Hewing impairment in rheumatoid arthritis has been shown by sever
al studies. Some studies showed the sensorineural nature of hearing loss
denoting inner ear affection while others showed conductive hearing loss
denoting middle ew affection.
The aim of this study was to assess the affection of the Auditory Func
tion in relation to rheumatoid arthritis and its relation to the activity of the
disease. This study was conducted upon two groups: study group and

thritis and normal ew, drum and middle ear by clinical examination, cas
es treated by ototoxic drugs were excluded from the study. The study
group subdivided into active and inactive group and control group includ
ed 26 patients free from rheumatoid and hearing loss.
The study showed 22% 122 ews)from the study group had SNHL and
6% (6 ews) had mixed hearing toss. Conductive deafness not detected in
any case of study groups.
The results ofABR, SISI, tone decay and WDS showed that the leston
most probably occur in cochlea.
The study showed some cases with osstoular loosening and others
with Stiffness. There is no difference Between RF +ve and RF-ve, also ac
tive rheumatoid and inactive regarding to hearing loss.
TTi^ cause of hearing toss lies among 3 causes: ototoxic drugs used in
the treatment of rheumatoid arthritis, alteration of ossicular mechanism |
