Ethmoid Silent Sinus Syndrome Following Orbital Trauma

A 55-year-old man presented with progressive "enophthalmos" of his ocular prosthesis, 12 years after secondary orbital implant placement following evisceration of a severe traumatic globe rupture. The medial orbital wall was found to be displaced inwards, associated with ethmoid sinus opacification, and consistent with post traumatic silent sinus syndrome affecting the ethmoid paranasal sinuses. The authors present the clinical and radiological findings, review the literature on silent sinus syndrome of nonmaxillary sinuses, and discuss the possible mechanisms for his presentation.
