About this study

Official title: Messung Der Beweglichkeit Der Gehörknöchelchenkette während Einer Ohroperation. ("Objective Measurements of Ossicular Chain Mobility Using a Palpating Instrument Intraoperatively")

Feasibility of the objective measurement of the ossicular chain mobility, by using a force-measuring device based on a fiber optics sensors (PalpEar).

Read the detailed description

The aim of this study was to develop and test a palpating instrument, which enables the experienced and occasional otologic surgeon to record force in three dimensions during his standard palpation of each ossicle at surgery and al-lows correlation of his subjective impression with objective measurement results. The first task was to incorporate force sensing capability into a standard 45° angulated 2.5 mm hook, which is commonly used to palpate, disconnect and luxate ossicles during middle ear surgery.

What is being measured

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

  1. Measurement of the ossicle mobility through the palpation force

    The palpation forces needed to move the middle-ear ossicles out from their resting position will be measured through a force sensing device. The measured palpation forces are measured in equivalent gram-force [gF]. The primary outcome of the study is to demonstrate if a relation can be established between the subjective feeling of the surgeon and an objective measurement of the palpation force.

    Measured: 1 day. The measurements are performed during day 1, in parallel with the underlying surgery, and therefore assessed within the time frame of 1 day.

Secondary outcomes (1)
  1. Difference between normal and impaired ossicular chains

    A comparison between ossicular chains judged as "normal" by the surgeon and impaired ossicular chains will be performed, to assess if a significant difference can be extracted from the measurement of the palpation force. This would help in a future diagnosis assisted by a force sensing device.

    Measured: 1 day. The measurements are performed during day 1, in parallel with the underlying surgery, and therefore assessed within the time frame of 1 day.

Questions about this trial

What is this clinical trial studying?

A study testing PalpEar in people with Disorder of Middle Ear and Otosclerosis of Middle Ear, run by Sensoptic SA.

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 4 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 18 Sep 2015. 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?

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?

Measurement of the ossicle mobility through the palpation force (time frame: 1 day. The measurements are performed during day 1, in parallel with the underlying surgery, and therefore assessed within the time frame of 1 day.). 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 NCT02554422, which also lists 10 linked publications.

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 18 Sep 2015; AzTrials last refreshed its copy on 6 Nov 2026.
