The thermal and quark/baryon chemical potential dependences of quark
condensate and masses of $\pi$- and $\sigma$-mesons are studied in the
instanton model of the QCD vacuum in precritical region. The impact of
phonon-like excitations of instanton liquid on the characteristics of
$\sigma$-meson in such an environment is also examined.
