TYMPANOMETERS 

A tympanometer gives hearing care professionals the ability to assess the function of the middle ear. GSI tympanometers include fully clinical and diagnostic instruments, screening devices with limited testing capabilities, handheld or portable options, and combination devices that have more than one modality. The type of tympanometer used in each facility depends on the patient population and specific testing needs. A clinical middle ear analyzer will be the most versatile and includes predefined test types such as tympanometry with multiple probe tones, Y, B, and G immittance options, reflex threshold testing, reflex decay, ARLT, Multi Hz, and ETF tests (intact, patent, patulous). Diagnostic tympanometers allow for basic tympanometry, ipsilateral acoustic reflex testing, and sometimes have the option to upgrade to specific special tests such as contralateral reflex testing or additional probe tones. Screening and handheld tympanometers are limited to basic testing capabilities.

TYMPSTAR PRO | CLINICAL TYMPANOMETER

The GSI TympStar Pro™ offers comprehensive middle ear testing that supports the needs of hearing healthcare professionals in a variety of clinical settings. Change parameters on the fly and interpret results using the touch screen display. Protocols may be configured to optimize efficiency and workflow. Multiple protocols may be created and assigned to individual users in clinics with multiple practitioners, for maximum efficiency. Reliability, versatility, and confidence in testing are the hallmarks of any GSI tympanometer, including the TympStar Pro. A redesigned shoulder probe and the touch screen display allow hearing healthcare professionals to easily change test ears and test parameters quickly and efficiently. The TympStar Pro continues to be the gold standard for clinical immittance.

GSI 39 | TYMPANOMETER & AUDIOMETER

The GSI 39™ Auto Tymp provides a flexible screening product for tympanometry, acoustic reflex measurements, and audiometry to meet testing needs today and in the future. The product is available in five different versions to address the unique demands of each facility, such as primary care physicians, schools, or satellite offices. All five versions are fast, versatile, and easy to use. It is possible to add additional modalities such as audiometry, contralateral reflexes, or 1000 Hz probe tone as the facility testing requirements expand. A special “combo” probe is an available option with all versions that combines both 226 Hz and 1000 Hz measurement capabilities. Both infant and adult normative ranges may be selected as a guide on the display and printouts.

TYMPANOMETRY BASICS

WHAT DOES BASIC TYMPANOMETRY TESTING INCLUDE?
Tympanometry is the graphic representation of the acoustic mechanical function of the middle ear. When a pressure sweep is applied to the ear canal, the movement of the middle ear system is displayed. Tympanometry can be performed for screening or diagnostic purposes. Middle ear testing assists in determining the site of lesion of a hearing problem.

WHAT TYPES OF ENVIRONMENTS ARE TYMPANOMETERS USED IN?
Tympanometers are used by hearing care professionals in facilities where hearing testing is performed. This may include clinical settings, academic institutions, or health offices. Diagnostic tympanometers are used in an environment that is appropriate for detailed middle ear testing and can be found in the offices of audiologists and ENT physicians, hospitals, medical centers, and universities. Screening tympanometers are very portable and can be used in a variety of environments such as schools, physicians’ offices, or other healthcare clinics.

WHAT IS THE AGE RANGE OF PATIENTS THAT MAY NEED TYMPANOMETRY TESTING?
Tympanometry is performed on patients of all ages, from newborns to geriatrics. Tympanometry is used on infants and children to confirm ear infections and fluid in the middle ear. A complete middle ear evaluation, including tympanometry, will be performed on adult patients to verify acoustic mechanical function of the middle ear system and neural integrity.

WHAT WILL A TYMPANOGRAM TELL YOU?
The tympanogram provides an objective evaluation of the middle ear and includes measurements of peak pressure, eardrum compliance, and ear canal volume, which will assist in the interpretation of the tympanogram. These measurements help identify or rule out conditions such as fluid buildup, a middle ear infection, or a perforated eardrum, that could contribute to hearing loss.
