Management of enophthalmos and superior sulcus deformity induced by the silent sinus syndrome.
BACKGROUND
Silent sinus syndrome is a dysfunction of the maxillary sinus that induces a progressive and asymptomatic enophthalmos with prominent deep superior sulcus deformity.


METHODS
Two cases of silent sinus syndrome are reported, and the simultaneous management of both enophthalmos and superior sulcus deformity caused by this syndrome is discussed.


RESULTS
The patients underwent surgical endoscopic maxillary meatotomy and transconjunctival subperiosteal implantation of porous polyethylene sheets. The treatment successfully corrected both the enophthalmos and the upper eyelid sulcus deformity. However, small degrees of vertical eye dystopia were observed.


CONCLUSIONS
Silent sinus syndrome is a rare cause of enophthalmos and superior sulcus deformity. Orbital floor implants can be used to increase the volume of the orbital contents, but vertical eye dystopia is likely to be induced if this method of treatment is the only option chosen.
