Investigating Hearing With Ponto 3 SuperPower, a Bone Anchored Hearing Aid - Investigating Hear
The study is part of the Post Market Clinical Follow (PMCF) activity. The investigational device is the CE-marked Ponto 3 SuperPower (available on the market since December 2016) already fitted to the subjects, and data is collected retrospectively from clinical routine visits.
The study is a retrospective study. Therefore there will be no study visits for treatment or follow-up in the study.
Subject inclusion for this clinical investigation will be performed among subjects who has been fitted with the Ponto 3 SuperPower. To have a wide representative selection of subjects, enrollment will be spread over the 4 years since the device was available on the market since December 2016.
The endpoints in the study will investigate the improvement of hearing with the Ponto 3 SuperPower.
The data will be collected from the subjects in the time period from the clinical routine visit where the Ponto 3 SuperPower where fitted or just prior, and from the clinical routine visit following the fitting, where audiologic fitting follow-up procedures are performed (approximately 3 months).

Ponto 3 SuperPower users
Patients who are fitted either unilaterlaly or bilatterally on abutment since the device came to the market in 2016, and who have follwoed the clinics normal routine fitting and follow up visits. They must also have undergone the normal procedures performed as part of the clinics routine for fitting and following up. Data will be collected from these routine visits. |
Unmasked and if available masked BC thresholds from audiogram obtained prior to Ponto 3 SuperPower were fitted.
BC In-situ thresholds will be collected from the BC In-situ audiogram obtained when Ponto 3 SuperPower were fitted
Sound field thresholds for frequencies 500Hz, 1kHz, 2 kHz, 3kHz and 4kHz will be collected from sound field audiogram obtained as follow-up after Ponto 3 SuperPower fitting, typically this is collected 3 months post fitting, alternatively from the fitting visit.
Thresholds will be obtained aided, and when available unaided
Speech intelligibility is measured in a sound treated room using sentence tests. The sentence tests used at Norwich and Norfolk hospital is the BKB (Bamford-Kowal-Bench) and/or the The AB[s] Isophonemic Monosyllabic Word test (7). The sentence tests are measured in quiet and/or with background speech-weighted noise.
Classification of skin reactions around skin penetrating implants will be made using the Holgers score.
The Holgers classification is a scale from 0 to 4 that is used to grade skin reactions
The Glasgow Benefit Inventory (GBI) contains 18 health status questions, which ask specific questions about how the health problem, in this study hearing loss, has affected their quality of life at the time the GBI is completed.
In this study GBI has been collected on patients before intervention and 3 months after fitting of Ponto 3 SuperPower on abutment.
Average power-on usage hours from Ponto 3 SuperPower will be collected.

Time Frame: Visit 1, Day 1
|
Functional gain with Ponto 3 SuperPower, i.e. the difference between average unaided AC thresholds and aided sound field thresholds for frequencies 500, 1000, 2000, 3000 and 4000 Hz
|
Visit 1, Day 1
|
To assess the improvement of speech recognition in quiet and in noise with Ponto 3 SuperPower on the implanted ear(s) for patients with CHL/MHL

Difference in speech recognition score (%) for speech recognition in noise between unaided and aided when speech is directed to the aided ear, and noise is directed to the non-implanted ear, and when speech is directed to the non-implanted ear, and when noise is directed to the aided ear.
|
Visit 2, 3 months
|
