Frequently Asked Questions

Otolaryngology is the medical specialty concerned with disorders and conditions of the ear, nose, and throat (ENT) region of the body. If you have a problem related to these body areas, your regular primary care doctor may refer you to an ENT specialist.

What is an ENT?

An ear, nose, and throat specialist, also known as an ENT or otolaryngologist, is a doctor who possesses a set of specialized skills. Those who work within this field diagnose and treat a wide variety of conditions related to the ears, nose, and throat. ENTs may treat acute conditions, or they may work in primary care, providing services to both adults and children.

When a condition is severe, the ENT doctor determines the cause and then finds the right method of treatment for the individual. Otolaryngology specialists also provide checkups, perform surgeries, and test for many diseases associated with the head.

What conditions do ENTs treat?

There are numerous ear-related conditions that are treated by ENT doctors. When working with the ears, these doctors identify, evaluate, and correct many clinical problems. They use different devices or surgery to treat conditions such as hearing loss, ear infections, nerve damage, malformations, balance disorders, and even birth disorders that affect both the inner or outer area of the ear.

Problems involving the nose are also treated by ENTs, such as deviated septum, malformation, nerve disorders, chronic sinusitis, and smell and sensory issues. They can also treat allergies and breathing problems that are the result of a problem with the nasal cavity.

Treatment of the throat area involves cancer, speech problems, and vocal issues, as well as eating disabilities and speaking limitations. ENTs also treat infections of the throat that are acute or chronic, and perform surgery as necessary.

What services do ENTs offer?

ENTs use different tools, devices, and techniques in order to detect problems occurring within the ear, nose, and/or throat. Through diagnostic measures, the doctor can find the root of the problem and determine the best method of treatment. These specialists treat various health conditions through the use of medication, medical devices, and in some cases, they use corrective surgery. ENTs often find it necessary to operate because of an internal issue or to provide reconstructive surgery on congenital birth defects.

What to expect from an ENT appointment?

The ears, nose and throat are important parts of the body. When issues occur within these areas, it affects the senses and lead to a developmental delay for a young child. At the first appointment, you can discuss any issues present with you or your child with the doctor, and the specialist will perform a variety of tests in order diagnose the problem. These tests include visual exams, hearing tests, tympanograms, and laryngoscopes. After testing is complete, the ENT doctor will discuss the results with you and set up a treatment plan.

Common Questions Related To Hearing Loss and Hearing Care


How Do I Know if I Have Hearing Loss?

If you think you or a loved one may have hearing loss, you are not alone. Often times people notice signs of hearing loss but do not take the steps to get it treated right away. Typically, it takes people an average of seven years to seek treatment. You may have hearing loss if:

  • You hear people speaking but you have to strain to understand their words.
  • You frequently ask people to repeat what they said.
  • You don’t laugh at jokes because you miss too much of the story or the punch line.
  • You frequently complain that people mumble.
  • You need to ask others about the details of a meeting you just attended.
  • You play the TV or radio louder than your friends, spouse and relatives.
  • You cannot hear the doorbell or the telephone.
  • You find that looking at people when they speak to you makes it easier to understand.
  • You miss environmental sounds such as birds or leaves blowing.
  • You find yourself avoiding certain restaurants because they are too noisy, or certain people, because you cannot understand them.
  • You hear a ringing sound in your ears, especially when it is quiet.

What Causes Hearing Loss?

Hearing loss can be due to several factors such as the aging process, exposure to loud noise, medications, infections, head or ear trauma, congenital (birth) or genetic factors, diseases, as well as a number of other causes. Recent data shows that about 20 percent of adults in the United States (48 million) report some degree of hearing loss. Hearing loss often occurs gradually throughout a lifetime.


How is Hearing Loss Diagnosed?

If you have any symptoms of hearing loss, you should see an audiologist to have a formal hearing evaluation. This hearing test, or audiologic evaluation, is diagnostic in nature and allows the audiologist to determine the type, nature and degree of your hearing loss. Your sensitivity, acuity and accuracy to speech understanding will be assessed as well. Your audiologist may also test for speech understanding at different volume levels and in different conditions, such as noise, to provide an indication as to how successful of a candidate you will be for hearing aids.

The hearing evaluation will also include a thorough case history and a visual inspection of the ear canal and eardrum. Additional tests of middle ear function may also be performed. The results of the evaluation can be useful to a physician, if the audiologist believes your hearing loss may benefit from medical intervention.

Results of the hearing evaluation are plotted on a graph called an audiogram. The audiogram provides a visual view of your hearing test results across various pitches or frequencies, especially the ones necessary for understanding speech.

The audiogram and results from your speech understanding tests are used to create a prescription by which hearing aids are programmed, if necessary.


What Are The Different Degrees of Hearing Loss?

