Mixed hearing loss combines conductive and sensorineural components, necessitating a multifaceted treatment approach. Each type presents unique challenges and highlights the need for targeted therapies that stem cell research aims to address.
The auditory system constitutes a complex network that converts sound waves into electrical signals, which the brain interprets as sound. This intricate process begins in the outer ear, where sound waves are directed through the ear canal and strike the eardrum. The resulting vibrations then travel through the ossicles in the middle ear, amplifying and transmitting them to the cochlea in the inner ear.
Within the cochlea, specialized hair cells detect these vibrations and convert them into electrical signals. These signals traverse along the auditory nerve to the brain, where they are processed and perceived as sound. A multitude of factors can disrupt this process, leading to hearing impairment. Stem cell therapy aims to intervene at these critical junctures, potentially restoring function by regenerating damaged auditory cells or reinstating disrupted signalling pathways.
Hearing impairment can arise from numerous causes, necessitating diverse treatment strategies.
