Facial X-rays (Views)

A number of recent studies have looked at whether a single view (either OM15 or OM30) is sufficient to identify a midfacial fracture.

A review found that although a single view will save time, cost and radiation, a low sensitivity meant that occasionally fractures would be missed [8]. The review suggested that two views should be taken.

In a separate study, analysing midfacial fractures in 104 patients, the lateral facial view failed to identify a single midface fracture seen in either the OM15 or OM30 view [9].

Therefore, the recommended optimum combination of facial views to maximise pick-up rate and minimise radiation exposure is the OM15 and OM30.

In patients where clinical findings suggest a zygomatic arch fracture, a specific arch view such as the submentovertical, will facilitate identification of the fracture.

Two facial views – the OM15 and OM30 – provide the best combination of accuracy in identifying midfacial fractures whilst minimising radiation exposure.
