Outcome Measures

Primary Outcomes (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.

    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)

  • Difference between normal and impaired ossicular chains

    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.

Study Arms (1)

PalpEar

EXPERIMENTAL

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.

You may not qualify if:

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