Outcomes of Group Aural Rehabilitation For Older Adult Cochlear Implant Recipients

More older adults are getting cochlear implants. Research has shown that working on listening skills after surgery in a group setting can be very beneficial. However, finding a group rehabilitation setting can be difficult. This study provides older adults with a rehabilitation group, led by an audiologist and a speech pathologist. Patients involved will be able to share their experiences, difficulties, and solutions with other group members. Clinicians will provide resources for support. The clinicians will be able to measure the benefit the group provides on cochlear implant performance and quality of life. Due to COVID 19 precautions, this group will be held virtually. Learn more.

Implementation of Cognitive and Hearing Handicap Measures Into Cochlear Implant Candidacy

There is a relationship between hearing loss and cognition. Research has shown an increased risk of dementia for those with severe hearing loss. It is not yet clear if cochlear implantation can improve cognitive function. This study examines patient performance on a cognitive screening tool before and after implantation. Patient perception of hearing handicap is also measured pre- and post-surgery. Learn more.

Clinical Use of Electrically Evoked Stapedial Reflex Threshold Measures for Cochlear Implant MAPping Optimization

Programming, or MAPping, cochlear implants has always been subject to the variability of the user’s response and the audiologist’s skill. The electrically evoked stapedial reflex threshold (eSRT) is an objective measure that has been shown to be useful in determining the upper loudness limits of a cochlear implant program. This leads to streamlined programming across clinics and among audiologists. In addition, patients who use programs created with eSRT often perform better than with their older MAPs.

Intra- and Post-Operative Measures of Auditory Function Using Cochlear Implants

Today, individuals with good low frequency hearing can still be candidates for a cochlear implant. During surgery, our surgeons work to preserve as much hearing as possible. Use of an objective response, known as Electrocochleography (ECochG), can help. Advanced Bionics, one of the three FDA approved cochlear implant manufacturers in the US, has developed a system that allows the surgeon to monitor the ECohG during surgery to maximize persevered hearing.

Cochlear Implantation Outcomes in the Advanced Geriatric Population

There has been a significant increase in life expectancy in the last several years with many older adults living healthy lives well into their 80s and beyond. With that aging population, there are also many older adults seeking cochlear implants as they have developed severe hearing loss that cannot be benefited with hearing aids. While there is good data supporting cochlear implants in older adults, there are few studies that assess outcomes amongst the older adult population. This study assessed the outcomes comparing an older adult population (60-74) to a more advanced geriatric population (75+). The study determined that with both objective and subjective measures that advanced geriatric patients gained equal benefits to the younger patients. This research supports the concept that age alone should not be an exclusionary factor for cochlear implant consideration. Learn more.

Late Implantation of a Child with Eighth Nerve Deficiency

The benefit of cochlear implantation in children with eighth nerve (hearing nerve) deficiency has been well-documented. However, lack of hearing stimulation can impact outcomes in any child with hearing loss. This case report examined the responses of a child with eighth nerve deficiency who received a cochlear implant at a delayed age of four years of age. In spite of receiving late implantation, this child demonstrated significant development of oral language by utilizing the cochlear implant and receiving intensive oral speech therapy services.  Learn more.

Unilateral Cochlear Implantation in Older Children: Two Case Studies

Cochlear implantation in patients with hearing loss in only one ear is being done in increased frequency. There has been significant research on adults receiving cochlear implants with unilateral hearing loss, but fewer studies assessing unilateral implantation in children. This case study assessed the postoperative scores of two older children receiving cochlear implant with unilateral hearing loss.  Learn more.
