I have seen the generalization of octrees being called KD-tree-pyramids. A K-dimensional tree-pyramid (KD-TP) is a full tree where each node represents a K-dimensional subspace.
The most common instances of KD-TP are Full Binary Trees($K=1$), Quadtrees($K=2$), Octrees ($K=3$) and Hexadecatrees ($K=4$).
As Steven mentioned beyond 4D they don´t scale well and kd-trees are used the most.
