Bilateral maxillary silent sinus syndrome: A case report and literature review

Abstract

Silent sinus syndrome refers to a spontaneous enophthalmos caused by maxillary sinus collapse without any symptomatic sinonasal illnesses. Its prevalence is almost entirely unilateral. The authors report a patient with a bilateral silent sinus syndrome managed successfully by middle meatal antrostomies. This case brings attention to recognizing bilateral silent sinus syndrome. Because of its bilateral involvement, the facial disfigurement might be recognized late due to the symmetrical presentation. This article highlights the pathophysiology and reports the detailed course of such a rare disease. The balloon dilatation is promising as a newly described treatment modality in a patient with silent sinus syndrome, although more long-term data on its outcome is needed.
