A frontal sinus mucocele presents with proptosis and inferior displacement of the globe. In which direction does the eye typically get displaced by an expanding frontal sinus mucocele?

• A Upwards and inwards
• B Upwards and outwards
• C Downwards and inwards
• D Downwards and outwards ✓

Explanation

D frontal sinus mucocele expands into the orbit, displacing the globe downwards and outwards (inferolaterally). An ethmoid mucocele displaces the eye laterally, and an maxillary mucocele displaces it upwards. Recognition of the pattern of globe displacement on examination helps localize the sinus of origin before imaging confirmation.
