Tympanometry Test For People With Hearing Loss Problem

Tuesday, October 31, 2017 9:28:11 PM Asia/Calcutta

Do you know about Tympanometry? Tympanometry is a test done to diagnose the functionality of the middle ear. This is done when a problem in the middle ear is suspected. It has been generally observed that hearing loss goes undetected for a long time. Avoiding embarrassment from peers because of the hearing loss may be a possible reason why many avoid treating hearing loss. However if hearing loss goes untreated for long, the problem only gets worse. It means missing out on important information. It ultimately leads to social isolation and depression thereafter. So a visit to the audiologist is crucial even with the slightest symptom of hearing loss. Hearing Plus is India’s largest chain of hearing aid centers providing professional audiological services to restore hearing problems both for children and adults. In this blog we would explain the facts about Tympanometry.

What is Tympanometry?

Tympanometry is a test to analyze the functioning of the ear drum and the middle ear. The test is conducted by creating air pressure vibrations in the ear canal. It is done to evaluate the transmission levels in the middle ear. Tympanometry helps the audiologist to understand whether the hearing loss is of the sensorineural nature or of the conductive nature. The readings made during the test are recorded on a graph called the Tympanogram. Normally when the air pressures are applied in the ear canal, the ear drums should be able to move easily. But sometimes there may be ear infections inside the middle ear. The Eustachian tube, connects the back of the nose, the throat with the middle ear. This may not work well and the eardrums do not move as well as they should. This gets detected in the Tympanometry test.

The Tympanometry Procedure:

Prior to the actual test the doctor looks inside the ear canal. This is done with a special instrument for looking into the ear, called otoscope. The audiologist does this to ensure that no foreign object is obstructing the eardrum. Following this a probe type device is placed in the ear. Then different ear pressures are generated in the ear. The movement of the eardrums as a result of the application of different air pressures occurs. The measurement of the eardrums along with other readings is noted. During the process the patient may feel a bit uneasy. He or she is likely to hear loud tones as the device starts recording the measurements. The process of Tympanometry can be carried out on young children even. When the procedure is being carried out, the patient is not allowed to speak or swallow. This is to done to avoid any incorrect readings being recorded. Extra care is to be given for children on whom the test is being done. Normal results from the test may be the absence of any fluid in the middle ear, normal movements of the eardrum and conducting bones. If the results are abnormal, it may be because of the presence of fluid in the middle ear. Other abnormalities may be perforation of the eardrum, lack of contact between conduction bones of the middle ear etc.

3 Types Of Hearing Loss

Tuesday, October 31, 2017 8:45:37 PM Asia/Calcutta

The three main section of the ear are termed as the outer, middle and inner ear. The types of hearing loss is generally identified by detecting which section of the hearing pathway is affected. The identification of the affected section in the ear is very important in the determination of hearing loss and hearing loss treatment. Scroll on to know the 3 types of hearing loss.

Conductive Hearing Loss:

Sound waves originating from any source are initially received by the outer ear. Then, it reaches the middle ear. When hearing loss occurs due to the problems in outer or middle ear, it is termed as conductive hearing loss. Such problems mean that the hearing is not conducted properly through the outer or middle ear. Hence, this type of hearing loss is termed as conductive hearing loss. Generally, this type of hearing loss may be cured with proper medication. If not cured with the help of medication or surgery, patients with such problems can be benefited from using a hearing aid, because sound amplification is what that they need the most.

Sensorineural Hearing Loss:

After sound is conducted through the outer or middle ear, it reaches inner ear

(innermost part of the ear). When there is a damage in any part of the inner ear or auditory nerve that connects the inner ear

to the brain, hearing is hugely affected. Such problems can be termed as sensorineural hearing loss. Hearing loss due to disorder in cochlea area of inner ear is of sensory type and if concerning nerve disorders, then it is known as neural. Together it is known as sensorineural hearing loss. It is the most common type of hearing loss.

Though it is a permanent problem, hearing restoration is absolutely possible with the help of hearing aids.

Mixed Hearing loss:

A combination of both conductive and sensorineural hearing loss (problems in both outer/middle and inner ear) is termed as mixed hearing loss. Sometimes, if conductive hearing loss is neglected and left untreated for a longer period, this type of hearing loss occurs. Hearing aids or other hearing devices can help in hearing restoration for most of the patients suffering from this type of hearing loss.

Other types:

Pre-lingual or before learning language/speaking

Post-lingual or after learning language/speaking

Congenital hearing loss or present at birth

Acquired or hearing loss after birth due to one/more reasons

Hearing loss in one ear is termed as unilateral hearing loss

Hearing loss in both ears is termed as bilateral hearing loss

Pure Tone Audiometry (PTA): How It Helps?

Tuesday, October 31, 2017 8:40:19 PM Asia/Calcutta

Do you know about Pure Tone Audiometry (PTA)? How much and what we hear both determine the quality of our lives in many ways. Hearing is an important part of the entire communication process. Yet we often take how much we hear for granted. However hearing loss may often lead to isolation, frustration and even depression. This is why we must always pay sufficient attention to our ability to hear. Since the time wasted on account of hearing loss going unnoticed and undetected in the initial stages, may often prove to be critical in its treatment. So always be alert to this rapidly growing problem of hearing loss. You must be pay sufficient attention to any initial symptoms of hearing loss and visit a good audiologist who can detect any hearing disorders through Hearing Tests. One such very important Hearing test is Pure Tone Audiometry. We at Hearing Plus being the experts about treatment of hearing loss would try to provide you some basic information about the important Hearing Test of Pure Tone Audiometry (PTA).

