Let $T$ be a Hochschild extension algebra of a finite dimensional algebra $A$over a field $K$ by the standard duality $A$-bimodule ${\rm Hom}_K(A,\,K)$. Inthis paper, we determine the ordinary quiver of $T$ if $A$ is a self-injectiveNakayama algebra by means of the $\mathbb{N}$-graded second Hochschild homologygroup $HH_2(A)$ in the sense of Sk\"oldberg.
