Abstract
: In Meniere’s disease, distention of the structures filled with
endolymph occurs. The cochlear duct, saccule, utricle or ampulla contain
endolymph, and a change in volume of these structures are tightly
correlated with the symptoms of Meniere’s disease (MD).
It is known that episodic vertigo, fluctuating sensorineural hearing loss,
tinnitus, and/or aural fullness are the four typical clinical symptoms of this
disease. However, the clinical features that the patient presents are always
quite atypical, especially in an early stage.
Objective: to asses the role of MRI in diagnosis of Meniere’s disease
Methods: 20 adult patients diagnosed as Meniere’s disease (11 males and
9 females) were examined by c-VEMP and MRI.
Results: the affected ear showed a significant delay in latency of P13&N23
in cVEMP and a significantly decreased in N1-P1amplitude compared to
the non-affected ears.
MRI results: it was divided into Quantitative and Qualitative:
Quantitative mothod:
6 out of 20 cases (30%) were positive for Meniere and 4 of them were
positive with other pathologies
14 out of 20 cases (70%) were Negative for Meniere and 4 of them were
negative with other pathologies.
Other pathologies were either high arched jugular bulb or AICA vascular
looping which causes Tinnitus in the affected side.
Qualitative mothod:
According to SURI grading (sacculo utricular ratio index) Attye et al.,
(2017) it was done on 7 of the 20 cases.
Results were found
6 positive cases (85.7%) were graded as SURI Grade 1
1 out of 14 negative cases (14.3%) were graded SURI Grade 0
The specificity and sensitivity of the SURI were 100% and 30%
respectively in our results
Conclusions: cVEMP is a reliable objective method in evaluating the
saccular dysfunction in MD patients. For MRI it states the degree of
saccular morphology, cochlear hydrops and vestibular hydrops.
MRI is a reliable objective method in confirming the diagnosis of
Meniere`s disease as it states the degree of saccular morphology
