X-ray PNS showed opacification of left ethmoidal air cells. The culture of the eye discharge was negative. Which of the following woul'd be most useful further step in evaluation of this patient? [AIIMS Nov 2012]



A CTscan

B Urine culture

C Blood culture

D Repeat culture of the eye discharge

Ans. A CT scan Ref. PL Dhingra 5th/ed pp 213-208.

The child is presenting with fever and purulent nasal discharge with X-ray PNS showing opacification of ethmoidal sinus, . probably the child is having chronic sinusitis (as it is present for the past 2 months) with an acute exacerbation. Now the most dreaded complication of ethmoidal sinusitis is orbital complication.

"Orbital complication - most of the complications, follow infection of ethmoids as they are separated from the orbit only by a thin lamina of bone -lamina papyracea. Infection travels from these sinuses either by ostitis or a thrombophlebitic process of ethmoidal veins."

- Dhingra 5th/ed p 213

The best method to assess the status of ethmoidal air cells and its complications is CT scan.

"Cl' is particularly useful in ethmoid and sphenoid sinus infections and has replaced studies with contrast material."
