What is X-RAY PNS?

X-ray of the sinuses or paranasal sinus radiography is an X-ray examination that can be performed with minimal discomfort.

What Are Sinuses?

Sinuses are air-filled spaces (cavities) that are lined with mucous membranes within the skull bones

Who Performs The PNS X-ray?

The PNS X-ray is performed by a radiographer and the image is interpreted by a radiologist.

When The PNS X-ray Is Requested?

• The PNS X-ray is requested when the patient experiences blocked sinuses due to too much mucous build-up, bacteria, and germ which leads to infection and inflammation of the sinuses and is referred to as sinusitis (infection of the sinuses).
• Other sinus-related problems such as deviated septum.
• Symptoms of other infections in the head area.
• To detect injury/ other problems within the sinus.
• To determine the size and location of the tumor or mass.
• To evaluate the patient after sinus surgery.

What Projections/ Views Are Performed?

Routinely three projections/ views are performed which are namely the lateral view, occipital frontal (OF) view, and finally the occipital mental (OM) view.

What Are The Patient Preparation For The PNS X-ray?

Typically there is no special preparation required:

• For female patients who are in the childbearing age capacity, the LMP is asked to ensure the woman is not pregnant.
• The radiographer should be notified if the patient has a prosthetic (artificial) eye as it can cast a shadow causing confusion to the sinus area.
• Patients need to remove objects within the skull/ head e.g. hair clips, earrings.

What Takes Place During The Examination?

• Following this, the patient is advised to remove jewelry or any metal objects from the area of the head.
• A lead apron may be provided for radiation protection.
• Often the patient is positioned in the sitting (upright) position facing the detector. The radiographer positions the patient’s head in three-position whereby either head extended for the OM view; chin tucked for the OF view and the lateral view with the head turned to the side. For all views, it is necessary for the patient to hold still as it will cause blurring of the image and require a repeat examination.

What Happens After The PNS X-ray Procedure?

• There is no special instruction or preparation required.
• The patient is allowed to leave the department once the examination is over.
• The result of the examination will be sent to the requesting doctor.
