説明

Transtympanic electric promontory stimulation (EPS) was first performed by House & Brackmann for the purpose of differentiating between sensory and neural type deafness. There are few reports dealing with EPS in neural deafness. This paper focuses on the accuracy of EPS, with the use of a promontory stimulator (Nucleus Co.), in patients with neural deafess. EPS was used to test 18 ears of 17 patients aged 23 to 63 years (mean 46.0 years). The diagnoses were acoustic neuroma (14 patients) and other cerebellopontine (CP) angle tumors (3 patients). A positive response to EPS was noted in 2 of the acoustic neuroma patients (22%), before surgery and hearing with good speech discrimination was preserved in these patients. A positive response was found in 2 of 2 CP angle tumor patients (100%) before the operation. Of the 7 patients tested with EPS after surgery, all showed a negative response. These results suggest that pressure on the acoustic nerve by the tumors was most closely correlated with the response to EPS.
