The prevalence of aural symptoms in 100 patients with
temporomandibular disorder (TMD) were investigated and
compared with control group of 100 subjects without clinical
manifestation of TMD. The relationship between otologic symptoms
and severity of TMD signs was also evaluated.
Examination of temporomandibular joint (TMJ) included
maximum mouth opening, clicking, crepitation, locking, luxation,
deviation of midline, masticatory muscle tenderness, and
TMJ tenderness. All patients of the two groups were questioned
about feeling of ear complaints, including otalgia, tinnitus,
and hearing loss.
It was found that 48% of TMD patients complained of
one or more aural symptoms compared with 13% of the controls.
There was a highly significant difference between the
two groups (p<0.01).
The prevalences of otalgia, tinnitus, and hearing loss in
TMD patients were 36%, 27%, and 4% respectively. While in
the control group the prevalences were otalgia 6%, tinnitus
10%, and hearing loss 1%. There were highly significant differences
between the two groups regarding otalgia and tinnitus
(p<0.01).
The evaluation of the relationship between aural symptoms
and TMD signs, yielded a significant positive correlation
between otalgia with clicking, number of tender muscles,
and TMJ tenderness. While it reversibly correlated with mouth
opening. Tinnitus was found to be positively correlated
with clicking and number of tender muscles.
From the results of this research, dentist and otolaryngologist
must act as a team in recognizing and diagnosing
TMD and the otolaryngologists should refer patients with otalgic
complaint without apparent ear diseases to a specialist in
TMD for further evaluation
