About this trial
This is an interventional treatment trial for Bone Conduction Deafness
Eligibility Criteria
Inclusion Criteria:
- 18 years or older.
- Patient indicated for an ear level bone anchored sound processor.
- Healthy bone quality to allow for 4mm implant insertion.
Exclusion Criteria:
- Intraoperative switch to an alternative surgical technique
- Patients undergoing re-implantation (on the side being included in the study)
- Previous participation in the C47 study.
- Inability to participate in follow-up.
- Psychiatric disease in the medical history.
- Mental disability.
- Presumed doubt, for any reason, that the patient will be able to show up on all follow-ups.
- Diseases or treatments known to compromise the bone quality at the implant site, e.g. radiotherapy, osteoporosis, diabetes mellitus.
- Patients with natural skin height of >12mm (as there will be additional skin reduction needed)

Minimally Invasive Ponto Surgery
Arm Description
Surgical method for installation of a bone anchored hearing system for hearing rehabilitation
Outcomes
Primary Outcome Measures
Numbness (sensibility) around the implant
Total numbness around the implant will be assessed as a combination of gnostic and vital sensibility.
Secondary Outcome Measures
Length of surgery
Compare the surgical time between test (this investigation) and control group (previous investigation, C47).
Unplanned visits
Investigate and compare the number of unplanned visits, including unplanned surgical procedures and other treatments for the test (this investigation) and control group (previous investigation, C47).
Adverse skin reactions
Investigate and compare the rate of adverse skin reactions using the Holgers Scale.
Adverse skin reactions
Investigate and compare the rate of adverse skin reactions using the IPS scale.
Pain perception by patient
Investigate and compare pain using a visual analogue scale 0-10
Implant survivability
Investigate and compare implant survivability in terms of reported implant loss.
Implant stability as measured with resonance frequency analysis, RFA.
Investigate and compare implant stability.
Implant stability is monitored by measuring the implant stability quotient when following up on patients. Stability will be reported as implant stability quotient (ISQ).
Surgical wound healing time
Investigate and compare healing time after surgery.
Follow-up visits after surgery will assess the healing of wound. This will be a yes/no assessment to be answered by the attending physician. The investigators will also evaluate skin reactions and record any medications that were given to aid in skin healing.
Wound dehiscence
Investigate wound dehiscence size after surgery.
Quality of Life Assessment
Investigate and compare subjective benefit as measured by SSQ questionnaire.
Quality of Life Assessment
Investigate and compare subjective benefit as measured by YORK questionnaire.
Quality of Life Assessment
Investigate and compare subjective benefit as measured by APHAB questionnaire.
Quality of Life Assessment
Investigate and compare subjective benefit as measured by GBI questionnaire.
Quality of Life Assessment
Investigate and compare subjective benefit as measured by GHSI questionnaire.
