Frontal Sinus: X-ray

X-ray of normal frontal sinus. Note the lucency and scallope edges.

Mucosal thickening of left frontal sinus with air-fluid level in a patient with sinusitis.

Paranasal Sinus X-ray: Developmental Variation & Anomalies

 

Note: 5 year old child- frontal sinus not developed yet!

Incidental finding of hypoplastic frontal sinus in an adult.

Asymmetric and under-pneumatized frontal sinus.

 Absent right frontal sinus (occipitomental view).

Paranasal Sinus X-ray: Meniscus Sign

his occipitomental view of paranasal sinus X-ray shows an opacity with a meniscus sign involving the right maxillary sinus indicating presence of fluid usually mucopus in acute rhinosinusitis.  Odontogenic sinusitis has to be ruled out in recurrent unilateral cases.

 Bilateral maxillary sinus opacities with meniscus sign.

 Significant bilateral air-fluid level of maxillary antrum.  Copious mucopus drained during antral washout.

Paranasal Sinus X-ray: Maxillary Fractures with Haemosinus

Traumatic fractures of left maxillary sinus with haemosinus air-fluid level (arrow) in OM view (above) and lateral view (below). 

 

Paranasal Sinus X-ray: Complete Opacity of Maxillary Sinus

Complete opacity of left maxillary sinus.

 Complete opacity of right maxillary sinus.

 

Opaque or hazy sinus may imply presence of fluid, diffuse mucosal thickening, polyposis, or maxillary malignancy.  Bony erosion or sclerosis give clues to more serious aetiology.
