Towne view is used to better visualize the human skull from an angle. It has better sensitivity to detect skull fractures.
What Is Towne View X-Ray?
Towne View X-Ray is an angled Anteroposterior radiograph of the skull, used to evaluate fractures of the skull and abnormal tissue changes like tumors. Towne’s View is also known as Anteroposterior(AP) Axial projection of the skull. This projection is used to visualize the hard petrous part of the pyramids, the dorsum sellae and posterior clinoid processes, which are visible in the shadow of the foramen magnum connecting the base of the skull(cranium) to the spinal canal. The Towne view allows better frontal evaluation of the posterior fossa region than standard non-angled frontal skull X-Rays.
How Is Towne View X-Ray Performed?
Towne View Skull X-Ray is usually performed in a supine position as follows:
- All metal or plastic removable objects from the patient’s head are removed.
- The patient is made to lie down on an examination table below the X-Ray projector.
- Patient’s head is placed above the image receptor perpendicular to the infraorbitomeatal line.
- Radiolucent support like a black sponge can be used to keep the patient’s head in position.
- Both shoulders of the patient should lie in the same horizontal plane, arms comfortably placed.
- Chin is depressed and held still by momentarily suspending respiration for better image quality.
This X-Ray can be performed in an erect seated position if the patient is unable to lie down.
