Topoloical index is a numerical quantity which is correlates to properties of chemical compound . In this paper, we define operator graph namely, Edge $ss-$corona graph and we study structured properties of that graph. Also, establish the upper and lower bounds for First Zagreb index, Second Zagreb index, First Gourava index, $SK_{1}$ index, Forgotten topological index and $EM_{1}$ index of edge $SS$-corona graph.
