[The dynamics of two-layer graft acoustic properties at different times after myringoplasty]. / Dinamika akusticheskikh svoistv dvukhsloinogo transplantata v razlichnye sroki posle miringoplastiki.

A two-year follow-up tympanometric results have been analysed for 40 patients subjected to myringoplasty. Ultrathin allocartilage was used as one of the transplant components. The static compliance of the neotympanic membrane seemed to change in a wide range, but the changes did not affect hearing. The formation of an adequate neotympanic membrane takes place by the end of the second year after the operation.
