Summary
Bone-conductive implants (BCI) offer reliable hearing rehabilitation for various hearing losses. Middle ear pathology and surgical outcomes are primary drivers for BCI use, with device transitions being predictable when explantation is needed.
Area of Science:
- Otorhinolaryngology
- Biomedical Engineering
- Audiology
Background:
- Bone-conductive implants (BCI) provide a viable auditory rehabilitation option for conductive, mixed hearing loss, and single-sided deafness (SSD).
- Analyzing factors influencing BCI selection is crucial for effective auditory rehabilitation strategies.
Purpose of the Study:
- To investigate the factors influencing the selection and outcomes of bone-conductive implant (BCI) use.
- To evaluate reasons for BCI explantation and subsequent hearing rehabilitation transitions.
Main Methods:
- Retrospective analysis of clinical charts from 2005 to 2018.
- Included patients who underwent BCI application at a single implanting center.
- Examined reasons for explantation and alternative rehabilitation methods.
Main Results:
- A variety of BCI devices were utilized across diverse patient cohorts, including otitis media, cholesteatoma, otosclerosis, congenital malformations, and sudden deafness.
- Middle ear pathology and post-surgical sequelae were the most frequent indications for BCI implantation in both unilateral and bilateral cases.
- Explantation was required in five subjects, necessitating a transition to alternative rehabilitation options.
Conclusions:
- Middle ear pathology and surgical consequences are the predominant reasons for BCI implantation.
- Transitioning between implantable hearing devices can be anticipated, particularly when explantation becomes necessary.
- BCI plays a significant role in rehabilitating hearing loss associated with middle ear pathologies.

02:58Properties of Transition Metals
29.7K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

02:31Phase Transitions
22.9K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

01:58Cooperative Allosteric Transitions
8.7K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

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...

02:39Phase Transitions: Vaporization and Condensation
20.8K
The physical form of a substance changes on changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. Vaporization occurs when the thermal motion of the molecules overcome the intermolecular forces, and the molecules (at the surface) escape into the gaseous state. When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules...

02:33Phase Transitions: Sublimation and Deposition
19.9K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...
