Trial summary

In children undergoing tonsillectomy ± adenoidectomy without eustachian dysfunction, the objective is to control tubal functions with tympanometry utilising probes at 226 Hz and 1000 Hz, as well as measuring the ipsilateral and contralateral acoustic reflexes with a 226 Hz probe.

About this study

Official title: Evaluation of Eustachian Tube Function With 226 and 1000 Hz Probes in Children Undergoing Tonsillectomy ± Adenoidectomy Without Tubal Dysfunction

In children undergoing tonsillectomy ± adenoidectomy without eustachian dysfunction, the objective is to control tubal functions with tympanometry utilising probes at 226 Hz and 1000 Hz, as well as measuring the ipsilateral and contralateral acoustic reflexes with a 226 Hz probe. An eustachian function test with a 226 Hz probe (automatic Williams test) and play audiometry are to be conducted on young children, while pure tone audiometry is to be conducted on older children, in the preoperative period, on the first day after surgery and in the second week after surgery. The primary objective is to ascertain whether the tubal functions, which are hypothesised to be impaired on the first day, return at the latest in the second week, with all tests evaluating the eustachian tube both directly and indirectly. The secondary objective is to determine whether this recovery occurs earlier with the 226 Hz probe or the 1000 Hz probe.

What is being measured

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

  1. Evaluation the functionality of the eustachian tube with odiometric tests

    Evaluation the functionality of the eustachian tube, which was presumed to be compromised on the initial post-adenotonsillectomy day, and ascertainment whether it had recuperated by the second week. Tympanometry with 226 and 1000 Hz probes, eustachian function test with 226 Hz probe, ipsi and contralateral acoustic reflexes with 226 Hz probe and pure tone-play audiometry were performed in all patients one day before the operation. All tests were repeated on postoperative day 1 before the patient was discharged. All tests were repeated at the 2nd postoperative week.

    Measured: 14 days

Secondary outcomes (1)
  1. Evaluation the functionality of the eustachian tube with tympanometry the 226 Hz and 1000 Hz probes

    It was investigated which of the 226 Hz and 1000 Hz probes used in these tests detected earlier recovery findings.

    Measured: 21 days

Questions about this trial

What is this clinical trial studying?

An observational study of Tonsillar Hypertrophy and Eustachian Tube Dysfunction, run by Sumeyra DOLUOGLU at 1 site in Turkey (Türkiye).

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 5 inclusion and 5 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: finished, as of the sponsor's last update on 15 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Evaluation the functionality of the eustachian tube with odiometric tests (time frame: 14 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06577051, which also lists 1 linked publication.

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 15 Apr 2025.
