Details and patient eligibility
About
The purpose of this research study is to learn about the hearing outcomes of adult and pediatric patients who are treated with or are candidates for bone conductive devices (also termed "BAHA"). Hearing outcomes will also be assessed with a second audio processor device called the Adhear System.

Inclusion criteria
Aims 1 and 2:
- Adult English speaking patients who are experienced users of Bone Anchored Implants (BAIs) for the indication of either single sided deafness or conductive hearing loss.
- Experienced will be defined as greater than 6 months of device use and no intermittent function of the device within 2 weeks of enrollment.
- Subjects will be limited to those who have normal hearing by bone conduction defined as a pure tone average of 25 dBHL or better at 500, 1000, 2000, & 3000 Hz in at least one ear.
Aim 3:
- English speaking children 5 to 17 years of age and their primary guardian who present to the clinic for treatment by BAI on a headband device for the indications of single sided deafness or conductive hearing loss.
- Subjects will be limited to those who have no prior use of a BAI or bone conduction hearing device, normal hearing by bone conduction defined as a pure tone average of 25 dBHL or better at 500, 1000, 2000, & 3000 Hz in at least one ear. For those children where this cannot be definitively established, children will be included who display clinical signs of normal bone conduction hearing beyond a reasonable doubt and may include such evidence as (but not limited to): auditory brainstem response, speech awareness thresholds, visual reinforcement audiometry, conditioning play audiometry, CT scans, etc.)
Aim 3 a & b:
- Pediatric bilateral or unilateral conductive hearing loss patients who are between the ages of 2 and 17 years of age
- Pediatric participants who are currently managed by the University of Miami with a bone conduction device attached to a softband.
Exclusion criteria
Aims 1 & 2:
- Non-English speakers
- Participants reporting allergies to adhesives or highly reactive skin.
Aim 3:
- Pediatric participants who are non-English speakers.
- Children who have previous experience with a BAI or bone conduction hearing device will not be included for study.
- Pediatric participants reporting allergies to adhesives or highly reactive skin.
Aims 3a & 3b:
- Pediatric participants who are non-English speakers.
- Pediatric participants reporting allergies to adhesives or highly reactive skin.

66 participants in 6 patient groups
Single-Sided Deafness Adult (Aim1) Group
Experimental group
Description:
Adult participants with single-sided deafness and are experienced bone conduction device users (6 months minimum of bone conduction device use and no intermittent use within the last 2 weeks) with an abutment implant will be provided with the Adhear system for 2 weeks (plus up to 90 days).
Treatment:
Device: Adhear Bone Conduction System
Conductive Hearing Loss Adult (Aim 2) Group
Experimental group
Description:
Adult participants with conductive hearing loss and are experienced bone conduction device users (6 months minimum of bone conduction device use and no intermittent use within the last 2 weeks) with an abutment implant will be provided with the Adhear system for 2 weeks (plus up to 90 days).
Treatment:
Device: Adhear Bone Conduction System
Adhear followed by BAHA (Aim 3) Group
Experimental group
Description:
Pediatric participants (aged 5-17 years) and their parents with conductive hearing loss or single-sided deafness who have not previously used a bone conduction device, will be provided with the Adhear system for 3 weeks (plus up to 90 days) followed by bone anchored hearing aid (BAHA) for another 3 weeks (plus up to 90 days).
Treatment:
Device: Bone anchored hearing aid (BAHA)
Device: Adhear Bone Conduction System
BAHA followed by Adhear (Aim 3) Group
Experimental group
Description:
Pediatric participants (aged 5-17 years) and their parents with conductive hearing loss or single-sided deafness who have not previously used a bone conduction device, will be provided with the BAHA system for 3 weeks (plus up to 90 days) followed by Adhear for another 3 weeks (plus up to 90 days).
Treatment:
Device: Bone anchored hearing aid (BAHA)
Device: Adhear Bone Conduction System
Pediatric Unilateral Conductive Hearing Loss (Aim 3a) Group
Experimental group
Description:
Pediatric participants (aged 2-17 years) and their parents with unilateral conductive hearing loss and are experienced bone conduction device users (6 months minimum of bone conduction device use) on a headband will be provided with the Adhear system for 2 weeks (plus up to 90 days).
Treatment:
Device: Adhear Bone Conduction System
Pediatric Bilateral Conductive Hearing Loss (Aim 3b) Group
Experimental group
Description:
Pediatric participants (aged 2-17 years) and their parents with bilateral conductive hearing loss and are experienced bone conduction device users (6 months minimum of bone conduction device use) on a headband will be provided with the Adhear system. Participants who are fitted bilaterally will receive 2 Adhear systems (one for each ear) for 2 weeks (plus up to 90 days) at Visit 1. Participants who are fitted unilaterally will receive 1 Adhear system for 2 weeks (plus up to 90 days) at Visit 1, afterwards, will be fitted bilaterally at Visit 2 and receive the Adhear system for both ears for another 2 weeks (plus up to 90 days) for a total of 4 weeks (plus up to 180 days).
