  In this paper, we deal with the growth and oscillation of solutions of higher
order linear differential equations. Under the conditions that there exists a
coefficient which dominates the other coefficients by its lower $% (\alpha
,\beta ,\gamma )$-order and lower $(\alpha ,\beta ,\gamma )$-type, we obtain
some growth and oscillation properties of solutions of such equations which
improve and extend some recently results of the author and Biswas \cite{b8}.
