Cochlear Implants for SSD Emma van Wanrooy, SCIC 2nd August 2013
SSD Binaural Hearing Benefits • Head Diffraction Effects • Binaural Squelch • Localisation
SSD • Head Diffraction Effects Binaural Hearing Benefits -SNR +SNR Dillon, 2012
SSD Binaural Hearing Benefits • Head Diffraction Effects • Binaural Squelch • Localisation
SSD • Localisation Binaural Hearing Benefits Dillon, 2012
SSD Also known as unilateral hearing loss A “significant hearing loss in 1 ear” Advisory group for single sided deafness, 2003
SSD Features • Severe to profound • Often sudden onset
SSD • Physical damage /Trauma • Compression of the hearing nerve • Viral or bacterial infections • Disorders of the circulatory system • Severe Ménière’s disease Causes
SSD • Difficulty hearing on impaired side • Poor localisation • Difficulty hearing in noise • Tinnitus Impact
SSD • Hearing Aid (if sufficient hearing) • Cros Aid • Bone conductor • Bone anchored device • eg/ bonebridge Rehabilitation devices
SSD Treatment Until now………….. What about cochlear implants?
SSD Tavora-Vieira et al 2012 • Improvement in speech perception in noise S0N0, SciNhe • Significantly better SSQ scores at 3 months • 1-3 hours/day rehab
SSD • SnhNci speech comprehension better than CROS/BAHA, but not better than unaided. • Better than unaided, CROS and BAHA for SciNnh Arndt, et al, 2010
SSD • Localisation significantly better with CI • SSQ at 6 months post CI significantly better • CI used significantly longer per day • Significant decrease in tinnitus loudness Arndt, et al, 2010
SSD • Definition of ‘SSD’ • Auditory training/ loudness balancing • Music appreciation • Candidacy assessment Further research needed
SSD Personal experiences • 47 year old female • Sudden loss in right ear 18 years prior • Extreme tinnitus
SSD “The hearing in my left ear was perfect and not affected ….the tinnitus .. seemed to mask what my good ear was trying to hear .…a constant challenge to keep my sanity” Personal experiences
SSD . Personal experiences “In harms way when walking up streets with traffic I just couldn’t hear or the direction in which it was coming”
SSD Personal experiences • Referred for BAHA trial and tinnitus counselling • Implanted with Med El Sonata • Tinnitus reported gone instantly
SSD “I’m a lot more balanced and my sense of direction has improved so much it is unbelievable……I now look forward to going out and socialising, I’m more relaxed and am enjoying life more.” Personal experiences
SSD “I experiment by turning my processor off. Huge difference. Can’t wait to turn it back on again…. when I turn it back on it is such a relief. It just feels so much better, so balanced.” Personal experiences
SSD Personal experiences
SSD • Female aged 23 • Musician and singer, studying musicology • Meningitis and lost hearing in Left ear Personal experiences
SSD Personal experiences • Loss of spatial separation of sounds • Difficult to identify sounds that were similar. Eg/ tap running, rain, boiling water
SSD Personal experiences Implanted 15 months later– Med El Sonata Implant using FSP
SSD Personal experiences • At switch on, focussed on loudness and balancing • Did a lot of auditory training
SSD • Improved directional hearing • Good speech understanding • Better able to follow conversation in a group in noise • Mobile phone in noise better Personal experiences
SSD Personal experiences Unable to perform well in musical when batteries went flat in Speech Processor
SSD Take into consideration • Duration of deafness • Goals: • Tinnitus relief • Localisation • Listening in noise
SSD • Relief from severe tinnitus • Improved localisation/ spatial awareness • Improved utilisation of head shadow effects in noise Why CI?
