Abstract: Suppose a $ 2$-handle is attached to a compact orientable $ 3$-manifold $ M$ along an annulus $ A$ contained in a subsurface $ N$ of $ \partial M$. If $ N$ is compressible in $ M$, but $ N - A$ is not, then the Thurston norm is unaffected. This generalizes a series of results due to Przytycki, Jaco, and Johannson.
