What is Open mouth view?

What is Open mouth view?

An open mouth view x-ray is a special view to visualize upper cervical spine problems especially C1 and C2 vertebrae. Odontoid process is part of the second cervical vertebra that projects upward to articulate with C1 vertebra. The open mouth view x-ray is also called Odontoid view or odontoid peg view.

How do you open mouth view?

C: For the open-mouth view, the patient is positioned in the same manner as for the supine AP projection; the head is straight, in the neutral position. With the patient’s mouth open as wide as possible, the CR is directed perpendicular to the midpoint of the open mouth.

Why do you have to open your mouth for a neck xray?

The open mouth odontoid radiograph (x-ray) is used to assess for the presence of an upper cervical spine injury. Common injuries to the upper cervical spine include: Dens Fracture (i.e., C2 Odontoid Fracture) Jefferson’s Fracture (i.e., C1 Burst Fracture)

How do you do Odontoid view?

Patient position

  1. patient positioned erect in AP position unless trauma the patient will be supine.
  2. patient’s shoulders should be at equal distances from the image receptor to avoid rotation, the head facing straight forward.
  3. at the last instant, the patient is instructed to open their mouth as wide as possible.

What is Occipitomental view?

Waters’ view (also known as the occipitomental view) is a radiographic view, where an X-ray beam is angled at 45° to the orbitomeatal line. The rays pass from behind the head and are perpendicular to the radiographic plate. It is commonly used to get a better view of the maxillary sinuses.

What is the Odontoid view?

Odontoid view shows displacement of the lateral masses of C1, allowing distinction of this fracture from a simple fracture of the posterior neural arch of C1.

Can neck Xrays show tumors?

X-rays of the spine, neck, or back may be performed to diagnose the cause of back or neck pain, fractures or broken bones, arthritis, spondylolisthesis (the dislocation or slipping of 1 vertebrae over the 1 below it), degeneration of the disks, tumors, abnormalities in the curvature of the spine like kyphosis or …

Why is it called Water’s view?

It is commonly used to get a better view of the maxillary sinuses. Another variation of the waters according to Merrill’s Atlas of Radiographic Positioning and Procedures places the orbitomeatal line at a 37° angle to the image receptor. It is named after the American radiologist Charles Alexander Waters .

What is the open mouth projection in radiology?

The odontoid or ‘peg’ projection, also known as the open mouth AP projection (or radiograph ), is an AP projection of C1 (atlas) and C2 (axis) with the patient’s mouth open. This view focuses primarily on the odontoid process of C2, and is useful in visualizing odontoid and Jefferson fractures.

When to use an open mouth odontoid Xray?

The open mouth odontoid radiograph (x-ray) is used to assess for the presence of an upper cervical spine injury. Common injuries to the upper cervical spine include: Dens Fracture (i.e., C2 Odontoid Fracture) Jefferson’s Fracture (i.e., C1 Burst Fracture) Transverse Ligament Injury Basilar Invagination

Which is the open mouth projection of cervical spine?

Cervical spine (odontoid view) Dr Daniel J Bell ◉ and Andrew Murphy ◉ et al. The odontoid or ‘peg’ projection, also known as the open mouth AP projection (or radiograph), is an AP projection of C1 (atlas) and C2 (axis) with the patient’s mouth open.

What are the masses of the open mouth impact?

The open mouth impact allows the study of the atlas (C1) and axis (C2), with the lateral masses of the atlas, the dens of the axis and atlanto-occipital and atlanto-axial joints.
