Objective:
The aim of this study is to evaluate any possible effects of chronic
otitis media (COM), with or without accompanying cholesteatoma, on bone
conduction thresholds (BCT).
Methods:
A total of 112 cases who underwent surgery for unilateral COM between 2006 and
2014 were enrolled in the study. Eighty cases had no cholesteatoma (Group 1).
Thirty-two cases did have cholesteatoma (Group 2). Prior to surgery, the
temporal bone was evaluated radiologically by use of high resolution computed
tomography. The presence of a clinically and radiologically normal
contralateral ear was the principal selection criterion for the cases. BCT at
0.5, 1, 2, 4 kHz and their averages were evaluated with pure tone audiogram
(PTA) and the normal and diseased ears in each group were compared. This
comparison was also made between the diseased ears in Groups 1 and 2.
Results:
There was a statistically significant difference observed between the
mean BCT scores obtained by PTA for the normal/diseased ears in Group 1
(9.78±0.98/17.34±1.71 dB) and in Group 2 (9.10±0.99/17.58±2.59 dB). This
statistically significant difference was observed for each of the four
different frequencies (p<0.0001). However, there was no statistically
significant difference observed between the mean BCT scores obtained by PTA for
the diseased ears in Groups 1 and 2 (17.34±1.71/17.58±2.59 dB). Similarly, in
the comparison between the diseased ears, the differences of BCT at all four
different frequencies (0.5, 1, 2, 4 kHz) lacked statistical significance
(p>0.05).
Conclusion:
As
a result of this study, we can say that COM may lead to sensorineural hearing
loss. However, we observed that the presence of cholesteatoma does not exert an
additional negative effect on cochlear function.
