Causes and Symptoms of Severe Hearing Loss Conductive hearing loss happens because of a problem in the ear canal, eardrum, or the middle ear that prevents sound from carrying well to the inner ear. An ear infection, trauma, a tumor, or fluid or an object in the ear (such as wax buildup) can cause it.

Overview Damage to the inner ear. Aging and exposure to loud noise may cause wear and tear on the hairs or nerve cells in the cochlea that send sound signals to the brain. When these hairs or nerve cells are damaged or missing, electrical signals aren't transmitted as efficiently, and hearing loss occurs.

Slideshow: Top Causes of Severe Hearing Loss Hearing loss is usually caused by problems in the hearing pathway. The problem can be in the outer, middle or inner ear, or in the complex auditory nerve pathway to the brain. Hearing loss can be present at or soon after birth. This is called congenital hearing loss.

Causes of Deafness in Dogs The first step is to understand the leading causes of deafness in canines. Dogs have a well-deserved reputation for keen hearing that can pick up tones undetectable by the human ear. Unfortunately, not every canine has that gift. Hearing loss or total deafness affects many dogs for different reasons. If you’re a dog parent (or considering becoming one) it’s good to understand the following factors that can impact your pet’s hearing.

Hearing Loss Sudden hearing loss, the rapid loss of 30 decibels or more of hearing ability, can happen over several hours or up to 3 days. (A normal conversation is 60 decibels.) Sudden hearing loss usually affects only one ear. Although there are up to 3 new cases per every 10,000 people each year, doctors are not able to discover the cause in most cases. Illnesses such as heart disease, high blood pressure, and diabetes put ears at risk by interfering with the ears' blood supply.

Types of hearing loss If a child is born with sensorineural hearing loss, it is most likely due to a genetic syndrome or an infection passed from mother to fetus inside the womb, such as toxoplasmosis, rubella or herpes. When sensorineural hearing loss develops later in life, it can be caused by a wide variety of triggers, including:

Vestibular Disease or âOld Dogâ Syndrome Peripheral vestibular disease can also be idiopathic, meaning the cause has not been identified. Infection of the middle ear is the most common cause of the disease in younger dogs; in older dogs, brain tumors may be the cause of the disease. Central vestibular disease. Causes of central vestibular disease include:

Otosclerosis Otosclerosis is one of the most common causes of progressive deafness in young adults. 'Otosclerosis is caused by an abnormal growth of bone in the ears, which causes hearing loss. In most cases, a surgical operation will restore the hearing. Otosclerosis has to do with the three small bones in the middle ear, more specifically the stapes. A part of the bone will grow abnormally and this bone growth will prevent the stapes from vibrating normally in response to sound.

How Do You Know If Your Cat Had a Stroke? Last week, we talked about causes of “acute strokes” – or things that look similar – in dogs. In dogs, some causes of “acute stroke” are actually benign causes like old dog vestibular disease. In severe cases, it may be due to malignant causes like a brain tumor. This week, we’ll cover cats and what causes their “acute strokes.” Unfortunately, the causes of “acute stroke” in cats are not often benign as compared to dogs, and are often due to underlying disease.
