Evaluation of the Ponto Bone Anchored Hearing System in a Pediatric Atresia Population

October 29, 2024 updated by: Oticon Medical
The purpose of this study is to in a proactive manner collect high quality data from a pediatric patients who have undergone a bone anchored hearing solution, using the Ponto BHX implant, in clinical practice. This to further increase the knowledge of using the system.

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.

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.

Treatment
Bone Anchored Hearing surgery using a BHX implant manufactured by Oticon Medical
Device: Bone Achored Hearing surgery
This is a observational study of pediatric patients undergoing bone anchored hearing surgery. The collected data will be used to assess the implant stability development of the Ponto BHX implant during up tp 24 months after implantation in a pediatric population undergoing bone anchored hearing surgery.

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
Stability 12 months
Time Frame: 12 months post surgery
The development of implant stability during the first 12 months after implantation; as measured by difference in mean of (Implant Stability Quotient) ISQ low 12 months compared to surgery.
12 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.
