title: Acoustic characteristics of reconstructed ear canal after atresia surgery.
abstract: The acoustic properties of the reconstructed ear canals of 13 patients after atresia surgery were investigated by comparing them with those of contralateral healthy ear canals. In the third post-operative month, resonant frequency, amplitude and bandwith of the ear canals with Q-factor were measured. Probe microphone measurements showed a significant shift in resonant frequency in the direction of the higher frequencies, and a non-significant change in bandwith in the atresia surgery group. The suggested reason may be a change in ear canal curvature, altered vibration pattern and sound-absorption characteristics of the skin graft lining the reconstructed ear canal.
