About this study

Official title: Evaluation of Long-Term Results of Bone Cement Application in Stapes Surgery and Factors Effective on Results in Stapes Surgery

Considering the long-term results of otosclerosis surgery performed in our clinic, it was observed that in addition to the improvement in air conduction hearing, which indicates conductive hearing, which is the main success of the surgery, there was also an improvement in bone conduction hearing, which indicates sensorineural hearing, in patients using bone cement.

Our study aimed to examine the effect of bone cement use in otosclerosis surgery on long-term hearing thresholds and bone conduction.

Read the detailed description

A retrospective review was conducted on records of patients who underwent stapes surgery between 2012 and 2020.

Comprehensive records were selected, and patients were summoned for clinic visits for thorough examinations. Evaluation encompassed the average of air and bone conduction at 500, 1000, 2000, and 4000 Hz. A procedure-specific 16-item questionnaire and the Glasgow Benefit Inventory (GBI) were used for perceived benefit and effective factors.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Use of bone cement in otosclerosis surgeryProcedure or surgery

    Surgical technique; It involves separating the sclerosed stapes from the oval window and incus under an endoscope or microscope and replacing it with a Teflon piston, which is a middle ear prosthesis. In this way, a new connection between the incus and the oval window ensures the transmission of sound to the inner ear. Bone cement has long been used in primary and revision ossiculoplasty, including stapedotomy of the middle ear. During stapedotomy, the part of the Teflon piston that places the teflon piston on the incus is fixed with bone cement, aiming to keep the prosthesis in place for a long time and prophylactic treatment of incus necrosis.

What is being measured

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

  1. Incidence of improvement of conductive hearing loss in patients using bone cement

    Changes in conductive hearing loss will be examined using pure tone audiometry testing.

    Measured: This retrospective cohort study with prospective follow-up included patients who underwent stapes surgery for conductive hearing loss between 2012 and 2022

Secondary outcomes (3)
  1. Incidence of decrease in bone conduction hearing threshold in patients using bone cement

    The change in sensorineural hearing threshold will be examined using pure tone audiometry test.

    Measured: This retrospective cohort study with prospective follow-up included patients who underwent stapes surgery for conductive hearing loss between 2012 and 2022

  2. Glasgow Benefit inventory

    The GBI is an 18-item, validated instrument designed specifically to assess patient-perceived benefits following otolaryngologic interventions. It utilizes a five-point Likert scale. The score is changing between -100(worst) and +100(best). Total scores interpreted as follows: >50 indicates significant benefit, 10-50 indicates moderate benefit, and <10 denotes no perceived benefit.

    Measured: This retrospective cohort study with prospective follow-up included patients who underwent stapes surgery for conductive hearing loss between 2012 and 2022

  3. Postoperative questinarie

    16 items stapedotomy specific questions

    Measured: This retrospective cohort study with prospective follow-up included patients who underwent stapes surgery for conductive hearing loss between 2012 and 2022

Questions about this trial

What is this clinical trial studying?

An observational study of Otosclerosis, run by Pamukkale University 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 1 inclusion and 1 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 14 Jul 2026. 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?

Incidence of improvement of conductive hearing loss in patients using bone cement (time frame: This retrospective cohort study with prospective follow-up included patients who underwent stapes surgery for conductive hearing loss between 2012 and 2022). 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 14 Jul 2026.
