33. 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

34. PARA NASAL SINUS
 1. Maxillary (2)
 2. Frontal (2)

 4. Sphenoid (1 or 2)

40. 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.

41. Clinical Indication of Cranium
 Factures
 Neoplasm
 Paget’s Disease
 Pituitary Adenomas
 Mastoidits
 Sinusitis
 Multiple Myeloma
 Sclerosis
 Acoustic neuroma
 polyps

46. The zygomatic arch fracture is easily
seen on the OM30 (Occipito-Mental
30°) image

47. •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

48. 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

49. Mandible Facture

50. 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