What is Pure Tone Audiometry (PTA)?

Pure Tone Audiometry is a hearing test which is conducted by the Audiologist to determine the threshold levels of the hearing of an individual. The Pure Tone Audiometry (PTA) is therefore a hearing test which helps the audiologist in gain an insight into the type and the degree of the hearing loss patient. This hearing test is a subjective test where in the participation of the hearing loss patient is necessary. His or her responses are recorded against stimuli during the hearing test.

What To Expect During The Pure Tone Audiometry  (PTA) Test?

During the PTA test the hearing loss patient is placed in a soundproof room. He or she is made to wear head phones. The Audiologist, who generally sits outside the room, controls certain audiometric equipment and first exposes the patient to various types of pitches. The audiologist then tries to analyze whether the patient responds these pitches. The patient is made to respond by raising the hand or pressing a button for the indication. The latter part of the PTA test involves testing of the bone and air conduction in the ears. Both the head phones and head band with oscillators is put behind the patient’s ears to conduct this part of the test. The audiologist tests the results for both type of the conduction and then analyzes which part of the ear is damaged and needs attention.

A typical PTA test normally takes about 20- 25 minutes to be completed. The results of the tests are recorded in an Hearing Test equipment called the “Audiogram”. However as mentioned earlier, since the PTA test is a subjective hearing test, the response of the patient is very important in determining the correct findings from the test. Following the test the audiologist decides on the future course of treatment and what type of hearing device if needed would be suit to raise the hearing levels.

One important point to note about the PTA testing is that the standard of the equipment as well as the competence of the audiologist is of paramount importance for the test. We at Hearingplus being experts in Hearing loss treatment too carry out the PTA test.  For further queries please visit www.hearingplus.in

Hearing Aid Price

Tuesday, October 31, 2017 8:23:44 PM Asia/Calcutta

Hearing Aid prices in India may range from Rs. 3000 to Rs. 2.5 lacs. Several parameters determine the hearing aid prices. In a study done by Silva et. al. (2012) two important determinants of hearing aid prices are:

  1. Style or Design of Hearing Aid
  2. Signal Processing Technology

There are some other parameters which directly contribute to hearing aid prices and those are directional microphone, hearing aid shells and noise cancellation circuitry.

Now the question comes how a person will determine what value of hearing aid to purchase.

Definitely the type and degree of hearing loss is one of the key factors to determine the hearing aid which is usually determined by an Audiologist. Another key factor that an Audiologist keeps in mind while selecting a hearing aid is the lifestyle of the said person. In this parameter the said person with hearing impairment can contribute in the selection process and on the hearing aid price.

Based on the lifestyle that the person wants to enjoy he can select the appropriate type of hearing aid.

For example two person with the same degree and type of hearing loss and both are aging 65 years. Person A enjoys a sedentary life basically and mostly stays at home and person B is very active socially so person A should select hearing aid that supports simple living and hence his cost of hearing aid will be cheaper compared to person B who should select hearing aids supporting outdoor living or vibrant living and hence his hearing aid will be costlier.

All You Need To Know About Your Cochlear Implant Surgery

Tuesday, October 31, 2017 7:15:21 PM Asia/Calcutta

Cochlear implant surgery has become a very common medical procedure worldwide. The operation is used as a corrective procedure for severe to profound sensorineural hearing loss in patients. The decision for the medical procedure is taken by parents or legal guardians for children and by the adults themselves.

The cochlear implant surgery is a 60 – 75 minutes procedure and it is carried out in the outpatient department. Before the medical procedure is conducted by a surgeon, a general medical history of the patient is drawn. This medical history also includes the issues leading to hearing loss and the ultimate decision to undertake the surgical corrective measure.

A complete otolaryngologic and neuro-otologic test are carried out to ascertain the different issues with your ear first. A typical test would be conducted by an audiologist who will measure the performance of your ear with or without your hearing aid. Sometimes OAE (optoacoustic emission) testing reveals the need to undertake trials with a stronger hearing aid than being currently used by you.

In case of children, pure-tone audiometry and auditory brain stem response (ABR) testing is done often. A CT scan is used to obtain the status of the cochlea in order to identify a common cavity, mondini dysplasia (enlarged vestibular aqueduct) or a patent (nonossified) cochlea.

In several circumstances, an MRI is conducted on patient to determine the presence of the eighth nerve or severe ossification. Then a psychological examination is conducted on the patient to see if the patient can cope with the surgical procedure of cochlear implant.

Once clearance from other tests is given, a physical test is conducted to prepare the patient for cochlear implant. After the cochlear implant procedure is conducted the patient may feel the following:-

  1. pressure or discomfort over his (or her) implanted ear
  2. dizziness and  nausea
  3. temporary disorientation or confusion
  4. a sore throat for a while from the breathing tube used during general anesthesia

A person suspecting problems of hearing loss should contact any hearing aid clinic in India. These clinics provide a one stop shop for all your hearing issues and have sufficient infrastructure, relevant professionals and testing facilities all under one roof sparing you the hassle of running around the city from one place to another. The hearing aid clinics in Kolkata are currently using more advanced machinery and testing facilities. These hearing aid clinics are no less well equipped than clinics for hearing aid in Delhi.
