The fundamental problem was the sampling of perilymph. Single samples from the round window, oval window, and basal turn or sequential sampling from the apical region were attempted (4-6).
To ensure that the vibration source in this study is on the BM, we drained the perilymph at the opened portion of the scala tympani and then maintained the fluid at a very low level (~30 [micro]m) with a cotton wick.
Preoperative computed tomography may fail to detect patients at risk for perilymph gusher.
In vitro induction and differentiation of newborn guinea pig hippocampus neural stem cells into cells resembling inner hair cells, using artificial perilymph. J.
When performing cochleostomy, one must remember that the bone covering the basal turn of the cochlea is very thin and may easily be destroyed, possibly causing a perilymph gusher.
However, since the cantilever is an open structure, it cannot contain the liquid (perilymph) like the BM of the actual cochlea.
[14] reported distribution of an ionic marker, trimethylphenylammonium (TMPA), in the cochlea after intracochlear injection or application to the round window niche based on direct monitoring using a TMPA selective electrode or sequential collection of perilymph. Atotalof65% of TMPA entered through the RWM while 35% entered the vestibule in the vicinity of the stapes.
The least invasive confirmatory tests for CSF rhinorrhea are the presence of either beta-2 transferrin or beta-trace protein in the nasal discharge, which are sensitive and specific for CSF and perilymph fluids [10, 11].
The middle ear system with its smallest bones and articulations is responsible for catching noise energy and transforming it to perilymph pressure changes in the cochlea.
Perilymph fistula is a leakage of inner ear fluid into the middle ear which causes unsteadiness along with dizziness and nausea.
[28-30] When ATP and its analogs were applied to the cochlear perilymph, reductions were observed in OAE amplitudes and auditory nerve compound action potentials.
