Exophthalmos and orbital floor thickening related to maxillary sinusitis.
A 59-year-old woman presented with periocular pain and 1.5 mm of relative proptosis. A computed tomography scan demonstrated thickening of the orbital floor, and an endoscopic sinusectomy revealed chronic sinusitis. Although cases of maxillary sinus disease with orbital floor thickening have been reported, these findings are in contrast to cases of silent sinus syndrome, in which maxillary sinus disease induces thinning and inferior displacement of the orbital floor with secondary enophthalmos and hypoglobus. Thus, while chronic maxillary sinus disease may create negative antral pressure and inferior displacement of the orbital floor, whether orbital floor thinning or thickening occurs varies with each case. The present case represents a combination of maxillary sinusitis with orbital floor thickening and exophthalmos, a less common manifestation of maxillary sinus-related orbitopathy.
