Objective assessment of vertigo causing perilymphatic fistula in cochlear implantees by cochlin-tomoprotein (CTP)
Objective:
A well-known and frequently reported complication after cochlear implantation is the appearance of postoperative vertigo symptoms. Perilymphatic fistula (PLF) is a known cause for hearing loss and vertigo. Cochlin-tomoprotein (CTP) is a cochlear specific protein acting as a marker for PLF. Aim of the present study was to observe, if the postoperatively new occurence of vertigo is caused by a perilymphatic fistula evidenced by CTP marker.
Methods:
In a prospective analysis 12 cochlear implant patients with the postoperatively new occurence ofvertigo underwent a transtympanallyrevison/resealing surgery. In all patients middle ear fluid was captured and analysed for CTP.
Results:
In 5 out of 12 patients a positive CTP result was found indicating a PLF. Positive PLF finding did not correlate with the intraoperative visual assumption of a leak. The procedure solves in most of the cases the vertigo problem.
Conclusion:
Our present finding demonstrates that objectively an insufficent sealing causing perilymphatic fistula occurs in cases of newly postoperative vertigo after cochlea implantation.
