Investigating Hearing With Ponto 3 SuperPower, a Bone Anchored Hearing Aid - Investigating Hear

August 7, 2025 updated by: Oticon Medical

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).

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Ponto 3 SuperPower users

Patients who are fitted either unilaterally or bilaterally on abutment since the device came to the market in 2016, and who have followed 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 was 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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Functional Gain Thresholds: Unaided Air Conduction (AC) Thresholds Compared to Aided Bone Conduction (BC) Thresholds, in Ponto 3 SuperPower Users With Conductive Hearing Loss (CHL) and/or Mixed Hearing Loss (MHL).
Time Frame: Visit 2, 3 months

Functional gain is the difference between the average unaided threshold measured across the frequencies of 500, 1000, 2000 and 4000 Hz and the average aided (i.e. with the Ponto 3 SuperPower) threshold measured across the frequencies of 500, 1000, 2000 and 4000 Hz.

For bilaterally fitted patients, the best ear is selected.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Functional Gain With the Ponto 3 SuperPower for Patients With CHL/MHL.
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. For bilaterally fitted patients, the best ear is selected.
Visit 1, Day 1
Improvement of Speech Recognition in Quiet and in Noise With Ponto 3 SuperPower for Patients With CHL/MHL
Time Frame: Visit 2, 3 months
Aided speech recognition (% correct words) measured in quiet and in noise with the BKB sentence test and the AB[s] short list test averaged across patients. Only participants with data for both visits were included in analysis.

Time Frame: Visit 2, 3 months

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.

Aided and unaided speech recognition (% correct words) measured with the AB[s] short list.

Degree of Compensation for Hearing Loss on the Implanted Ear(s) With the Ponto 3 SuperPower for Patients With CHL/MHL.
Time Frame: visit 2, 3 months
Effective gain with Ponto 3 SuperPower, i.e. the difference between aided sound field thresholds and the BC In-situ thresholds on the aided ear(s) measured when the Ponto 3 SuperPower(s) was fitted. The effective gain is calculated as the average (PTA4) of frequencies 500, 1000, 2000 and 4000 Hz. Only participants with data for both study visits were included in the analysis.

Quality of Life Improvements With the Ponto 3 SuperPower
Time Frame: Visit 2, 3 months

Glasgow Benefit Inventory (GBI) total score per target population.

The GBI consists of 18 items, each on a 5 point Likert scale. Responses are scaled and averaged to give a score with a range -100 (poorest outcome) through 0 (no change) to +100 (best outcome).

Visit 2, 3 months
Individual Level Evaluation of Objectives 1-6; Improved Hearing
Time Frame: Change between visit 1 (day 1) and visit 2 (3 months)t of study

Improved hearing was analyzed as the percentage of subjects whose performance is better or equal in the unaided to aided comparisons, i.e., have a difference ≥0.

Functional gain was used for CHL/MHL patients and speech recognition in noise was used for SSD patients.

Change between visit 1 (day 1) and visit 2 (3 months)t of study
Air to Bone Gap (PTA3) on the Implanted Ear(s) for Patients With CHL/MHL
Time Frame: Visit 1 day 1
The difference between masked (if not available unmasked) BC and AC thresholds (unaided), denoted 'air to bone gap', calculated for frequencies 500, 1000, and 2000 Hz for the patients with CHL/MHL within indication on the implanted ear. For bilateral patients, the best ear was selected. Only participants that had complete data for these frequencies were included in the analysis.
Visit 1 day 1
Skin Condition Assessment Around the Abutment
Time Frame: Visit 2, 3 months

Skin condition around the abutment was assessed via Holgers score (scale 0-4).

Holgers 0: No skin reaction Holgers 1: Redness with slight swelling Holgers 2: Redness, moistness, and moderate swelling Holgers 3: Redness, moistness, and moderate swelling with tissue granulation Holgers 4: Profound signs of infection, resulting in removal of the implant

Only participants who had recorded Holgers score in record were analyzed.
