title: [Acoustic characteristics of resonance after cavity surgery on the ear and their usage in variants of reconstructive operations].
abstract: Acoustic measurements were made of the external and middle ear resonance in health and disease in patients after radical surgery on the ear and in chronic perforative otitis media. It is shown that the absence of the posterior wall of the acoustic meatus deteriorates hearing acuity in the frequency 4000 Hz. Reconstructive surgery of this wall normalizes acoustic resonance of the ear. The value of bone-air interval on pure tone audiogram is different after cavity operation and perforation of the tympanic membrane. Characteristics of acoustic resonance of the ear are decisive for choice of reconstructive surgery.
