Structure of the torus of the Active Galactic Nucleus
This question was asked more roughly 8 years ago, and for 2 years there is a review article around which I found worth mentioning and summarizing. The manuscript is called Redefining the torus:  A unifying view of AGN in the infrared and sub mm and work of Sebastian Florian Hönig. Here an excerpt of the abstract:

The advent of high-angular resolution IR and sub-mm interferometry allows for spatially-resolvedobservations  of  the  parsec-scale  environment  of  active  galactic  nuclei  (AGN),  commonly  referred  toas the “torus.”  While molecular lines show the presence of large, massive disks, the IR observationsappear to be dominated by a strong polar component that has been interpreted.

The main result seems to be the following schematic picture (Fig. 4 of the manuscript) of the AGN which is an overlay of various observations:


The purple ring are observations in the near-IR.
The yellow torus and the gray dashed lines are from ${\rm H}_2$ emission.
The main brownish cone is from mid-IR.
The redish wobbly plane with the red (solid) arrows and the purple (dashed) arrows are sub-mm obseravtions (${\rm CO/HCN/HCO^+}$)
Bright green dots on the $x$-axis are ${\rm H_2 O}$ maser emissions.
