Abstract
The auditory post-auricular responses (PAR) were recorded in 28 children aged 0 to 12 with unilateral microtia, and the influence of the post-auricular muscle (PAM) development on the responses were investigated. Responses obtained from the sides of microtic ears and normal ears showed no significant differences in the wave form, threshold, latency, nor in amplitude. Muscle volume of the PAM did not affect the amplitude of the PAR.
