Evaluation of Clinical Outcomes of Ponto Procedures Performed in Settings Outside the Main Operating Room (i.e. Out-of-OR)

May 16, 2025 updated by: Oticon Medical
This study is a combined retro- and prospective, single arm, multicentre investigation designed to follow clinical practice for Ponto-implantations performed out of OR. The overall objective is to investigate the complication rate for procedures performed out-of-OR.

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.

Detailed Description

The study is observational and non interventional and follows clinical practice at participating clinics with the only exception of three questionnaires given to consenting patients after surgery and during follow-up, after loading of the sound processor.

The study is a combined retro- and prospective study. The retrospective part consists of a chart review of patients who have undergone Ponto-implantation out of OR from 2019 and onwards. The prospectively recruited subjects are patients who are planned to undergo Ponto-implantation surgery out-of-OR.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Retrospective group
Data gathered from retrospective chart reviews of patients who have undergone Ponto-implantation in an out-of-OR setting from 2019 and onwards
Device: Ponto implantation
Ponto implantation is a surgical procedure to implant a bone-anchored hearing device, improving hearing by transmitting sound directly to the inner ear through bone conduction.
Prospective group
Patients who have undergone Ponto implantation in an out-of-OR setting and participated in the study by filling out questionnaires.
Device: Ponto implantation
Ponto implantation is a surgical procedure to implant a bone-anchored hearing device, improving hearing by transmitting sound directly to the inner ear through bone conduction.

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
Time Frame
Intraoperative complications at surgery
Time Frame: During the Ponto-implantation surgery
During the Ponto-implantation 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
Assessment of procedure room variables
Time Frame: 12 months after study start
To make an assessment of how procedure rooms that are used for Ponto out-of-OR surgeries look like. Will be measured using the 'Procedure room used for Out-of-OR Ponto-surgery questionnaire'
12 months after study start
To assess surgical parameters
Time Frame: During Ponto-implantation surgery
With this outcome, the aim is to assess the surgical variables present during Ponto out-of-OR surgeries. A series of yes or no questions will be presented in a form to the surgeon regarding the use of anesthesia, sedatives, implants, and abutments of different lengths. The results will be presented in a table.
During Ponto-implantation surgery
Evaluation of patient experience of surgical procedure based on Ponto procedure questionnaire
Time Frame: 5-10 days after Ponto surgery
Score is reported on a scale of 5 steps, were the lowest value (1) is the worst and the highest value is the best (5)
5-10 days after Ponto surgery
To assess postoperative events and complications
Time Frame: From day of surgery, through study completion, an average of 1 year
All postoperative events and complications will be presented in a descriptive table, listing how many were affected by each type of event or complication.
From day of surgery, through study completion, an average of 1 year
To assess rate of implant survival
Time Frame: 3 months after surgery, and through study completion, an average of 1 year.
Implant survival will be assessed at least once, at 3 months. If follow-up data is available, implant survival will be assessed through study completion, an average of 1 year.
3 months after surgery, and through study completion, an average of 1 year.
To assess time from surgery to sound processor loading
Time Frame: Time from surgery to sound processor loading which happens at an average of 3 months after surgery.
Time from surgery to sound processor loading which happens at an average of 3 months after surgery.
To assess sound processor usage time
Time Frame: 3 months after surgery, and through study completion, an average of 1 year.
3 months after surgery, and through study completion, an average of 1 year.
To assess effectiveness of hearing rehabilitation using IOI-HA questionnaire
Time Frame: 3 months after surgery
Will be assessed using the standardised questionnaire International Outcome Inventory for Hearing Aids (IOI-HA) score at 3 months post-surgery. In the questionnaire, each item has five response choices proceeding from the worst outcome to the best outcome (1-5). The score will be presented as mean score with, standard deviation and median for the two groups.
3 months after surgery
To assess patient-reported benefit after BAHS treatment using the questionnaire Glasgow Benefit Inventory (GBI)
Time Frame: 3 months after surgery
Glasgow Benefit Inventory (GBI) benefit scores will be presented for total-, general-, social- and physical scores at 3 months post-surgery. The GBI uses a scale from -100 to +100, where scores above 0 indicate improved quality of life.
3 months after surgery
