Collapsed left maxillary sinus, with depression of the left orbit, in keeping with silent sinus syndrome.

Case Discussion

The silent sinus syndrome represents maxillary sinus atelectasis that results in painless enophthalmos, hypoglobus and facial asymmetry. In general, the condition is idiopathic.

Chronic occlusion of the maxillary sinus ostium / ostia results in gradual resorption of the air. Subsequently, negative pressure is generated within the sinus. This in turn results in gradual inward bowing of all four of the maxillary walls
