X-linked mixed deafness with congenital fixation of the stapedial footplate and perilymphatic
Differential diagnosis includes OME, perilymphatic
fistula, and BPVC (Baloh & Honrubia).
sup] reported that preexposure by perilymphatic
application of edaravone reduced NIHL in guinea pigs.
Measurements were performed by lowering the double-barreled ion-selective electrode into the fistula of the perilymphatic
sac, using a micromanipulator under visual guidance (OPNI 1, Carl Zeiss, Thornwood, NY).
Diffuse parenchymal (or alveolar septal) amyloidosis is in the differential of perilymphatic
nodularity but has no zonal predilection and is not associated with bilateral mass-like consolidation.
There were multiple, high-risk, histologic features including tumor necrosis, pagetoid spread, perilymphatic
spread, and neurovascular infiltration (Figure 2, A and B).
Beta-2 transferrin assay in clinical management of cerebral spinal fluid and perilymphatic
In our patient, viral culture of the perilymphatic
fluid remained negative while the PCR findings were positive.
Multiple thin-walled cysts in a uniform but perilymphatic
distribution are most commonly present, with or without an associated pneumothorax (Figure 18).
4) Low CSF pressure may induce low perilymphatic
pressure and, in theory, low perilymphatic
pressure may trigger a pressure imbalance, leading to compensatory endolymphatic compartment swelling.
Case of perilymphatic
fistula caused by medially displaced tympanostomy tube.
Pneumolabyrinth and associated pneumocephalus can be seen in head trauma, (1-5) barotrauma, (6) surgical intervention, (7-10) infection, (11) perilymphatic
fistula, (12) and displacement of the footplate.
