The objective of this study was to determine whether the audiometric findings of migraine-associated dizziness could be used to better distinguish migraine-associated dizziness from Ménière’s disease.
A retrospective chart review.
Tertiary, otology/neurotology practice.
Two groups of patients were studied, a migraine-associated dizziness and a Ménière’s disease group. There were 76 and 34 patients in the migraine-associated dizziness and Ménière’s disease groups, respectively.
Initial and follow-up pure-tone average and low-frequency pure-tone average were recorded for both groups. Independent samples t tests were used to test for mean differences in pure-tone average and low-frequency pure-tone average.
Pure-tone average and low-frequency pure-tone average were significantly worse for patients in the Ménière’s disease group at both the initial and follow-up assessments. Three patients in the migraine-associated dizziness group had an elevated pure-tone average (≥26 dB) and/or low-frequency pure-tone average at initial and/or follow-up assessment. The remaining 73 migraine-associated dizziness patients had normal hearing. In the Ménière’s disease group, only two patients had a normal pure-tone average and low-frequency pure-tone average at both initial and follow-up evaluations. The hearing difference between the two groups was significant even when controlling for age and duration of dizziness symptoms.
Audiometric findings of patients with migraine-associated dizziness are most often normal. Unlike Ménière’s disease, the sensorineural hearing loss in migraine-associated dizziness rarely progresses. These audiometric findings may help to distinguish migraine-associated dizziness from Ménière’s disease when diagnostic ambiguity exists between these two diagnoses.
