Objective : The purpose of this study was to investigate whether auditory steady-state responses would reveal characteristics indicative of acoustic neuroma in patients. Methods : Subjects were 42 unilateral acoustic neuroma patients with an average age of 55.0 (±13.6) years. The control group consisted of 19 idiopathic sensorineural hearing loss patients with an average age of 42.3 years (±18.8 years). Carrier frequencies used to obtain auditory steady-state response were 500, 1,000, 2,000 and 4,000 Hz, respectively. The measured auditory steady-state responses thresholds were compared with hearing levels of the pure tone audiogram. Results : The auditory steady-state response threshold was somewhat greater (6 to 12 dB) than the pure-tone threshold that has been reported. Even higher thresholds were found in the acoustic neuroma group. In fact, when the subtracted values obtained by auditory steady-state responses threshold minus pure tone audiogram threshold of each frequency in each case were compared between the two groups, the acoustic neuroma group showed significantly greater values in all frequency regions. On the other hand, no differences were found in the values between the control and intact ear side. Conclusion : The presence of acoustic neuroma may lower the auditory steady-state responses threshold. This might reflect that the tumor could jitter in creating a auditory steady-state responses. |
