  • Title: [Acoustic characteristics of external auditory meatus after tympanoplasty with open mastoid reconstruction].
    Author: Pan S, Wang Z, Jiang Y.
    Journal: Zhonghua Er Bi Yan Hou Ke Za Zhi; 1995; 30(4):239-42. PubMed ID: 8745467.
    Abstract:
    This study investigated the effects of down-wall tympanoplasty (open technique included skeletonizing of mastoid) upon external auditory meatus resonance characteristics. The probe tube microphone measurement was performed twice pre and post operatively. The resonance frequency of external auditory meatus remained constant, but the peak amplitude was increased by 0.83dB SPL (P < 0.05). The results indicated that a tympanoplasty with standard open techniques did not affect the normal external auditory meatus resonance characteristics.
