The Audiology Clinic provides diagnostic hearing (audiological) and balance (vestibular) evaluations for outpatients of all ages
Pediatric Audiometric Assessment
Hearing test battery includes pure-tone audiometry with visual-reinforcement or conditioned-play audiometry, speech audiometry, immittance testing including tympanometry and acoustic reflex assessment, and otoacoustic emissions testing, at the discretion of the audiologist. Outpatient referrals are accepted from any medical specialty.
Pediatric Threshold Auditory Brainstem Response (ABR) Testing – non-sedated/ sedated
Non-sedated: Babies typically are referred from newborn hearing screening as mandated by the BC Early Hearing Program (BCEHP) and the testing protocols follow its guidelines. ABR testing provides frequency- and ear-specific hearing threshold information via electrophysiological methods. Children must be sleeping to obtain reliable hearing thresholds.
Sedated: Can be used for children whose results from conventional behavioural audiometry cannot be obtained or are inconclusive. These patients must be referred by a specialist (typically pediatricians or Ear-Nose-Throat physicians). Testing is performed at the Surrey Memorial Hospital’s Child and Youth Services (CYS) Department, where children are monitored by nursing staff throughout testing. Normally, sedation is achieved using chloral hydrate. Referrals, sedation orders and parental consent must be completed by a referring physician with attending privileges at the Surrey Memorial Hospital.
Auditory Processing Disorder (APD) Evaluation
Assessment of central auditory processing abilities in children and adults. Testing includes an audiometric assessment and may include auditory brainstem response (ABR) testing in addition to a central auditory test battery chosen at the discretion of the audiologist. Normal hearing thresholds are required to proceed with the evaluation.
- Parent letter
- Referral Guidelines for pediatric patients
- At least 8 years of age, and expressive and receptive English language skills of at least an 8 year old level.
- A speech and language assessment completed within the last year.
- A psycho-educational assessment completed within the last 2 years.
- An evaluation by a pediatrician regarding the possibility of an attention deficit hyperactivity disorder (ADHD).
- Auditory processing disorder (APD) pediatric questionnaire (for parents to complete)
- Auditory processing disorder (APD) adult questionnaire
Outpatient referrals are accepted from ENT/Neurology/Pediatrics/Psychiatry only. Speech language pathologists may initiate a referral through a specialist.
Please note: Testing is often completed over multiple appointments and results may take several weeks to compile and analyze.
Adult Audiometric Assessment
Hearing test battery includes pure-tone audiometry, speech audiometry, immittance testing including tympanometry and acoustic reflex assessment, and otoacoustic emissions testing, at the discretion of the audiologist.
Outpatient referrals are accepted from any medical specialty.
This type of assessment is offered to individuals who receive potentially ototoxic (harmful to the ear) treatment. These assessments include ultrahigh frequency audiometry and otoacoustic emissions testing in addition to the standard adult audiometric assessment. A baseline audiometric assessment is recommended prior to ototoxic treatment; monitoring during and after treatment is recommended especially if ear-related new symptoms are reported.
Outpatient referrals accepted from specialists serving patients who have been prescribed potentially ototoxic medication (i.e. Oncology/Infectious Disease).
Adult Retrocochlear Auditory Brainstem Response (ABR) Testing
This is an otoneurologic assessment performed in individuals with suspected retrocochlear (beyond the ear) symptoms. This assessment typically is performed in conjunction with a standard audiological assessment. Outpatient referrals are accepted from any medical specialty.
Children may be referred for this assessment provided they are able to lie quietly and still for at least 15 minutes.
Vestibular assessment evaluates inner ear’s balance function; testing includes cervical Vestibular Evoked Myogenic Potential (cVEMP) test, videonystagmography (VNG) (i.e., oculomotor testing, positional/positioning tests, and caloric testing), video Head Impulse Test (vHIT), etc. Additional audiometric assessment may be performed at audiologist’s discretion.
Outpatient referrals are accepted from medical specialists only (typically neurologists and ENTs).
Please note patients’ ear canals should be clear of wax and tympanic membranes should be intact for water caloric test to be carried out.
For outpatients, a specialty physician must complete an outpatient referral form.
