ENT's seem to prefer direct coronal sinus imaging, why ? Do you find this valuable?

I think you mean scanning with the patient in a prone position with the neck extended so the orbito-meatal line is nearly parallel to the table/couch.

Although coronal images can be reformatted from axial images, the direct coronal sinus images provide better visualization of the maxillary sinus ostia (opening that connects the sinus to the nasal cavity). If the supine or head-hanging positions are used, and there is fluid in the sinus, then the ostia can be filled with the fluid and hidden or could imitate pathology.
