Summary
New cartilage conduction (CC) hearing aids significantly improve hearing thresholds for severe conduction hearing loss. Most patients preferred CC aids over traditional devices, indicating their practical benefit.
Area of Science:
- Otolaryngology
- Audiology
- Biomedical Engineering
Background:
- Severe conduction hearing loss, particularly from aural atresia, presents significant audiological challenges.
- Traditional hearing aids may not be suitable for all patients with these conditions.
Purpose of the Study:
- To assess the benefits and practical utility of novel cartilage conduction (CC) hearing aids.
- To evaluate CC hearing aids as a potential solution for severe conduction hearing loss.
Main Methods:
- A prospective case series involving 41 subjects with severe conduction hearing loss.
- Fitting and gain adjustments of CC hearing aids were performed.
- Speech performance, recognition, noise tolerance, and subjective feedback were evaluated.
Main Results:
- CC hearing aids significantly improved hearing thresholds.
- Functional gains were comparable to previously used hearing aids.
- 39 out of 41 subjects continued using CC hearing aids post-trial, with no severe adverse effects.
Conclusions:
- Cartilage conduction hearing aids offer a beneficial additional option for managing severe conduction hearing loss.
- CC hearing aids demonstrate practical viability and patient acceptance for conditions like aural atresia.

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.

01:16Anatomy of the Ear
12.0K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

01:13The Cochlea
51.4K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

01:15Auditory Pathway
7.6K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

01:11The Auditory Ossicles

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...

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.
