Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adult subjects
* Normally scheduled for middle-ear or internal-ear surgery as a result of an ear disease and for whom a routine assessment of the mobility of the ossicle chain is in order.

The targeted subject population consists of patients undergoing stapedotomy for otosclerosis and subjects with a normal ossicular chain who are subject to the placement of a cochlear implant to treat hearing loss.

Exclusion Criteria

* Children
* Subjects in whom the ossicle chain is missing or incomplete
* Missing informed consent form
* Incapacitated subjects or subjects with impaired judgment capability.
Minimum Eligible Age
