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

结局指标
主要结局
Measurement of the ossicle mobility through the palpation force
时间窗: 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.
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.
次要结局
- 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.)
