The effect of the development of postauricular muscles on the postauricular myogenic response (PAR) was investigated in normal children and children with microtia. There were no differences between the PAR of normal children and that of the intact ear of children with microtia. The PAR obtained from the normal and microtic sides of children with unilateral microtia showed no significant differences as regards waveform, latency, threshold, or amplitude. Our findings suggest that the development of the postauricular muscle does not affect the PAR, and it seems difficult to explain the large individual variations in the PAR by intersubjective differences in muscle development.
研究了正常儿童和小耳畸形儿童耳后肌发育对耳后肌源性反应（PAR）的影响。正常儿童的PAR与小耳畸形儿童健侧耳的PAR之间没有差异。单侧小耳畸形儿童正常侧和小耳畸形侧获得的PAR在波形、潜伏期、阈值或幅度方面均无显著差异。我们的研究结果表明，耳后肌的发育不影响PAR，而且似乎难以用肌肉发育的个体间差异来解释PAR中存在的较大个体差异。
