Sensorineural Hearing Loss
Sensorineural Hearing Loss Symptom
Sensorineural hearing loss is a hearing loss which originates in the internal part of the ear. It may take place due to genetic as well as physical factors. Even though a treatment of loss of hearing is still a dream yet to be realized,ther are now electronic strategies specially formulated to make lives better for those distressed from this disorder.
This article delves into the various causes, symptoms and treatments of sensorineural hearing loss to present the readers with constructive facts on the subject matter.
The level of hearing impairment may show a mild loss of sensitivity in some persons to entire deafness.
In sensorineural hearing loss, the predicament lies both in the inner ear or the auditory nerves. It affects the course connecting the inner ear and the brain, to which the brain is not capable to recognize definite sounds.
The factors that causes sensorineural hearing loss are mentioned as follows:
• Aging may spoil the nerve endings of the hair cells in the cochlea due to which elderly people may bear from sensorineural hearing loss.
• Meniere’s disease and tinnitus also show the way to this disorder.
• Measles, meningitis, mumps and some other infections may cause harm to one’s audible range
• Acoustic neuroma, a non cancerous lump which affects the auditory nerves may be the source of deafness.
• The hair cells also become dysfunctional issue due to exposure to earsplitting sounds.
• A high measured quantity of certain prescriptions such as aspirin may cause sensorineural hearing loss and Tinnitus.
• Chemotherapy is also to blame in causing permanent hearing loss.
•So as Cholesteatoma in the middle ear and vertigo.
Causes and Risk Factors of Sensorineural Hearing Loss
Even though sensorineural hearing loss is an idiopathic (no known cause) condition, researchers accept as true that other factors besides age (as in presbycusis), hereditary (as in hearing loss at birth and later in life) and environmental and physical factors (as in trauma-induced problems, tumors, noise injury and drug-induced hearing loss) may play a role in hearing loss. These factors include:
- Viral infections such as influenza, rubeola, rubella, mumps, herpes simplex and CMV.
- Vascular diseases such as leukemia and sickle cell anemia
- Autoimmune diseases such as lupus and temporal arteritis
- Hereditary factors such as deafness from birth.
- Environmental factors such as noise pollution
- Physical factors such as tumors and drug induced deafness.
- Viral infections like CVE ,mumps, influenza, herpes simplex etc
The signs and symptoms of sensorineural hearing loss also include the following:
• Infants suffering from this complaint may not act in response to sound and do not make the typical baby sounds.
• Sounds cannot be heard
• Tinnitus with vertigo is a subsidiary of sensorineural hearing loss.
• Towering tones and the sounds of s, z and f are not audible
- Speech may be difficult to understand if there is background noise
The handling of this disorder includes a detailed ear check up and a few tests. It might be suggested that the patient use a hearing aid, which consists of a minute microphone to hear sounds, an amplifier to augment the intensity of the sound and a small speaker that transmits sound to the ear. Cochlear implants are an variety of electronic gadgets which excite the nerve fibers.
The field of medicine faces a test in the form of Sensorineural hearing loss. Hard work is being accoplished to take care of even the toughest of cases. On the brighter side, a number of cases have been treated. In the midst of further research and development there is a likelihood of a cure to loss of hearing, right around the corner.
Treatment of Sensorineural Hearing Loss
The treatment for sensorineural hearing loss is often the use of hearing aids or cochlear implants.
- A hearing aid is a small electronic appliance that fits into the ear. A hearing aid consists of a minute microphone to pick up the sounds, an amplifier that increases the volume and a little speaker that transmits sounds to the ear.
- A cochlear implant is an electronic apparatus implanted behind the ear. Unlike a hearing aid that amplifies sounds; cochlear implants directly excite the acoustic nerve fibers in the cochlea. The implant consists of internal and external apparatus.
- The internal piece is a receiver/stimulator that is to be found under the skin in a bed created in the bone behind the ear. An electrode array, consisting of 22 tiny bands arranged within biocompatible tubing is surgically inserted in the region of one inch into the cochlea.
- The external components consist of a light-weight speech processor and a head-set composed of a directional microphone worn at the back of the ear and a transmitter that is held in place above the set in receiver by diminutive magnets.
