July 30, 2024 updated by: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

The Brain Network Mechanism and Outcome After Surgical Intervention of Conductive Hearing Loss Accompanied by Tinnitus.

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.

Detailed Description

This study explores the brain region activation and remodeling of poor connections of brain regions in the postoperative outcomes of conductive hearing loss patients with tinnitus by comparing pre - and post-operative audiological assessment, tinnitus assessment and EEG data. Including audiological assessment (pure tone audiometry, speech test), tinnitus assessment (tinnitus matching, tinnitus handicap inventory, tinnitus function index, visual analogue scale)and non-invasive brain imaging assessment (EEG, fNIRS).

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

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • aged between 18 and 60 years;
  • diagnosed with conductive hearing loss with tinnitus;
  • treated with surgery;
  • able to cooperate with all Chinese version evaluation;
  • right-handed.

Exclusion Criteria:

  • Pure tone audiometry indicates that the average pure tone hearing threshold (500Hz, 1kHz, 2kHz, 4kHz) is > 91dB HL;

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
pure tone audiometry
Time Frame: 3-7 days before surgery, 1-12 months after surgery
The air- conducted threshold, bone-conducted threshold and air- bone gap of each frequency of pure tone audiometry were used to compare pre - and post-operative hearing level.
3-7 days before surgery, 1-12 months after surgery
speech test
Time Frame: 3-7 days before surgery, 1-12 months after surgery
Speech audiometry was mainly used to analyze the speech recognition rate of patients before and after surgery
3-7 days before surgery, 1-12 months after surgery
EEG activation
Time Frame: 3-7 days before surgery, 1-12 months after surgery
EEG signals were used to explore the activation of brain regions and remodeling of poor connections in the postoperative outcomes of conductive hearing loss patients accompanied by with tinnitus. Power spectral density calculation, traceability analysis, functional connection, microstate, clustering coefficient, feature path length, feature path intermediation, and isocompatibility coefficient were collected and then analyzed.
3-7 days before surgery, 1-12 months after surgery
tinnitus handicap inventory scores
Time Frame: 3-7 days before surgery, 1-12 months after surgery
The total score of the THI scale and the scores of the three subscales(functional, emotional, and catastrophic) were collected before and after surgery for data analysis.
3-7 days before surgery, 1-12 months after 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
tinnitus function index scores
Time Frame: 3-7 days before surgery, 1-12 months after surgery
The total score of the TFI scale were collected before and after surgery for data analysis.
3-7 days before surgery, 1-12 months after surgery
visual analogue scale
Time Frame: 3-7 days before surgery, 1-12 months after surgery
The total score of the VAS were collected before and after surgery for data analysis. VAS scale 0-10. A score of 0 means that tinnitus has no impact on daily life, and a score of 10 means that tinnitus has an intolerable, fatal level of impact on daily life.
3-7 days before surgery, 1-12 months after surgery
fNIRS activation
Time Frame: 3-7 days before surgery, 1-12 months after surgery
fNIRS signals were used to explore the activation of brain regions and remodeling of poor connections in the postoperative outcomes of conductive hearing loss patients accompanied by with tinnitus. Power spectral density calculation, traceability analysis, functional connection, microstate, clustering coefficient, feature path length, feature path intermediation, and isocompatibility coefficient were collected and then analyzed.
3-7 days before surgery, 1-12 months after surgery
