Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Numbness (sensibility) around the implant
Time Frame: 6 months post surgery
Total numbness around the implant will be assessed as a combination of gnostic and vital sensibility.
6 months post surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Length of surgery
Time Frame: At surgery
Compare the surgical time between test (this investigation) and control group (previous investigation, C47).
At surgery
Unplanned visits
Time Frame: 36 months
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).
36 months
Adverse skin reactions
Time Frame: 36 months
Investigate and compare the rate of adverse skin reactions using the Holgers Scale.
36 months
Adverse skin reactions
Time Frame: 36 months
Investigate and compare the rate of adverse skin reactions using the IPS scale.
36 months
Pain perception by patient
Time Frame: 36 months
Investigate and compare pain using a visual analogue scale 0-10
36 months
Implant survivability
Time Frame: 36 months
Investigate and compare implant survivability in terms of reported implant loss.
36 months
Implant stability as measured with resonance frequency analysis, RFA.
Time Frame: 36 months

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).
36 months
Surgical wound healing time
Time Frame: 36 months

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.
36 months
Wound dehiscence
Time Frame: 36 months
Investigate wound dehiscence size after surgery.
36 months
Quality of Life Assessment
Time Frame: 36 months
Investigate and compare subjective benefit as measured by SSQ questionnaire.
36 months
Quality of Life Assessment
Time Frame: 36 months
Investigate and compare subjective benefit as measured by YORK questionnaire.
36 months
Quality of Life Assessment
Time Frame: 36 months
Investigate and compare subjective benefit as measured by APHAB questionnaire.
36 months
Quality of Life Assessment
Time Frame: 36 months
Investigate and compare subjective benefit as measured by GBI questionnaire.
