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
EXPERIMENTALIntraoperative palpation of the ossicles using the PalpEar device, to measure mobility of the ossicle chain.
Interventions
Palpation of the middle-ear ossicles using the PalpEar device, to measure mobility of the ossicle chain
Eligibility Criteria
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.
