Silent Sinus Syndrome

Silent Sinus Syndrome
Silent sinus syndrome is a spontaneous, asymptomatic collapse of the maxillary sinus and orbital
floor associated with negative sinus pressures. It can cause painless facial asymmetry, diplopia
(double vision) and enophthalmos (sunken in appearance of eye). Usually the diagnosis is
suspected clinically, and it can be confirmed radiologically by characteristic imaging features
that include maxillary sinus outlet obstruction, sinus opacification, and sinus volume loss caused
by inward retraction of the sinus walls. Treatment is surgical involving making an outlet for
mucous drainage from the obstructed sinus.
