Normal appearances of occipitomental (OM) 30° view of the skull.

Both the OM and OM 30 views will identify these fractures, along with the associated soft tissue swelling over the zygomatic eminence and opacification or an air-fluid level in the maxillary sinus. Often only a straight PA would identify the diastasis at the zygomatico-frontal suture.

2022年1月30日 · 30° occipitomental (30° OM) This projection also shows the facial skeleton, but from a different angle from the 0° OM, enabling certain bony displacements to be detected. OM and 30° OM provide two views of the facial bones at two different angles — therefore in cases of suspected facial fracture both views are needed. Main indications

2024年7月30日 · The occipitomental (OM) 4 or Waters view or parietoacanthial projection 2 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.

Occipito-Mental (OM) and Occipito-Mental at 30 degrees angulation (OM30). Facial bone fractures result from direct trauma and usually follow one of only a small number of patterns. 'McGrigor-Campbell' lines can be used as a simple aid to interpretation. The eye follows these lines to check for these common fracture patterns.

2015年1月12日 · 30° occipitomental (30° OM) This projection also shows the facial skeleton, but from a different angle from the 0° OM, enabling certain bony displacements to be detected.
