medical radiographic view of nasal bone The lateral nasal bones view is a nonangled lateral radiograph showcasing two small oblong bones situated side by side, together forming the nasal ridge. Indications This view is often primarily used in assessing various nasal bone fractures in the trauma setting. Depending on the department, this view may be done bilaterally (for comparison of affected versus unaffected side) or unilaterally (only affected side). 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 Technical factors lateral projection centering point 1.25 cm inferior to nasion collimation within 5 cm of the nasal bones on all sides 1 orientation for unilateral side: portrait for bilateral side: landscape detector size 24 cm x 18 cm exposure 60-70 kVp 5-10 mAs SID 100 cm grid no Image technical evaluation nasal bones with soft tissue nasal structure, frontonasal suture (superior) and anterior nasal spine should be demonstrated nasal bones should be seen with no rotation Practical points remove glasses and nose piercings to avoid artefact obscuring important pathology this view should not replace a lateral facial bones x-ray as this projection is often requested together with a facial bones series 3, there may be the temptation to combine the request and only image a lateral facial bones x-ray as per ALARA. However, nasal bones and their soft tissue nasal structures are less dense compared to the denser facial bones and should hence be imaged separately to prevent over exposure of the less dense region
