We are used to viewing hearing loss as a gradual impairment, worsening incrementally as we age. However, the sudden onset of hearing loss is actually quite common, and can potentially be resolved without permanent damage if diagnosed and treated quickly. New drugs are currently being tested to treat sudden hearing loss, as well as steroid treatments that have been successful.
Symptoms of Sudden Hearing Loss
Sudden hearing loss is more noticeable than gradual hearing loss because there is a distinct drop in sound information. Sudden hearing loss is defined by a drop of 30 dB or greater in hearing ability over the course of 72 hours or less. The listener may experience tinnitus, a ringing in the ears, a distinct muffling to familiar sounds or difficulties with understanding speech and conversation. Sudden hearing loss can be especially noticeable in comprehending high frequency sounds like children’s voices. Acute hearing loss is most likely to affect only a single ear rather than both ears at once.
It can stem from a variety of causes, and systemic diseases like Lyme disease or syphilis can cause hearing impairment suddenly. Some medications can provoke hearing loss, and infections, circulatory issues and autoimmune problems may also be responsible for loss of hearing.
Our hearing, especially as it relates to the inner ear, is delicate and easily damaged. Problems with inflammation or blood delivery to the inner ear can cause permanent harm to the apparatus of the inner ear. With sudden hearing loss, dramatic loss in hearing ability is a possible sign that something is not working right in the inner ear. If the fragile cells of the inner ear and auditory nerve are not receiving proper blood circulation it can starve and damage them.
Seeking Treatment
These signs of hearing loss shouldn’t be ignored or dismissed. Even if they seem like they could be side effects of a cold or sinus problem, it’s best to get a hearing test to avert potential lasting damage. Sudden hearing loss affects up to 30 people per population of 100,000. The likelihood of hearing loss being temporary increases the sooner you seek treatment. Audiology testing is an important diagnostic tool.
An audiogram can give a detailed and accurate portrait of the range and type of hearing loss experienced. In many cases, blood tests are also performed to look for disease, infection and other toxicology that may be contributing to the hearing loss. A doctor may also request a MRI scan performed to look for acoustic neuroma, which affects up to one in eight patients with sudden hearing loss.
Treating sudden hearing loss is often dependent on finding an underlying cause. For some types of circulatory issues, hearing returns with the use of a steroid gel to encourage robust functioning. A new medication, being tested under the designation AM-111 is currently going through clinical testing to determine its benefit for patients experiencing sudden hearing loss. If the hearing impairment is linked to an underlying disease, infection or medication, medical treatment or adjustment can restore hearing functionality.
When hearing loss happens suddenly, be sure to inform your doctor on your medical history. Because finding the cause of sudden hearing loss is important to effectively treat it, disclosing medication and history is critical to your healthcare.
Other Causes of Acute Hearing Loss
Sudden onset of hearing loss can also occur after exposure to dangerously loud noises or sudden changes in air pressure as well as after injuries to the head. Learn to recognize and protect yourself against dangerous sound levels over 85dB. As decibel levels increase, the lasting harm they can impart on your ears raises exponentially. Sounds like fireworks and gunshots are so loud you should never expose your hearing to them without ear protection. Exposure to dangerously loud sounds often registers as hearing loss accompanied by tinnitus.
Physical impact to your head can have effects on the way you hear. When addressing a head injury be sure to alert your doctor to any changes in hearing you may experience as you recover. The important thing to remember is that hearing is an integral part of your total health and the sooner you address any hearing impairment you may notice, the greater your treatment effectiveness is.
