1
Tympanometry Protocols Used In Early Intervention
Services In the United States A Pilot Survey of
Early Intervention and Pediatric Audiologists
  • Wendy D. Hanks, Ph.D.
  • Molly A. Kinder, M.S.
  • Gallaudet University

2
The Purpose
  • What tympanometry protocols are being used?
  • Is the 1000 Hz probe tone in use?
  • Audiologists 1000 Hz probe tone knowledge?

3
Our Respondents
  • Sent survey via email on
  • EHDI listserve
  • Educational Audiology Association listserve
  • AAA SoundOff listserve
  • 153 audiologists responded

4
The Survey
  • Began with demographics
  • 13 male 87 female
  • 35 states, Washington D.C., and the Commonwealth
    of the Marina Islands represented

Current Studies and Data
  • In 2003, two studies published with normative
    data for 1000 Hz tympanometry
  • Kei et al., 2003
  • SAA compensated at 200 daPa
  • Refer if SAA less than .39 ml
  • Margolis et al., 2003
  • SAA compensated at -400 da Pa
  • Refer if SAA less than .6 ml

1000 Hz Probe Tone Use

Is 1000 Hz Tympanometry Useful With Children 0-6
Months?
26
Additional Information26 of 153 respondents
  • 1000 Hz tympanometry is crucial/important in the
    testing of young children (6)
  • Do not have the capability of 1000 Hz probe tone
    (7)
  • Interpretation of 1000 Hz can be difficult (4)
  • The protocol for using immittance was described
    (3)
  • 1000 Hz data is needed (2)
  • Use 1000 Hz as a cross check only (1)
  • 226 Hz can be used reliably with the infants
    population (1)
  • Could not answer all the technical questions (1)
  • "I work part-time and don't see many children
    (1).

27
Conclusions
  • Further study of this topic is needed
  • More training on the appropriate use of
    tympanometry is needed
  • 1000 Hz tympanometry normative data should be
    used consistently
