Twenty-one patients with unilateral sudden deafness and 16 patients wi
th vestibular neuritis. all with typical clinical history and findings
, were investigated for a possible borrelia-cause. Only one patient, a
patient with vestibular neuritis, had evidence of active borreliosis
in terms of high antibody-titers in CSF, increased cell count and dist
urbed albumin ratio. To gain more knowledge about the etiological role
of Borrelia burgdorferi in patients with hearing and vestibular sympt
oms, it is, despite this sparse finding, motivated to perform Borrelia
testing in patients from tick-frequent areas. A reliable testing incl
udes both serum and CSF analysis.
