1. Listening and Spoken Language Outcomes for a Child with an Auditory Brainstem Implant Susan G. Allen, M.E.D., CED., M.Ed., CCC-SLP, LSLS Cert. AVEd
Director, Clarke School for Hearing and Speech / Jacksonville Campus
2. Welcome! A.G. Bell Convention 2010
Little is known about speech perception and spoken language outcomes in children with an Auditory Brainstem Implant who are prelingually deaf.
3. FDA Approval
The only approval for the ABI device in the United States is for children over 12 and adults with Neurofibromatosis-2.
Colletti V. 2005
4. Cochlear Implants
Cochlear Implants are for treatment of patients with severe to profound hearing loss due to cochlear defects with an intact auditory nerve
Colletti V 2005.
5. Auditory Brainstem Implants-ABI
ABI: This device is used for patients with severe to profound hearing loss caused by severe impairment of the cochlear nerve or cochlear abnormalities.
Colletti V 2005.
6. Main differences: ABI vs. CI Patient has a debilitating disease that is life-threatening
Surgery is more complex and much longer
Precise placement of the array more difficult
Side effects during activation to be expected
Stimulation levels to reach audibility generally higher
Outcomes generally poorer
Cochlear Corporation

7. ABI24M Electrode Array 21 contacts. There is no Electrode 1.
Stimulation between contacts can be monopolar or bipolar.21 contacts. There is no Electrode 1.
Stimulation between contacts can be monopolar or bipolar.
8. Known Outcomes ABI recipients should experience:
Detection of medium to loud environmental sounds at comfortable listening levels
Detection of conversational speech at comfortable listening levels
Cochlear Corporation
The ABI can help patients communicate by improving lipreading and hearing environmental sounds.
A small number of patients experience open set understanding.
True benefit often underestimated
Helps recipient cope with their illness
ABI can reduce isolation and improve their quality of life
The ABI can help patients communicate by improving lipreading and hearing environmental sounds.
A small number of patients experience open set understanding.
True benefit often underestimated
Helps recipient cope with their illness
ABI can reduce isolation and improve their quality of life
9. Known Outcomes Most ABI recipients should also experience:
Improved perception of the rhythm and volume of speech resulting in limited improvement in speech recognition and communication ability with lip reading
Limited improvement in the recognition of environmental sounds
A small number of ABI recipients will experience:
Improved speech recognition without lip-reading

10. Case History
A twin born premature at 30 weeks
Hospitalized for 7 months in NICU
Severe profound mixed hearing loss
Craniofacial outer, middle and inner ear abnormalities presented with Goldenhar Syndrome
11. Case History Fitted with BaHA Softband at 4 months
No auditory benefit
MRI at 1 year revealed absence of 7th and 8th cranial nerves and both internal and external auditory canals
Not a cochlear implant candidate
12. Case History Fitted with vibrotactile aid
Child’s audiological team recommended that the family investigate the Auditory Brainstem Implant
13. Case History Auditory Brainstem Implant not approved in the United States
Consulted with Dr. Vittorio Colleti in Verona, Italy
Implanted with ABI at 3 years, 3 months of age
14. Case History Device activated in Italy in January 2006
No follow up until June 2006
Evaluated at House Ear Institute in June 2006 with consultation from Children’s Hospital in Birmingham, AL
No behavioral responses
15. Case History Behavioral responses improved to 25 dB with consistent mapping on June 19, 2006
Received mapping and auditory habilitation at Children’s Hospital in Birmingham
Total communication classroom in the Public School System in Alabama
16. Case History Due to limited progress professionals recommended the family look at other educational options
Visited Clarke Jacksonville in Spring 2007
Enrolled in Diagnostic Summer Program in June 2007

October 2009
May 2010
In the initial evaluation at the beginning of July 2007 (Summer Session)
The above are the results except for APT/HI
On the ESP:
he DID discriminate between /ah/ and hop, hop and 1 vs. 3 syllables
He DID NOT discriminate 2 vs 3 (baby vs. ice-cream cone) or 1 vs. trochee ( ball vs. baby) NO PATTERN PERCEPTION cause stopped with training…
APT/HI was given at the end of the summer session AFTER intervention.
He passed awareness tasks, duration of a single sound short/long, dog vs. hamburger, airplane vs. hamburger but nothing longer, he understood the vowel task of /a/, /u/, /i/ but not diphthongs or consonants. He was on his way!In the initial evaluation at the beginning of July 2007 (Summer Session)

20. Baseline Data Movie of Jorden
21. Components of the Educational Program Classroom that used a “Bottoms up” approach that required remedial instruction with a didactic approach
4 levels of auditory development using the “Circle of Listening”
Association Method
The Dubard “Association Method”
Susan G. Allen “Circle of Listening”
22. Association Method Techniques Used to “jump start” his phonemic awareness skills, articulation and auditory memory
Production of sounds in isolation
Sound segmenting and blending (“boo”)
Segmenting and blending of 3 sounds (boot)
23. What we did differently with Jorden vs. other CI kids Addition of “Association Method"
Rapid drilling with CVC word blends
Rewrites of words and/or phrases
Helped build automaticity of the production of oral language
Auditory Memory Skills
Visual Memory Skills for reading

32. Conclusions Progress was similar to that of a child with a cochlear implant who was implanted at a later age
Surprised the staff with better, steady progress sustained over time than anticipated given available written information on the ABI device
Currently expected to continue to function well in the hearing world with continued auditory-oral education!
