Silent Sinus Syndrome
Silent Sinus Syndrome Definition
Silent sinus syndrome is a spontaneous, asymptomatic collapse of the largest paranasal sinus (maxillary sinus) and orbital floor linked with negative sinus pressure; which can often result to painless facial irregularity, double vision (diplopia) and recession of the eyeball within the orbit known as enophthalmos. Diagnosis of silent sinus syndrome can be confirmed radiologically through distinctive and characteristic features of images. This would include obstruction or blockage in the maxillary sinus outlet, sinus opacification, and sinus volume loss due to the retraction of the sinus toward the inside. Surgical treatment is an option, which involves creation of mucous drainage outlet from the blockage in the sinus.
