For investigation of changes in auditory function in animals requiring surgery through the middleear, a method for bone conduction auditory brainstem responses (ABR) was developed. Results wereas follows;
1. Bone conduction stimulation could be used for auditory brainstem responses in chronic experimentalanimal models of the cat.
2. Bone conduction ABRs were stable for6weeks at most.
3. Bone conduction ABRs were stable with changes in bone oscillator positions as large as 1.0cm.
4. This study might not clarify the possible pseudo-bone conduction ABR changes due to middleear impedance changes.
5. Bone conduction ABR might be useful in the cat for evaluating auditory function central tothe middle ear.
