  In this paper we consider the growth rates of 3-dimensional hyperbolic
Coxeter polyhedra some of its dihedral angles are $\frac{\pi}{m}$ for
$m\geq{7}$. By combining with the classical result by Parry \cite{Pa} and the
main result of \cite{Y}, we prove that the growth rates of 3-dimensional
hyperbolic Coxeter groups are Perron numbers.
