CT and MRI of masses of the deep face.
By applying these simple concepts of epicenter, vector of spread, and displacement pattern, it is possible in most cases to assign a space of origin to the mass lesions of the more cephalad aerodigestive tract. Once assigned, judicious application of the limited differential diagnostic considerations of the space can often lead to a correct preoperative diagnosis. At the very least, such an approach yields a short differential diagnosis and an accurate presurgical picture for the attending clinician.
