Editor,—Chronic maxillary atelectasis (CMA),1 also known as silent sinus syndrome (SSS)2 describes the same condition. Typically, the patient presents with acute enophthalmos and hypoglobus in the absence of previous trauma or surgery. Past sinus disease may be present and computed tomograph (CT) scans demonstrate ipsilateral sinus contraction, orbital floor resorption, and thinning with inferior prolapse into the maxillary sinus. We present a patient who noted oscillopsia while jogging 1 year after being diagnosed with SSS.
