Abstract
ABSTRACT
Introduction: Cochlear implantation (CI ) is a standard of care for the patients with moderate to severe sensorineural
hearing loss in the past more than 20 years. Postoperative vertigo it’s one of the well-known complications and
has a considerable impact of patient life. Children really suffer from this complication, usually in milder form
and almost never long-term vertigo. The aim of presenting this case is to pint out the need to examine the
vestibular function in each patient preoperatively. Case report: A 9-year-old child, with recurrent episodes of
vertigo appearing for the first time 6 years after the implantation. Vestibular assessment function was done with
caloric irrigation bitermal test that showed asymmetry between two labyrinths. Romberg showed deviation on
the right side. Haed impuls test was positive on the right side and Dix –Hallpike’s maneuver test was negative.
There was no neurological signs and symptoms. Every next episode of vertigo was milder than the previous
one and he well responded to standard vestibular therapy with Beathistine or Sulpiride. Vertigo did not affect
implant performance,
Conclusion: Patients which are candidates for CI it’s necessary to be informed about possibility and quality of postoperative vertigo. Implementing a protocol for preoperatively evaluation of the vestibular function of specially
designed questionnaires and objective tests for assessment of the vestibular function should be standard procedure
for each patient who is candidate for CI.
