Changes in caloric responses after temporal bone surgery with posterior tympanotomy

The insertion of electrodes during CI did some damages to vestibular peripheral function and reduced both hot and cold caloric responses according to the results of CI. However, the procedure during posterior tympanotomy could also decrease caloric responses especially in cold stimulation according to the results of FND. Therefore, we should consider the effect of structural change in temporal bone on the thermal transmission in case of evaluation of vestibular peripheral function by using caloric stimulation test.
