Trial summary

The goal of this observational study is to measure the effect of hyperbaric oxygen therapy on middle ear pressure in order to predict the risk factors for middle ear barotrauma also, to assess its effects on hearing functions of the inner ear in participant population. Read more about this study

About this study

The goal of this observational study is to measure the effect of hyperbaric oxygen therapy on middle ear pressure in order to predict the risk factors for middle ear barotrauma also, to assess its effects on hearing functions of the inner ear in participant population. The main questions aim to answer are:

  • Is there a change in middle ear pressure before and after exposure to hyperbaric oxygen therapy ?
  • Is there a change in hearing threshold level before and after exposure to hyperbaric oxygen therapy ? The middle ear pressure, eustachian tube functions and the hearing threshold of the participants will be assessed immediately before the fist session and within one hour after the first and tenth sessions.
Read the detailed description

Fifty four patients already treated by hyperbaric oxygen therapy recruited from hyperbaric oxygen therapy center of Assiut university hospitals. Otoscopic examination for all patients must be done before and after the session , assessment of middle ear pressure and the state of the eustachian tube through doing eustachian tube function tests (Valsalva and Toynbee tests for ears with intact tympanic membrane and modified inflation - deflation tests for ears with perforated tympanic membrane) by tympanometry for all patients before and after the first session of hjyperbaric oxygen therapy and after completion of the tenth session. Assessment of the hearing threshold level of the patients immediately before the first session and after the tenth session of hyperbaric oxygen therapy through doing pure tone audiometry ( air conduction and bone conduction audiometry) and speech audiometry to assess the speech discrimination score for the patients

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Measuring the changes of the middle ear pressure after exposure to hyperbaric oxygen therapy

    Tympanometric assessment of the middle ear pressure and eustachian tube functions

    Measured: Immediately before exposure to the first session of hyperbaric oxygen therapy and within one hour after exposure to the first and tenth session of hyperbaric oxygen therapy.

Questions about this trial

What is this clinical trial studying?

An observational study of Middle Ear Barotrauma, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measuring the changes of the middle ear pressure after exposure to hyperbaric oxygen therapy (time frame: Immediately before exposure to the first session of hyperbaric oxygen therapy and within one hour after exposure to the first and tenth session of hyperbaric oxygen therapy.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jan 2024.
