Abstract
OBJECTIVE: Our goal was to find whether inreversible function damage of saccule was exist and correlated in Meniere's patients with different audition.
METHOD: Senenty-nine patients with unilateral Meniere's disease, who visited the Dizziness Diagnosis and Treatment Centre of the Second Military Medical University from January to July in 2015 were included. They were grouped as slightly audition damage group (41 cases), mildly-severely audition damage group(38 cases). Meanwhile 20 normal controls underwent the research. The cervical vestibular evoked myogenic potentials were conducted in symptom free period.
RESULT: There was no significant difference of the C-VEMP inducing rate between slightly audition damage group and normal control group. While a statistically difference showed between mildly-severely audition damage group and normal control group or slightly audition damage group. P1, N1 latency had no statistically difference between three groups. The P1-N1 amplitude and asymmetric ratio had no difference between slightly audition damage group and normal control group, but had a statistically difference between mildly-severely audition damage group and slightly audition damage group, normal control group.
CONCLUSION: The function of saccule in Meniere's patients decreased with the aggravation of audition damage.
