Silent sinus syndrome

In Silent sinus syndrome the sinus is usually fully opacified , not in our case, and reduced in volume with inward bowing of all four walls.
We see inferior bowing of the orbital floor and lateral bowing of the medial wall , lateral displacement of the middle and inferior turbinate
posterior bowing of the anterior wall : flattening of the malar eminence
