Objectives: The aim of this study is to investigate the possible
correlation between tinnitus and hearing level and the effect of surgery
on tinnitus in otosclerosis patients with tinnitus.
Methods: In this study, 55 patients (59 ears) operated for
otosclerosis with tinnitus between December 1998 and April 2006 were
retrospectively reviewed. Preoperative and postoperative mean air and
bone conduction thresholds, mean air bone gaps and speech discrimination
scores in postoperative tinnitus ceased and tinnitus no change groups
were evaluated.
Results: Tinnitus was ceased in 30 ears and no change was
detected in 29 ears following surgery on the postoperative third month
control. In tinnitus ceased group, preoperative mean bone conduction
level was 21±2 dB, mean air conduction level was 56±2 dB, mean air-bone
gap was 34±1 dB and speech discrimination score was 98±1%. In tinnitus
no change group, these results were 33±3 dB, 69±3 dB, 36±2 dB and 87±3%
respectively. Similarly, in tinnitus ceased group postoperative mean
bone conduction threshold was 9±1 dB, mean air conduction threshold was
23±1 dB, mean air-bone gap was 14±1 dB and speech discrimination score
was 100%. In tinnitus no change group, these results were 24±3 dB, 41±4
dB, 17±2 and 93±2% respectively. Besides, the postoperative air
conduction gain in tinnitus ceased group was 33±2 dB and it was 28±3 dB
in tinnitus no change group.
Conclusion:
In patients with hearing loss and tinnitus due to otosclerosis, tinnitus
was ceased among half of the patients after stapedotomy procedure. It
was assured that there is a relationship between tinnitus course and
hearing levels of the patients. |
