface.
In a practical conductor, an applied electric field may be sustained, causing a flow of electrons, which produce a current. The differential form of the current, the current density, is related to the electric field.
More generally, it is related to the force per unit charge, which involves the...
