Conditions

Conditions

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Collect retrospective audiological and safety results of PMEI implanted subjects. A post-operative minimum and maximum follow-up period was not defined. The mean of the post-operative follow-up period of all patients was calculated.

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

1 second to 99 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study population included MED-EL PMEI implanted patients with a pre-existing condition which made the implantation of a MED-EL PMEI necessary.

Description

• Inclusion Criteria: Implanted with a MED-EL PMEI; initial implantation or revision implantation receiving a MED-EL PMEI

• Exclusion Criteria: None

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.
1

Total Ossicular Replacement Prostheses:

The primary objective for the total ossicular replacement prostheses was to achieve an ABG ≤ 20 dB by at least 25 % of the patients after the PMEI implantation
Device: PMEIs

To evaluate audiological outcomes post-operatively, the air-bone gap (ABG) was assessed.

To evaluate safety of the devices, adverse events were collected.A post-operative minimum and maximum follow-up period was not defined. The mean of the post-operative follow-up period of all patients was calculated. To assess whether implantation of PMEI affected residual hearing pre- and post-operative bone conduction thresholds were evaluated.
2

Partial Ossicular Replacement Prostheses:

The primary objective for the partial ossicular replacement prostheses was to achieve an ABG ≤ 20 dB by at least 53.8 % of the patients after the PMEI implantation.
Device: PMEIs

To evaluate audiological outcomes post-operatively, the air-bone gap (ABG) was assessed.

To evaluate safety of the devices, adverse events were collected.A post-operative minimum and maximum follow-up period was not defined. The mean of the post-operative follow-up period of all patients was calculated. To assess whether implantation of PMEI affected residual hearing pre- and post-operative bone conduction thresholds were evaluated.
3

Stapesplasty Prostheses:

The primary objective for the stapes prostheses was to achieve an ABG ≤ 20 dB by at least 86 % of the patients after the PMEI implantation.
Device: PMEIs

To evaluate audiological outcomes post-operatively, the air-bone gap (ABG) was assessed.

To evaluate safety of the devices, adverse events were collected.A post-operative minimum and maximum follow-up period was not defined. The mean of the post-operative follow-up period of all patients was calculated. To assess whether implantation of PMEI affected residual hearing pre- and post-operative bone conduction thresholds were evaluated.

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
ABG
Time Frame: A post-operative minimum and maximum follow-up period was not defined.
To collect post-operative PTA4 ABG results. It was expected to achieve a post-operative ABG ≤ 20 dB with a PMEI, by at least 25 % of the total ossicular replacement prostheses patients, by at least 53.8 % of the partial ossicular replacement prostheses patients, and by at least 86 % of the stapes prostheses patients.
A post-operative minimum and maximum follow-up period was not defined.

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.

Study Major Dates

Study Start (Actual)

Study Start

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion
