Silent Sinus Syndrome: A Case Report and Review of Literature

Silent sinus syndrome is a rare condition affecting the maxillary sinus, resulting in spontaneous collapse of the sinus walls causing facial asymmetry and unilateral enophthalmos. The exact etiology of this condition is unknown. We report a case of a 20-year-old male presented with facial asymmetry with depression of right cheek associated with heaviness over right cheek, without any disturbance of vision or eye movement. Computed tomography (CT) scan of the paranasal sinus showed a relatively smaller and opacified right maxillary sinus with inward retraction of the roof, medial and posterolateral walls. He underwent endoscopic middle meatal antrostomy. On follow-up, patient is free of symptoms and the CT scan showed well-ventilated sinuses with arrest of the disease progression.
