The goal of this single center, prospective study is to investigate the survival of the Ponto Wide Implant at least 10 years after implantation.
Secondary objectives are:
During a check-up of the implant at the outpatient clinic, the skin around the implant will be assessed, the stability of the implant will be measured, and the patient will be asked to complete two questionnaires.
Patients who participated in the previous studies concerning the Ponto Wide implant from Oticon (3 years after implantation) will be approached. If consent is given, they will be added to the database of the already completed studies, and new data will be stored in the same database. The patients were already pseudonymized in the previous studies, and the database is secured with a code that is only accessible to individuals directly involved in the research

The reason for each implant loss.
| This will be examined during the period from November 2024 to March 2025 |

| Implant stability Quotient (ISQ) measured using Osstell | ISQ (implant Stability Quotient) is a measurement scale for use with the Resonance Frequency Analysis (RFA) method of determining implant stability. The measurement is made using the Osstell Mentor equipment (Osstell, Sweden) with SmartPegs. ISQ values range from 1 to 100, the higher the score the higher the stability. The highest and lowest score obtained from perpendicular measurements will be registered. | It will be assessed during the clinic visit between November 2024 and March 2025. |
| Skin complication | Skin complication rates at >10-year follow-up are assessed using both the Holgers classification and the IPS-score. Both classification systems are standardized scales to clinically assess the skin condition around the implant. | It will be assessed during the clinic visit between November 2024 and March 2025. |
| Sound processor use | Average sound processor usage (hours per day; days/week) >10 years post-surgery. | It will be assessed during the clinic visit between November 2024 and March 2025. |
| Glasgow Benefit Inventory (GBI) | The GBI questionnaire is used to evaluate the quality of life after a medical intervention. The questionnaire consists of 18 items corresponding to different aspects of the patient's well-being: quality of life, self-confidence, support, general health, and social involvement. The scoring ranges from 1 to 5, indicating that a higher score means the statement is more applicable to the patient after the intervention. | It will be assessed during the clinic visit between November 2024 and March 2025. |
| International Outcome Inventory for Hearing Aids (IOI-HA) | The IOI-HA questionnaire is a seven-item tool designed to be broadly applicable in evaluating the effectiveness of hearing aid treatments. These questions provide insight into how satisfied patients are with their hearing aids. Each statement offers five possible responses on an ascending scale, indicating whether the answer is more or less applicable to the statement. | It will be assessed during the clinic visit between November 2024 and March 2025. |
