Change: The significance of the C1/C2 asymmetry is unknown This is a slit basal view of the zygomatic arches. The patient's head has been "tipped"tilted (laterally flexed) from a true slit basal position to favour demonstration of the affected side (a "teacup view" would arguably have been a better view). View changes from previous version. (Word count: 969)

Change: (the default algorithm/windowing needs some attention perhaps). The algorithm/windowing does not take advantage of the dynamic range of DR imaging.There is limited soft tissue information and the nasal bones are difficult to see. This image was taken on the same DR View changes from previous version. (Word count: 955)

Change: (slight exaggeration) despite that fact that it was taken using a DR machine. This is the default algorithm algorithm/windowing for lateral facial bones for a particular DR machine. (the default algorithmalgorithm/windowing needs some attention attention perhaps). The algorithmalgorithm/windowing does not take advantage of View changes from previous version. (Word count: 965)

Change: This is a PA 20/25 projection of the facial bones. There appears to be evidence of orbital emphysema (black arrow). This is not however orbital View changes from previous version. (Word count: 956)

Change: This is the default algorithm for lateral facial bones for a particular DR machine. (the default algorithm needs some attention perhaps). The image appears much like a radiograph. The algorithm does not take advantage of the dynamic range of DR imaging. This is the same image View changes from previous version. (Word count: 900)

Change: visualixsation visualisation of the bony and sot tissue anatomy. The soft tissues anterior to the anterior nasal spine can give an indication of underling fracture of the anterior nasal spine. These soft tissues appear normal (arrowed). The radiographer has post-processed the DR image View changes from previous version. (Word count: 824)

Change: The radiographer has post-processed the DR image to demonstrate the soft tissues of the face. There is evidence of soft tissue swelling overlying the anterior nasal spine. The anterior nasal spine appears to be fractured. This was confirmed on CT scanning of the skull and face Case 1 This View changes from previous version. (Word count: 762)

Change: arrow at bottom of image).There is no justification for creating an image that is contrasty (pretty) at the expense of it's diagnostic value. This may appear self-evident, but I suspect that this "goal-displacement" is more common than we might be prepared to admit. The OM view tends View changes from previous version. (Word count: 667)

Change: Facial bone soft tissue signs can indicate underlyingbony injury. Good radiographic technique will aid in the visualisation of skull and facial bone soft tissues. The radiographer's goal should be to create an image that displays as much information as possible rather than creating an image that is visually appealing. View changes from previous version.

Compare this soft tissue line with that on the left (blackarrow)(black arrow) ... back to the Applied Radiography home page View changes from previous version. (Word count: 602)

Change: If you are using a digital imaging system (DR or CR) good algorithms and appropriate post-processing are your best friends. Soft tissue signs are of no utility if you cant see them. Consider the two lateral facial bones images shown below. Both images are taken using the same DR machine. View changes from previous version. (Word count: 600)

Change: It is not uncommon for patients to be unaware of facial bone fractures until they develop orbital emphysema. This can be revealed when patients sneeze or strain on the toilet. This is the same image which has been post-processed in View changes from previous version. (Word count: 476)
