Audiology Diagnostic Testing

At Maryland ENT our audiologist offer a wide range of diagnostic testing. Listed is a list of the main testing performed at our offices:

Hearing Examination:
The audiogram determines hearing levels and type of hearing loss.
Audiometric pure tone and speech testing is performed. Tympanometry evaluates mobility of the eardrum and status of the middle ear. Otoacoustic Emission (OAE) testing evaluates the function of the outer hair cells in the cochlea (the hearing organ). The audiologist will discuss the results of the hearing evaluation with the individual and determine what treatment is necessary, such as hearing aids or a medical referral to our ENT physicians.

Auditory Brainstem Response (ABR): Evaluates how well sound travels from the auditory nerve to the lower brainstem. An ABR is recommended to rule out any lesion along the hearing nerve that may cause asymmetric hearing loss, ringing in the ears, and/or dizziness. To complete the ABR test, electrodes are placed on the forehead and soft earplugs are inserted into the ear canals. The individual will hear moderate to loud clicking sounds. The individual is instructed to be still, quiet, and relaxed during this test. This test takes approximately 30 minutes.

Eletrocochleography (EcoG): Evaluates the inner ear in suspected cases of Meniere’s disease and other disorders of the inner ear. This test is completed on individuals complaining of spontaneous episodes of vertigo or dizziness, which may or may not be accompanied by tinnitus (ringing/humming/buzzing in the ear/s) and fluctuating hearing loss.

To complete the EcoG test, electrodes are placed on the forehead and soft earplugs are inserted into the ear canals. The individual will hear moderate to loud clicking sounds. The individual is instructed to be still, quiet, and relaxed during this test. This test takes approximately 30 minutes.

Electronystagmography (ENG): Evaluates the status of the vestibular (balance) system in the inner ear. Eye movements are recorded and used to determine the status of the inner ear. This test is completed on individuals complaining of vertigo, dizziness, lightheadedness, or loss of balance. There are many types of medical conditions that can cause these symptoms. Benign Paroxysmal Positional Vertigo (BPPV) is a common cause of vertigo. Individuals with BPPV often complain of dizziness when they rotate their head. This type of positional vertigo is usually treated in one or two visits by the audiologist.

The ENG consists of a series of non-invasive tests in which electrodes are placed on the patients face (forehead and next to the eyes). There are pre-test instructions that must be followed 48 hours prior to ENG testing. This test takes approximately 1 hour.

HEARING AIDS

Our audiologists work with the latest hearing aid technologies from a variety of hearing aid manufacturers. Hearing aids today are digital and programmable. They allow us to fit you with a device that is matched specifically to your hearing levels. This allows the hearing aids to grow with you as your hearing changes; instead of new devices the audiologist simply reprograms your current ones to your new hearing levels.

There are different levels of hearing aid technologies. Our audiologists will go through a hearing aid evaluation with you that will help you decide what hearing aid technology and style will work best for your lifestyle and hearing levels.

Below are examples of what some of the different styles of hearing aids look like. There are advantages and disadvantages to each style and those will be discussed during your evaluation.

Hearing Aid Styles:

Behind the ear (BTE)
This hearing aid sits behind the ear with a thin tube/wire that runs down in front of the ear with a rubber tip or a customized mold that inserts into the ear. This style can fit hearing losses between mild and profound.

In the Ear (ITE)
This hearing aid sits totally in the ear and fills up the entire bowl of the ear. It is customized from a mold of your ear taken by the audiologist. It fits mild to severe hearing losses.

In the Canal (ITC)
This hearing aid sits in the lower portion of the bowl of the ear. It’s customized from a mold of your ear taken by the audiologist. It fits mild to moderate hearing losses.

Completely in the Canal (CIC)
This is the smallest of the hearing aid styles. It sits completely in the ear canal. It’s customized from a deep mold of the ear taken by the audiologist. It fits mild to moderate hearing losses.
