Position: Skull Haas Reverse Towne
The Haas projection is a reverse Towne view used when the patient cannot flex the neck for standard Towne. The beam is angled cephalad through the occiput to project the dorsum sellae into the foramen magnum. It evaluates occipital fractures and cranial base pathology. Proper positioning prevents elongation of the skull. It is a recognized ARRT alternative projection.
