Sinus The sinuses are small air pockets. The sinuses produce mucus, which is a thin and flowing liquid that protects the body by trapping and moving germs away. Sinuses becomes filled with fluid due to pathologies like blood in case of trauma or chronic infection , resulting in increased radio-opacity and decrease in radiography. 4 sinuses in skull
PARA NASAL SINUS 1. Maxillary (2) 2. Frontal (2) 3. Ethmoid 4. Sphenoid (1 or 2)

Radiography Anatomy
Patient Preparation Inform the patient about the examination and ask the patient to restrict all the movements. Remove all the metallic objects from the skull region . Ask female patients to remove hair clips , bands and other stuff from skull before examination. Take details of dental filling so that it is not misunderstood as artifact or any pathology. Use foam pads in case of children or trauma cases.
The zygomatic arch fracture is easily seen on the OM30 ( Occipito -Mental 30°) image
1 - Orbital floor fracture 2 - Fracture of the lateral wall of the maxillary antrum 3 - Zygomatic arch fracture 4 - Widening of the zygomatico -frontal suture Tripod Facture
Blowout Facture Blowout fractures are caused by increased pressure in the orbit - the orbit gives way at its weakest point, which is the orbital floor The air/fluid level in the maxillary antrum is due to the presence of blood
Mandible Facture
Skull Radiography Parameters Position :- Erect , Supine , Lateral . Factors:- Kvp – 70-80 , mAs - 20-30. Use of Grids , to enhance the images quality. Use of foam pads to support the patient. Collimation as per the requirement . SID = 40inch
