Case Discussion
The Towne view allows better frontal evaluation of the posterior fossa region than a standard nonangled frontal skull view. The lambdoid suture is better evaluated than on nonangled views.
The addition of a Towne view to skull AP and lateral views has been thought to result in better sensitivity for detecting skull fractures than an AP and lateral view alone.
