What view nasal bones?
The fetal nasal bone at 11–13 weeks’ gestation is classified as present or absent. For examination of the nasal bone, the image should be magnified so that the head and the upper thorax only are included on the screen and a mid-sagittal view of the fetal profile should be obtained.
How do you X-ray water view?
Patient position
- the patient is erect facing the upright detector.
- the chin is raised until the mento-mandibular line (MML) is perpendicular to the receptor (OML will be 37° from receptor)
- ensure patient’s head is straight.
What is Waters view used for?
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.
How do you X-ray a nasal bone?
Patient position
- rest the lateral aspect of the patient’s head (with the side of interest) against the image detector.
- adjust the head into a true lateral position, with the midsagittal plane (Figure 1) parallel to the image detector.
- for patient’s comfort, adjust the patient’s body into an oblique position.

How do you check for a broken nasal bone?
A good physical examination of the internal and external nose is still the method of choice for detecting and assessing nasal fractures. For questionable fractures and fractures that may be associated with other facial trauma, a CT scan of the facial bones without contrast is an excellent choice.
What is the reason an open mouth waters method is done?
Indications. It can be used to assess for facial fractures, as well as for acute sinusitis. In general, radiographs of the skull and facial bones are rapidly becoming obsolete, being replaced by much more sensitive CT scans.
What is Reverse Towne projection?
REVERSE-TOWNE PROJECTION. (OPEN-MOUTH) Image Receptor and Patient Placement The image receptor is placed in front of the patient, perpendicular to the midsagittal and parallel to the coronal plane. The patient’s head is tilted downward so that the canthomeatalline forms a 25- to 30-degree angle with the image receptor.
What is a Waters view xray?
: a radiographic image obtained by passing a beam of X-rays through the chin at an angle and used especially to obtain diagnostic information in a single X-ray image about the bony structures of the front of the head and especially the maxillary sinuses and frontal sinuses.
When should you suspect a broken nose?
Bruises around the eyes — a look of “black eyes” A crooked nose. Tenderness when touching the nose. A grating or crunching sound when touching the nose.
What is a nasal bridge?
Your nasal bridge is the bony area at the top of your nose. If you have a low nasal bridge, that area is flat and doesn’t protrude. The degree of flatness can vary depending on the person. A low nasal bridge is completely normal for many people of Asian and African descent.

The occipitomental (OM) or Waters view is an angled PA radiograph of the skull , with the patient gazing slightly upwards. It can be used to assess for facial fractures, as well as for acute sinusitis. In general, radiographs of the skull and facial bones are rapidly becoming obsolete, being replaced by much more sensitive CT scans.
What should I know about nasal fracture imaging?
Nasal Fracture Imaging 1 Practice Essentials. Although nasal fractures are the most common facial fracture in both adults and children, [1] they often go unnoticed by physicians and patients. 2 Radiography. Features of the Waters and lateral radiographic views of nasal fractures are discussed in this section. 3 Computed Tomography.
What are the radiographic positions of the nasal bones?
Patient prone or upright 3. Patient positioned with chin on table, O.M.L. forms 37o angle with plane of film 4. Bucky 6. Central Ray: passes through acanthion 7. This view can demonstrate a deviated nasal septum 2. Patient prone 3.
How is the waters view of sinus computed tomography obtained?
The Waters view is obtained with the chin raised and placed on the x-ray cassette and with the nose 1-1.5 cm off the plate while the x-ray beam stands perpendicular to the cassette. In this projection the frontal and maxillary sinuses as well as the nasal cavity are well appreciated.
