Hearing Aid Styles and Colors - There Are Many!

It is not uncommon that a patient with hearing loss interested in hearing aids mistakenly believe there's only TWO hearing aid styles.

The kind that goes in the ear and the kind that goes behind the ear.

Although that is true, there are more different variations of both types that catches many people by surprise.

There also seems to be a generational gap in what style is preferred by patients.

"Older" folks in their 60's or older prefer the styles that go in the ear, mostly because of the stigma associated with hearing loss and use of a hearing aid that reinforces and reminds them of their age. Also, because they remember the large skin-toned BTE that used to be the only option.

The "younger" generation typically prefer the min-BTE that go behind the ear. It probably helps that so many people use wireless bluetooth earpieces almost like a status symbol.

Beyond where hearing aids go, they now come in different colors and patterns for further personalization! Skin-tone is no longer the only color option.

New Video on Newborn Hearing Testing

Given how often we see newborns in need of hearing testing, we have produced a video showing how the two main types of non-verbal hearing tests are performed today: Auditory Brainstem Response (ABR) and Otoacoustic Emission (OAE).

Given newborns can not communicate whether they can hear or not, such hearing tests depend on the ability to detect nerve signals transmitting sound information from the ear all the way to the brain. This type of test is much like an EKG which can detect the electrical activity of the heart.

Watch the video to see how ABR and OAE hearing testing works in infants (as well as adults)!

Oral Exam Using a Finger

For a good physical exam, physicians use their senses (eyes, ears, nose) to detect disease processes that may not necessarily be obvious to a lay person. Beyond these obvious senses, fingers and hands are also utilized to feel for unusual bumps or masses that may not be obvious to the naked eye.

Take a neck mass for example. Neck masses may not be necessarily visible, but by feeling the neck, may become obvious. To use an analogy, a bowling ball under a mattress may not necessarily be obvious, but if you lay on the bed, would become painfully obvious.

Physicians also use the hands/fingers to examine areas that may not be visible... such as the unpleasant digital rectal exam (inserting a finger up a bung-hole) which is done to detect blood in the stool, rectal/anal cancers, anal muscular incompetence, etc.

However, I find it odd that the mouth is a body area that is not often "felt" around... physicians included.

A finger can appreciate unusual mouth pathology that may not necessarily be appreciated by looking alone. Furthermore, just like the rectal exam, a finger can appreciate base of tongue pathology that cannot be visualized by having a patient go "ah".

I truly feel that actor Michael Douglas would have been diagnosed with his base of tongue cancer much earlier if only a doctor stuck a finger and swept that back area of the tongue. One can "feel" cancer as it is rock hard and very tender. True... it may cause a person to gag, but for a cancer test, it's dirt cheap, fast, and reliable.

However, it does not just have to be areas of the mouth that can not be seen. Even for those ulcerations and bumps of the mouth that one can clearly visualize (or not), it does help to touch it. Is it hard? Soft? Ulcerated? Tender? Grooved? Papillated? Fungating? Rubber-like? Blottable?

Each characteristic provides information to achieve a more accurate diagnosis.

To an ENT way of thinking, if a doctor regularly performs a digital rectal exam, than one can certainly do the same thing at the other end. It's less invasive and provides just as much information.

Say "ah"!!!
