Hearing Evaluations

Diagnostic Hearing EvaluationsDiagnostic Hearing Evaluations

Our staff of licensed audiologists are highly skilled and trained to evaluate hearing capacity and hearing loss. After the initial diagnostic evaluation, CNC Hearing and Balance Medical Director, Moises Arriaga, MD, evaluates hearing loss to rule out other possible causes of hearing loss. A treatment plan is then developed to address the patient’s needs.

There are two main components of a diagnostic hearing evaluation:

Pure-tone Air and Bone Conduction testing is a useful test to determine the softest sounds a person can hear at different frequencies, or pitches. It also helps to pinpoint the site of the hearing loss—outer ear, middle ear, or inner ear.  Speech Testing determines both the softest level a person can understand words and how well a person can understand conversational speech. Together, these measurements and tests complete a picture of one’s hearing health, and are the foundation we use to develop a treatment plan in order to enhance a person’s communication abilities.

Our comprehensive evaluation also includes:

  • Otoscopy –
    Examination of the ear canal
  • Tympanometry –
    Measurement of ear drum movement
  • Acoustic Reflexes –
    Assessment of middle ear muscles and the hearing nerve
  • OAEs –
    Assessment of function of hair cells in the inner ear

Dr. Arriaga is then consulted if it appears there might be a medical reason for the hearing loss. Some general areas of further evaluation include:

  • Electrocochleography (ECochG) – Evaluates for possible hydrops of Meniere’s disease
  • Auditory Brainstem Evoked Response (ABR)  – Estimates hearing sensitivity and identifies neurological abnormalities of the auditory nerve and pathway
  • Magnetic Resonance Imaging
  • Computerized Tomography (CT) Scan

Comprehensive Balance Assessments

When diagnosing a balance disorder, it is important to identify and treat the underlying cause and to coordinate with other medical specialists, when necessary. For example, our staff frequently coordinates with  neurologists on conditions that affect balance, such as migraine-related balance issues. We also work closely with neurosurgeons dealing with tumors that can cause balance issues.
