What is a sensorineural hearing loss?
Sensorineural hearing loss is the form of permanent hearing loss, which is based on problems in the inner ear, vestibulococlear nerve or brain. There are several conditions that can contribute to the development of this progressive, irreversible forms of hearing loss. Treatment of sensorineural hearing loss involves the use of either auditory devices or cochlear implants. In some cases, the hearing may be permanently lost due to the problems inside the inner ear itself, such as congenital defect, birth injury or infection. Sensorineural hearing loss can also result from damage to vestibulocochlear nerve or impaired sensory processing in the brain.
nervous deafness is usually considered, despite the absence of the only one that there are several suspicious factors that can contribute to the progression of hearing loss. Individuals who acquire viral infection such as rubel or herpes simplex can develop complications that lead to the development of nervous deafness. Among other conditions that canOU contribute to irreversible hearing loss, include leukemia, scarlet fever and autoimmune diseases such as lupus. Individuals who maintain trauma on their inner ear or vestibulocochlear nerve, such as injuries resulting from a fracture of the skull or perforation of the ear drum, can be diagnosed with nervous deafness.
Symptoms associated with sensorineural hearing loss are dependent on the age of the individual and the extent of hearing loss after diagnosis. Infants with hearing loss may show behavioral symptoms such as lack of reaction to hearing impulses or the absence of vocalization. Children with nervous deafness mneb will be able to hear higher playgrounds or sounds that some letters make, such as "with" or "Z." Other symptoms of sensorineural hearing loss include vertigo and persistent ringing or buzzing in the ears known as tinnitus.
Diagnosis of nervous deafness can be confirmed by the ÚPLin medical history and ears examination. In some cases, the display testing may be performed, including computer tomography (CT) and magnetic resonance (MRI) scanning. Hearing tests can also be administered for better evaluation of the degree of hearing loss.
Treatment of sensorineural hearing loss may include the use of auditory devices that fit just inside the ear. Most hearing devices, also known as hearing aids, are designed to be almost cosmetically invisible. The device is equipped with a small microphone used to amplify the sounds and transmit them to the ear. The auditory device can be independently controlled to suit the individual purpose and needs.
cochlear implants are a prosthetic substitute for hearing and are not considered to be a medicine for hearing loss. As a help for hearing and speech, the implant allows the audience to represent sounds in his environment. In contrast to the auditory device, the cochlear implant is working by hearing stimulationa nerve.
The complex in its composition The cochlear implant consists of a microphone, speech processor, transmitter, stimulator and receiver. The inner parts of the implant consist of a stimulator and receiver, which are located in the cochle and just below the skin behind the ear. The outer part of the device consists of a speech processor, a microphone and transmitter and is located behind the ear directly above the implanted receiver.
After surgery, the individual can initiate speech therapy and work closely with an audiologist and speech therapist. Prognosis associated with cochlear implant phenomenon of dependence on several factors, including the success of surgery and how long the individual had been a deaf or auditory before surgery. Learning to interpret the sounds they hear and be able to process this information are necessary to derive the most benefits from the implant.
