Fluid collecting in the middle ear can lead to a sense of pressure and fullness in the ear as well as a temporary hearing loss, as sounds can’t be transmitted effectively to the inner ear
through the fluid. If the fluid gets infected, you’ll also notice lots of pain, which may be accompanied by a fever. If you think you have a middle ear infection, you’ll definitely want to
see your primary care physician or an ENT, because you may need oral antibiotics to treat the ear infection. Middle ear infections can most often be triggered by getting a cold or having
nasal allergies. In these cases, the lining of the nose and the back of the throat can get swollen and inflamed, which blocks the opening around the Eustachian tube, preventing air from
getting back and forth. The good news is that the hearing loss caused by a middle ear infection is only temporary until the infection resolves and the fluid in the middle ear drains out
through the Eustachian tube. 3. INNER EAR INFECTIONS Unlike external and middle ear infections, which are relatively common and have symptoms that resolve after being treated, inner ear
infections are relatively rare and far more dangerous to your hearing. The inner ear is generally resistant to ear infections, since it’s hard for bacteria and viruses to get into and infect
the fluid of the inner ear. Unfortunately, while it’s rare, scientists estimate that about 1 in 10,000 to 50,000 people a year get inner ear infections. In these cases, doctors think that
most commonly some type of virus manages to get into the inner ear and damage the inner ear, leading to a sudden loss of hearing. Not surprisingly, it’s called a sudden sensorineural hearing
loss (SSNHL — ear doctors have absolutely no imagination or creativity when it comes to naming diseases!). SSNHL is an urgent medical condition. The earlier it’s diagnosed and treated
(ideally within three to five days), the better the chance of some recovery of hearing. The key thing to note about an SSNHL is that the hearing loss comes on suddenly — over a period of
minutes — and often completely out of the blue in just one ear. In contrast, hearing loss from an external or middle ear infection is not nearly so sudden or severe, is often accompanied by
other symptoms, and may affect both ears. If you experience a sudden change in hearing, see an ear, nose, and throat doctor (ENT) immediately. TYPES OF HEARING LOSS * SENSORINEURAL HEARING
LOSS is the most common type of hearing loss, caused by cellular damage in the inner ear. It can be treated with communication strategies, hearing aids, or cochlear implants, but it is not
reversible by any pharmacologic or surgical intervention at this time. * CONDUCTIVE HEARING LOSS is when sound cannot get to the inner ear to be encoded and sent to the brain. Examples of
conductive hearing loss include external and middle ear infections, impacted earwax, fluid in the ears, or a growth in the middle ear space — anything that blocks sound from getting to the
inner ear. An ear, nose, and throat doctor (ENT) can correct many conductive losses. * MIXED HEARING LOSS is when an individual has both sensorineural and conductive hearing loss. For
example, a person may have a mild sensorineural hearing loss but then gets a cold that causes the middle ear space to fill with fluid, which prevents sound from getting to the inner ear.