After you undergo a hearing evaluation, the results are plotted on a chart called an audiogram. Loudness is plotted from top to bottom. The top of the graph is very quiet and the bottom of the graph is very loud. Frequency, or pitch, from low to high, is plotted from left to right. Hearing level (HL) is measured in decibels (dB) and is described in general categories, not by percentages. The general hearing loss categories used by most hearing professionals are as follows:

  • Normal hearing (0 to 25 dB HL) Mild hearing loss (26 to 40 dB HL)
  • Moderate hearing loss (41 to 70 dB HL)
  • Severe hearing loss (71 to 90 dB HL)
  • Profound hearing loss (greater than 91 dB HL)

What are the Different Types of Hearing Loss?

There are four types of hearing loss:

1. Sensorineural hearing loss: When the problem is in the inner ear, a sensorineural hearing loss is the result. This commonly occurs from damage to the small hair cells, or nerve fibers, in the organ of hearing. Sensorineural hearing loss is the most common type of hearing loss and accounts for more than 90 percent of hearing loss in all hearing aid wearers. The most common causes of this hearing loss are age-related changes and noise exposure. Loss may also result from disturbance of inner ear circulation, increased inner ear fluid pressure, or from disturbances of nerve transmission. There are many excellent options for the patient with sensorineural hearing loss.

2. Conductive hearing loss: When there is a problem in the external or middle ear, a conductive hearing impairment occurs. Conductive hearing loss occurs when sound is not conducted efficiently through the ear canal, eardrum, or tiny bones of the middle ear, resulting in a reduction of the loudness of sound that is heard. Conductive losses may result from earwax blocking the ear canal, fluid in the middle ear, middle ear infection, obstruction of the ear canal, perforation (hole) in the eardrum membrane, or disease of any of the three middle ear bones. All conductive hearing losses should be evaluated by a physician to explore medical and surgical options.

3. Mixed hearing loss – When there are problems in the middle and inner ear, a mixed hearing impairment is the result (i.e. conductive and a sensorineural impairment).

4. Auditory neuropathy spectrum disorder (ANSD): The least common hearing impairment is ANSD. This type of loss requires more in-depth diagnostic testing, including a hearing evaluation with pure tones, otoacoustic emissions (OAEs) and auditory brainstem response (ABR) testing. In this type of hearing loss, the nerve fibers in the organ of hearing typically appear to be functioning well, but a breakdown of the information occurs along the pathway to the brain. A person may still have normal hearing to sounds, but the sound is not encoded properly the brain. This type of hearing disorder is diagnosed more often in children, due in part to newborn hearing screenings that use automated ABR equipment and routine speech screenings by pediatricians and school systems, but can be present in adults as well.


What are the Signs of Hearing loss in Children?

Hearing loss in children can occur from birth to from other acquired factors in life such as ear infections, head trauma, certain medication and genetic factors. You may suspect your child has a hearing loss if you observe any of the following:

  • Failed newborn hearing screening
  • Delays in speech and language acquisition, including baby babbling
  • Frequent ear infections
  • Not startling to loud sounds
  • Not turning to the location of sounds after six months of age
  • Difficulty following verbal directions
  • Daydreaming in many situations
  • Concerns by school teachers or failed school hearing screening
  • Loud volume on the TV or radio
  • Complaints from the child that they cannot hear

A pediatric audiologist is trained to test children of all ages. Any symptom of hearing loss in children should be addressed promptly so that speech, language and academic development are not delayed or impacted.


What is Tinnitus?

Tinnitus is a common disorder affecting over 50 million people in the United States. It is often referred to as “ringing in the ears,” although some people hear hissing, roaring, whistling, chirping, or clicking. Tinnitus, often called head noise, is not a disease, but a symptom of another underlying condition of the ear, auditory nerve, or elsewhere. Tinnitus can be intermittent or constant, with single or multiple tones. Its perceived volume can range from very soft to extremely loud.


What Causes Tinnitus?

The exact cause of tinnitus is not known in every case. However, there are several likely factors which may cause tinnitus or make existing head noise worse. These include:

  • Noise-induced hearing loss
  • Wax build-up in the ear canal
  • Certain medications
  • Ear or sinus infections
  • Age-related hearing loss
  • Ear diseases and disorders
  • Jaw misalignment
  • Cardiovascular disease
  • Certain types of tumors
  • Thyroid disorders
  • Head and neck trauma

How is Tinnitus Treated?

Generally, most patients will not need any medical treatment for tinnitus. There are several treatments and measures to help with the management of tinnitus including:

  • Listening to a fan or radio
  • Tinnitus masking devices
  • Biofeedback training
  • Avoidance measures
  • Avoidance of certain medications
  • Hearing aids, if the listener also has a hearing loss

If these measures do not work, there are several medications that have been utilized to suppress tinnitus. Some patients benefit with these drugs and others do not. Each patient has an individual response to medication, and what works for one patient may not work for another.
