Summary
Osseointegrated auditory devices (OADs) enhance hearing by stimulating bone conduction through a titanium implant. These advanced hearing solutions have evolved significantly since 1977, improving technology and expanding patient eligibility.
Area of Science:
- Audiology and Biomedical Engineering
- Cochlear Implants and Hearing Restoration
Background:
- Osseointegrated auditory devices (OADs) offer an alternative for hearing loss.
- They function via bone conduction, bypassing damaged outer or middle ear structures.
Observation:
- OADs utilize an external processor stimulating a titanium implant osseointegrated with the cranium.
- Sound is transmitted directly to the inner ear through bone conduction.
Findings:
- Since 1977, OADs have seen major advancements in implant manufacturing and external processor technology.
- Surgical implantation techniques have been simplified over time.
- Patient candidacy criteria have expanded due to technological progress.
Implications:
- These advancements in OADs improve treatment options for hearing loss.
- Evolving technology broadens the potential patient population for osseointegrated hearing solutions.

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.

01:25The Anchoring-and-Adjustment Heuristic
7.8K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

01:03Anchoring Junctions
5.0K
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...

01:32Lipids as Anchors
7.3K
In the plasma membrane, the lipids forming the bilayer can also act as an anchor to tether proteins to the membrane. The three main types of lipid anchors found in eukaryotes are – prenyl groups, fatty acyl groups, and glycosylphosphatidylinositol or GPI groups. Prenyl and fatty acyl groups act as anchors on the cytosolic surface of the membrane, whereas GPI anchors proteins on the extracellular side.

01:11The Auditory Ossicles
3.1K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

GPI-anchoring is a post-translational, reversible protein modification that is ubiquitous in eukaryotes. Such proteins are primarily present on the exoplasmic leaflet of the plasma membrane.
GPI-anchor structure
A sequence of 11 enzymatic reactions results in the synthesis of the complete GPI anchor consisting of a hydrophobic and a hydrophilic portion. The hydrophobic portion comprises phosphatidylinositol, while the hydrophilic part comprises polar groups like phosphoethanolamine,...
